I was a bit underwhelmed by the two kit lenses that came with my Sony NEX 5R. The SELP1650 I sold but the SEL55210 I've hung on to because I just didn't know what to get as a replacement. I didn't want to spend grand or more on a telephoto lens, neither did I want something too bulky. So what to get? I had bought Canon's FD lenses (35 2, 50 1.4, 85 1.8, 135 2.8) and used them with a dumb adapter with very good results, but none of them reached far enough.
So I went on numerous forums and review sites to find a lens that can conquer the SEL55210 without breaking the bank, or the bulk!! The Canon FD 80-200 f/4 L kept popping up. It has quite a big fan club with pretty much everyone saying its sharp wide open, minimal CAs, flare, etc. But I couldn't find any definite tests. No comparison between lenses, MTF tests (I know this is asking a but much now), etc. Anyway, because of the overwhelming positivity towards this lens I decided to get it. 250 USD later I had a mint condition Canon FD 80-200 f/4 L at my door.
I've had the lens for a month and now it's time to share test results. Here's what I did:
- I shot each lens at max tele only. First both were wide open then I stopped the Sony down to f/8.
- I shot a target about 5 m away from the camera and manual focused at each setting at least 3 times and then selected the image with the best focus when looking at the files on my large monitor.
- I set OSS off, used a table and a 2 s delay when shooting. (Actually, come to think of it I should have used my remote, damn I never use that thing!)
- I shot in RAW, ISO 100 with +0.7 EV since the NEX 5R tends to underexpose by this much and then imported these into Lightroom.
- I equalized white balance
- In terms of sharpening I tried to pull out as fine detail without going overboard so I used sharpening amout: 99, radius 0.5, detail 0, masking 0.
- I left the default color noise correction on
- I made no other changes (unless Lightroom makes others I'm unaware of) and exported into JPEG at 90% quality
So how does the Sony compare to a Canon lens that was designed a quarter of a century earlier?

Have a look at the images yourself to decide how they perform.
If you need a second opinion here's mine =)
Sharpness: From what I see the Canon at f/4 performs better than the Sony at f/6.3 in all regions of the image (I know that most of the image is out of focus but you get what I mean). At f/8 the Sony seems to sharpen up and is on par with the Canon in the center but further out the Canon is still the clear winner. To be honest it's hard to tell if the Sony actually sharpens up in the center when stopped down or if the change is just perceived due to the increase in contrast and reduction in CAs. It certainly sharpens up further out when stopped down though.
Contrast and CAs: With both lenses wide open the Canon is the clear winner in both regards. In fact it's remarkable just how good the Canon is here in both areas! With the Sony stopped down to f/8 they are about on par. I'll let you decide this one.
Bokeh: There was a reason I left most of the image out of focus with an annoying wood column on the right - it was so that some comparison of bokeh can be made. Obviously the depth of field is much narrower with the Canon especially when compared to the Sony at f/8. In terms of the quality of the bokeh I'll let you make up your own mind. Of course bokeh is a peculiar beast and depends on focus distance, background distance, aperture, etc. and the same lens can create relatively smooth bokeh at some times and then very distracting and ugly bokeh in other compositions.
Anyway, I'm no pro so I'll leave it at that. I just hope this helps others get an idea for what each lens is capable of. Interestingly the lenses cost about the same to buy if you buy the Sony new. The Sony gives you AF and OSS. The AF can be handy of course, but the OSS is somewhat negated by the fact that you have to stop down to f/8 to get a similar performance to what the Canon gives you at f/4. So ultimately you only get about a 1 stop advantage due to OSS (I'm working on the assumption that OSS in this lens would normally give a 3 stop advantage). Of course this has only been a comparison at around 200 mm.
Other things to consider are size, weight, zoom ratios, macro abilities, etc.
Finally here's a bit more of what the Canon can do...

Can you pick a winner??

P.S. My first post here so excuse any newbie/noob mistakes!
