Zeiss 35 Biogon Review

Zeiss Zm 35 C-Biogon 2.8 Lens Review – Wow, it seems like it was just a couple of days ago that I posted my Zeiss ZM 50 Planar review (see it here). Wait, that WAS a couple of days ago! Ha ha. Well, it’s that time again and today I am writing about and testing the Zeiss ZM 35 2.8 C-Biogon. This is slower and smaller than the well reviewed and loved Zeiss ZM 35 F2 Biogon. I wanted to test out the F2 but Zeiss sent me the 2.8 instead. That is why I am wearing a T-Shirt today that says “I asked Zeiss for a 35F2 but all they sent me was this crummy 35 F2.8″. All joking aside, I am happy they sent me this lens as I have been hearing some good buzz about it lately. Plus, the fact is that the C-Biogon 2.8 is only $50 less expensive than the F2 version! Hmm. I wanted to know why. Finally, as hard as I looked I could not find any real reviews of this lens anywhere!

Here is the press release hoopla from Zeiss on this lens:

OBERKOCHEN/Germany, 19.03.2008.

As the latest member of the ZM lens family, the C Biogon T* 2,8/35 ZM lens is the perfect addition to your light, mobile photo equipment. The C Biogon T* 2,8/35 ZM will inspire you with perfect images, even at full aperture. Together with the compact C Biogon T* 4,5/21 ZM, it creates the ideal equipment for a wide range of applications such as documentation and architecture photography.

The “C” in the title indicates another outstanding feature: rather unusual for a lens of this performance class, its moderate speed of 1:2.8 permits an exceptionally compact construction. The symmetrical Biogon construction with 7 lens elements in 5 groups allows for practically distortion-free images.

The ZM lens series from Carl Zeiss is suitable for cameras with M-bayonet. As with the other lenses in this line, the C Biogon T* 2,8/35 ZM features an intuitive operating concept, a robust all-metal frame and a precise, noticeable click in 1/3 aperture stops.

Looks pretty sweet in Silver on the black M9

So it seems you are paying for the reduction in size as well as the supposed stellar wide open quality of the lens. For me, it passed the first test which is build and feel. I was going to do a youtube on this one but realized there was nothing to really show that you can not see in the picture above. So, for this one, no video :( But, you do get to see the weight on the Huff-O-Matic scale and the lens comes in at a light 6.3 oz.

scale

As you can see in the shot above the scale, the lens looks great on the camera. Its small, light, and the build is nice. When I took it out of the box the focus ring felt very silky smooth and the aperture ring was smooth but solid. It seemed better made than the Zeiss 50 Planar but as I said in that review, the Planar that was sent to me was a bit worn out as it looked like it has been used quite a bit.

The 35 C-Biogon build and feel is nice and up there with a Leica 28 Elmarit but with an even smoother aperture ring. Yes, this lens is made well. In case you did not know, nearly the entire ZM line is made in Japan even though two Zeiss ZM lenses are manufactured in their German factory. The $4000 15 ZM and the beautiful 85 F2. These two lenses come at a price premium but I hear they are absolutely wonderful hunks of glass.

I have had four Zeiss ZM lenses in hand for the last month or so but due to all of the other gear flowing to my mailbox, I have not been able to shoot these lenses as much as I hoped. Zeiss was cool and allowed me to keep them longer so I could shoot more. I am glad they did that because the more I shot with this 35 C-Biogon, the more I realized that this was a special lens. Yea sure, I shot with both of the big gun Leicas, the 35 Summicron and 35 Summilux but with those lenses you are paying for speed/rep/build. In regards to image quality, this Zeiss seemed to give me superb results up there with the Summicron.

Not everyone has a few thousand bucks to shell out on a little 9 ounce piece of glass and this Biogon fills a gap in M mount lenses. On one end you have the cheapest of the M mount lenses, the Voigtlanders. Then you have Leica at the top of the cash heap. Right in the middle you have Zeiss, and truth be told here…just keeping it real, the Zeiss ZM line comes damn close to Leica. For example, the closest competitor in Leica land to this Zeiss 35 2.8 is the Leica 35 Summarit 2.5. It comes in at $1595 (going up in Jan 2010) compared to the $850 of this Zeiss.

