Review: Canon FDn 50mm f:1.2

Canon New FD 50mm 1:1.2 lens review.

This lens is always stays in the shadow of top rated ‘L’ designed with using of aspherical elements, but it looks unfair – too big difference in prices with much less difference in IQ.

LensWars: Canon FDn 50mm f/1.4 vs. Minolta MD 50mm f/1.4

This comparison is correct only for conditions and equipment used for tests. Test results can be differ if any element is changed.

I consider this article to be the my most serious attempt to answer the question – which 50mm F1.4 lens is better – Canon New FD or Minolta MD.
There are many such comparisons on the Internet. But not one of the known for me does not satisfy me. The reasons are different: some has been made on a crop camera, some compares 58mm lens with a 50mm lens from the same distance, some compares Canon New FD with Minolta Old MC. Someone simply makes mistakes in focusing, or does not remember about the field curvature. Or performs the tests at a distance of 50 cm and in the center only.

But this is a very important comparison. The fact is that such lenses, 50/1.4 – are the main point of the product lines for all serious companies. Having of the best fast fifty in production line can be named as ‘companies honor’. Even for today. As you can see, I understand the responsibility.

Regarding to Canon FDn 50/1.4 and Minolta MD 50/1.4: both lenses are very similar. Flange focal distance is 41.9mm for Canon and 43.50mm for Minolta. Both are from the last product lines of the pre-autofocus era. Both were in production at the same time. Both have the same schemes – 7 elements in 6 groups, ‘planars’. Both even look similar. Prices on auctions are very close.. Etc. OK, let’s do the comparison

Shootout: bokeh – circles of light

Collection of samples with light circles in bokeh.

This test is not enough to understand the differences in bokeh between different lenses. But some examples can be useful.

Tests conditions: lenses were focused on to minimal distance, lights were fixed in more than 200m. The position of the camera did not change. All pictures are taken from the same position.

All shots have been taken with apertures from fully opened up to F5.6 (or F8 once). ISO 400. Shutter Speed – depends on light (camera A-mode with exposure compensation), WB – fixed and the same for all shots. SteadyShot – OFF. ARW files have been converted in Capture One without any correction, resized to 1200×800 and combined into diagrams.

Such scenes can’t be meet often, so this is demonstration of extreme conditions. In most cases of real life photography the blur level will be less.

It’s better to open samples in new browser tabs in 100% size for convenient comparison – all samples are clickable.

For this comparison the special photo-session has been performed. That’s why most of these samples are used only here and aren’t used in reviews of lenses. To read a reviews please follow the linked tabs with anime characters.

Additionally, I can recommend a few combinations which can be interesting for readers:
