But often smaller lenses with less elements mean a sacrifice in edge sharpness and overall contrast. But not thews little beauties.
I have always been a fan of Zeiss glass particularly some of the older Zeiss Contax lenses which are small and very compact.
Enter Touit - Now I can't honest tell you I understand what Touit means, Wikipedia say "Touit is a genus of Neotropical parrots in the Psittacidae family.." en.wikipedia.org/wiki/Touit but moving on from the name lets take a look at these lenses.
They are autofocus lenses in two focal lengths. And ether are two lens mount options currently. Sony E Mount and Fuji X mount. 12mm f2.8 Planar 32mm f1.8 Distagon
While not specifically designed for shooting video I was curious to see how they'd perform since you can attach them to any E-Mount camcorder.
I wanted to see how they'd get on fixed to the Sony FS700.
Note: the autofocus did not seem to work on the FS700 - not a big deal because I never use autofocus on that camera anyway, but it did work on the NEX-5n.
I should say at this point I only had a very small window to shoot with these and so the film below is really only a series of shots I filmed after a monumental downpour on Saturday afternoon.
The focus is electronically driven and you can feel the motor working within the lens housing. But they are really responsive and felt just like a manually driven focus barrel. I did number of pull focus tests to test just how responsive it was and I was really pleasantly surprised.
Clarity and contrast
Often with smaller compact lenses , image clarity and contrast are compromised because fewer glass elements are present. Not the case with Touit. Th edge to edge sharpness is incredible even at wider apertures. I purposely shot stiff at f2.8 to test this. The images have great clarity also and the contrast levels are exactly what I've come to expect from Zeiss.
I've done some previous comparisons with canon lenses that began life as part of my BlackMagic European Roadshow last year and the additional warmth and contrast from Zeiss is evident. You can see that comparison video here http://www.fstopacademy.com/blog/what-difference-does-a-lens-make/