That is ALMOST double the cost for the Leica, but you do get a well engineered German made lens and a pouch. While I have yet to review the 35 Summarit I have seen results from it and it looks AMAZING and you get a little bit of a faster lens with 2.5 vs 2.8. What I am trying to say here is that the Zeiss would probably stand toe to toe with the Leica Summarit at almost half the cost. I hope to test the Summarit soon.

SO HOW SHARP IS THIS LENS?

As I do with all lenses, I attached this lens to my camera and shot with it as much as I could over a 4 week period. I also took some test shots of a Christmas scene in my house but what it told me was that this lens is sharp from 2.8 all the way through its aperture range. Instead of showing you those rather boring tests, how about I put up some FULL SIZE out of camera samples so you can download them and judge the lens quality for yourself.

BTW, the first two are straight from camera and have not been processed! The third of the old house and tree has been converted from RAW using Adobe Camera Raw and then converted to Black and White using Nik Color Efex Pro. Yes, COLOR Efex pro. :) I then used Nik Viveza to add a little fill light to the house. Thats it.

After shooting with this lens and seeing the magical results even I was ready to plunk down my cash! But wait, I was OUT OF CASH! So damn, I couldn’t do it. Honestly, if you do not need a fast lens with a 1.4 or F2 aperture then this Ziess really has the 3D depth and sharpness that the ZM line, and Zeiss are known for. This little 35 gave me great result after great result, and for scenes like the house above it, will destroy the little Voigtlander 35 1.4 (review) I reviewed a couple of weeks back. But that lens is meant for low light shooting, not landscape shots. This Zeiss is sharp enough to get the landscape shots, and it also injects a healthy dose of that “Zeiss Mojo”. But it will not do the special low light dreamy bokeh portrait as its a 2.8 lens.

I am now sitting here wondering if the Zeiss 35 ZM F2 Biogon is as good at F2.8 as this C-Biogon. I hope to review that lens soon along with the Zeiss ZM 50 Sonnar (again). But back to the C-Biogon, the COMPACT Biogon! Here is one more test image with a crop. Its my Banana test shot! Click the image to see the correct size with crop.

bannanatestThis is impressive for a lens shot wide open and with NO sharpening applied at any time. I am also liking the color and contrast here as well. I am now going to have to ask Leica for the 35 Summarit to test as I would love to see the differences in color, contrast and detail and see which one I prefer.

WHAT ABOUT BOKEH?

Ahhh yes! The Bokeh! What would a lens be without beautiful bokeh? It’s true, I have seen may lenses that gave me a nice sharp image but had nasty out of focus background renderings. I think the worst of all time (that I owned) was my old Nikon 50 1.4. I enjoyed that lens on my old Nikon D700 but when I look back I think about how busy that bokeh could get. Here is a one of my old samples that shows some nasty “bokeh” from the Nikon 50 1.4. My processing did not help that shot out one bit :)

The Zeiss 50 Planar had wondeful smooth bokeh and while this 35 2.8 may not be in the same league, it is not bad. What do you think? These are all wide open at 2.8 on the Leica M9. I also noticed  this lens just does not flare, or at least I could not get it to flare.

With the lens being a 35 and a 2.8, you will not get crazy bokeh like a 50 1.4 or a Noctilux, but I was pleasantly surprised. It almost seems like this Zeiss gives you a look almost like an F2 lens. Its not, but you still get some nice background blur if  you want it.

That is about all I can say about this lens. It’s pretty sweet and I cannot imagine anyone being disappointed in in on a Leica M7, M8 or M9.


Here is my pro/con list of the lens..

PROS

  • Its size! Its compact and well made.
  • The price! About $800 for a 35 2.8 prime for Leica M mount that you wont have to mortgage the house for.
  • The color and 3D pop is here, and there is plenty of it.
  • Comes in Black or Silver!
  • It’s sharp as I would ever need. No dull/flat images with this lens.
  • No issues with magenta color casts and I used it without the m9 coding menu. In other words, I did not set it up as a 35 Summarit in camera, and it did great.
  • Pretty much flare resistant!

CONS

  • Its somewhat slow at 2.8.
  • The lens has some slight vignetting at 2.8, but its slight.
  • A few times it seemed the lens caused my M9 to underexpose by a half stop.
  • It’s not 6-Bit coded but does bring up the 35mm frame lines.
  • Does not come with a hood or case/pouch.

