Since getting the Voigtlander Nokton 17.5mm f0.95 for Christmas 2012 it has been almost permanently attached to my OMD. It’s big, heavy and expensive for a Micro Four Thirds lens but boy is it great. Paired with variable ND filter this lens can do anything. During the day the ND filter is invaluable and allows me to shoot great shallow depth of field shots with the lens on f0.95, come night time and the ND is just like a lens cap that I screw on and off between shoots.
There is not a huge amount of vignetting with the Nokton although I like to add some for effect, especially in the Australia beach house shot. I find the best colour setting for this lens on the OMD is Vivid, something I never use on Auto Focus Micro four thirds lenses, but I do tend to use on less contrasty MF lenses. Focusing is a breeze now that we have the Focus Peaking workaround for the OMD.
The really important thing about this lens is the fact is sharp wide open, it really takes my photography to a new level.
Thanks and keep up the great work,
