CZJ PRAKTICAR (Flektogon) 35mm F2.4 Dismantle/Adapt for 5DII
I am amazed by my first test results with this lens, once I got it centred. (I used the usual large brick wall for setting up the centring. The difference of tightening and loosening the 3 set screws is very noticeable, and straightforward to get all the edges equal. Also this lens has very little curvature of field (at my test subject distances of 10' and 250')
At its best, at F8, it is beautifully sharp and fairly contrasty, from corner to corner. I haven't compared it yet with my Canon FD 35mm F3.5 TS, but at sharpest I think it would be a tie, even closely approaching the levels of the Contax Vario-Sonnar 35-70/3.4, which quite frankly amazes me.
Even at F2.4-F4 it is surprisingly sharp in the centre (at least at 250'), but I don't yet know how it performs close at F2.4 -F3.5 where I intend using it most, for close ups. (although at f2.4 the edges are soft and the extreme corners just smears)
These are taken in sunny conditions, and near midday. IMG_5444_Lr5-3 by Timothy Ball, on FlickrTimothy Ball[/url], on Flickr@250' distance, 1:1(100%), F8 centre = edge = corner! Note the power lines JUST visible above the horizon to the right of the tree , they're about 2 miles away, and a real test for all my lenses!
Left edge 100% F8. The power lines are clearer here. IMG_5453_Lr5 by Timothy Ball, on Flickr ..and yes that is a window handle! (I'm shooting through my open study window.)

The closest focus is 0.22 m from sensor register, which works out at 10cm or 4\" from the lens front.