MY BOTTOM LINE CONCLUSION FROM MY REAL WOLRD USE

The Zeiss ZM 35 C-Biogon 2.8 lens is a lens I probably would have never thought of buying due to its somewhat slow-ish 2.8 max aperture. But, I am very glad Zeiss sent this to me as I now know what a powerhouse of a lens it really is. Small, light, and with a good build quality,  this lens shines at every aperture. If you want a small 35 that wont break the bank, comes in silver or black, and delivers the warm color along with the Zeiss 3D pop, then this may be the lens you are looking for.

While not a low light or night time lens it does extremely well in bright sun, flare is virtually non existent (and I was NOT using a hood) and the overall balance of image quality leans to the warm side of neutral. In comparison, the Leica 35 Summicron leans on the cool side of neutral. Any way you look at it, this Zeiss 35 C-Biogon lives up to the claims laid out by Zeiss. It is small and compact and can be used even wide open with great results. All at a price that won’t break the bank. In the world of F2.8 35’s, I do not think I have ever enjoyed one more than this.

  1. Zeiss is doing a great job with these lens line up. How do you set up the lens coding on the M9 ?

  2. Good Review…………you keep my possibilities open.I should be ready for M9 in
    March.Sooner if I sell a few pieces…………….Glass has always been my issue.
    But Zeiss seems to be a nice alternative……………Thank You Steve.

  3. Nice Same question f2 or 2.8 =) 50 planar is on the list =)

  4. Steve – I really like the last picture. Very nice review of seems to be a quite capable lens.

    • Hi Steve,
      In France the Leica community people is even ready to exchange the C biogon 35 against the Summarit… to save 600€. Youcan take a look at “photim chasseur d’image web at Leica forum”

  5. I think if you had coded the 2,8/35 ZM as the Summarit 35/2.5 in the M9 lens menu, you wouldn’t get vignetting at F2.8. I think that is an artifact of the sensor, not of the lens. You should try and confirm, though. ;)

  6. I had this lens and stupid as I am sold it. Now I want it back!

  7. Back in the day I had the Zeiss 35/2 on my RD-1. I LOVED that lens. I had no idea that Zeiss made a smaller version of it. If I can ever get my hands on a M9 I’ll be sure to look to Zeiss for my 35mm lens. Thanks for the great review and reminding me what wonderful glass Zeiss offers!

  8. Thank you for posting the only review of this lens I have found! The picture of the flock of birds is really nice, so full of life.

    I was hoping for a comparison shot with the Summicron asph., just to see if they render differently. Did you take any side by side shot with your Summicron asph.?

  9. How does the Biogon-C f2.8 compare with the Biogon f2?

  10. Thanks for testing this perfect lens

    I am Zeiss lens fans, here,, most people use 35/f2 more than any other zeiss lens , of course, every one give top remarks on the new design lens , hope you can test it on your wonderful M9

    For myself and other friends, I prefer 28 as my standard lens, but we are sorry to see the MTF of the ZM 28 is not good as the 28 on the CONTAX G system (and the price of G Lens now is like a vegetable). As we know, we can not trust the MTF only; we are waiting for your series testing of ZM 28

    By the way, I have zm25 before, it is perfect lens I never have, but it too wild and I can not control.

  11. Hi Steve ,

    Would love to see you do a review of the Zeiss 50mm 1.5 ZM Sonnar lens . Just received mine today , to use on a Leica M6 , but as yet have not used it . Like my Leica lenese , but they are on the cool side . As a result I have acquired a lot of Contax cameras and Zeiss lenses for them . Love the 85mm F 1.4 lens . Have never really shot lenses wide open , but am looking forward to trying the 50mm F 1.5 Sonnar ZM at 1.5 for some shots . I love your website . Please keep the Zeiss ZM reviews
    coming . I think that there are a lot of Leica folks out there who love the Zeiss lenses , or would if they tried them .

    Love your reviews . Please keep them coming .

    Regards ,

    Bill Hayden

  12. Hey Bill,

    I did do a review of the Zeiss Sonnar but on the M8. You can access it by using the Nav bar above and click on “Leica Reviews”. Thanks!

    Steve

  13. I am seriously considering between the ZM 35/2.8 and 35/2. I already have a VC 35/1.7 Aspherical and a Summilux Asph. therefore the extra stop for the 35/2 is not a big deal to me and the price difference is too little to be a factor for consideration. However, I visited a local New and Used camera store that specialized in Leica equipment last week, the store owner is a very experienced film shooter but has less experience with digital. He told me that, the ZM 35/2’s overall performance is on par with the 8-elements Summicron. That is a very interesting selling point as the 8-elements Summicron has been highly praised (at least in HK). In addition to 8-elements Summicron, he has also compare the ZM 35/2 against the 7-elements and Summarit and found that the ZM 35/2 has superior performance as compare to these 2 lenses.

    I am sure his judgment from his valuable experience in the photo industry should be credible and reliable. However, through the years that I have known him, he mainly shoot B&W film in which the 8-elements would excel because of its contrast level which was designed for B&W film. And if he says the ZM 35/2 is on par with 8-elements, I think he meant the B&W film performance. I am not sure how well the ZM 35/2 and 35/2.8 would turn out on my M9.

    I do own a ZM 50 Sonnar 1.5, which when I compared to my Summicron and Summilux Asph, it is very vibrant but does not perform as well wide open. I do its moody feel which makes the picture more alive. If the ZM 35/2 or 35/2.8 would have similar color reproduction and good wide open performance, I would get one of them in a heart beat.

  14. Kevin the general rule is that zeiss is warmer in tone and general design is to get reproduction close to medium format imagery as possible.

    Next point is that a lens is like the painters brush so erogonomics play a part. ZM 2.8 or 2 would probably base on your hand size.

    If you prefer the leica look I like 35 f2.5. It is a good middle ground b/w painterly oof and realistic in focus sharpness with smooth transition

    I have the 35f2 pre asph V4 which is not to my taste due to sharpness issue. Another thing is its resolution power may not be up to scratch with the M9 sensor. If you have any intention of printing big 17*22 inch V4 might not be ideal. But mine is a fair condition lens so that might be why….
    I’m am an M9 user.

    I love my VC 35 1.2

  15. I picked up my ZM 35/2.8 last week and took it to Bangkok with me, really love the compactness of the lens and the color reproduction. Will try to post some pictures later.

  16. Doesn’t the C mean CLASSIC and not compact? Like the 50 1.5 Sonnar C?

  17. Would you suggest using this lens or a 2.0 with an adapter on the Sony Nex for travel? I’m pretty new to this.

  18. I’m considering saving for this lens or the Nokton 35mm f1.4 SC. Not sure as to which one to buy just yet.

  19. [...] is this to be very a competent lens. As a further guidance there's a review from Steve Huff too: The Zeiss ZM 35 C-Biogon 2.8 Lens Review | STEVE HUFF PHOTOS Sure, this lens is very a tempting proposition if one can live with the relatively low speed. [...]

  20. How does this lens compare to 35mm f/1.4 Nokton? Which one you pick for optic quality?

  22. Thanks for review Steve!have you ever try the Zeiss T* biogon 28mm 2.8 on OMD EM5,is that good,too?..i want to but that lens for my OMD but i want to ask you before..:)

  23. Hey Steve, I shoot a 35 ‘cron ASPH on an M6 exclusively with slow B&W (usually ISO 100) and have been thinking about another 35 that might give a different look. Any thought about this 35C vs CV 35/2.5? Anything to be gained or discernible in difference compared to my lovely Leica or should I save my €€££¥¥ and stick with the goodness I already own?

  24. Hi Steve
    I have a M6 classic with a 50mm Cron. Considering this lens for landscape images color and B&W, what do you think?

    Thanks,
    Victor

  25. Hello Steve,

    Just waiting for mine to arrive. Have been using a Voigtlander 35mm f2.5 P for years – great lens but expecting big things from the Zeiss. Great review by the way. Thanks

    Phil

  26. Hello Steve,

    Just received the lens. Managed a few shots in between the rain showers and a few indoors. What a lens! Sharper or as sharp as any of my Leica glass. Shot some indoors at f2.8 – fantastic.

    The feel and quality of construction is also a revelation for the price. My first and certainly not my last Zeiss lens.

    Phil

  27. Thanks a lot for your review!
    I ended up buying this lens. I sold my voigtlander 35mm f1.4 and got this one. No looking back! I absolutely love this lens on my M6!
