My understanding is that there is no way to adjust the 20d. Does that mean any lens that would require this will not be as sharp? I've had people look at my photos and say they look soft. Of course they are handheld and I haven't tried any real testing with a tripod.

The reason I ask is I'm looking at a 70-200 and was going to rent a sigma and canon but can I get a good comparison with the 20d?

I know people have mixed feelings about third party lenses but I know there are pros that use them so they can't all be that bad. But maybe I need more education on the topic

Heya,

Right, there's no MFA on the 20d. But that's not going to fix any problem, it can just help with a consistent problem. If the lens severely back focuses/front focuses, you're in for a problem.

There's a lot more to sharpness than simply adjusting focus. It could be your shutter speed, vibration, lack of IS/VC/OS, being handheld. Since you say you have no even tried with a tripod yet to rule these things out, and literally just look at it's ability to focus without vibration in play, I say you try that first before you worry about anything. So get on a tripod, focus with autofocus, and try with manual focus. Use a timer or shutter release so that you're not touching the camera when it fires. If the images are pretty sharp, then it's not your camera/lens, it's just your use.

I'd look into the EF 70-200 F4L IS or the Tamron 70-200 F2.8 VC. Similar cost range.

But test on a tripod before you buy. And buy from a place you can easily return it.

Very best,

You should still be able to get sharp shots without MFA unless there is a significant mismatch between the body and the lens. If that is the case, you can always have the lens calibrated to match the body, which does the same thing as MFA but needs to be sent in to be done by a technician, rather than doing it yourself.

People were getting sharp shots before MFA became available, I myself used a 20D for several years and got sharp shots from it with all my lenses, with the exception of the 28-135mm (which wasn't a good lens) and that was solved by replacing it with a 24-105L which sharpened things up nicely.

I see that you list the 75-300 amongst your lenses, that has a reputation for being one of the worst lenses Canon have made, and is likely to be soft unless stopped down to a small aperture, MFA would be of no help there. Replacing it with ANY 70-200 should show an improvement in quality.

As mentioned above, there are many, many possible causes for shots to be slightly soft though, so it is as much down to good technique as good glass. I have had three bodies without MFA, and have several lenses and got sharp results from all (apart from the 28-135) so MFA isn't a necessity. Indeed, I now have a body which DOES have MFA, yet I have never felt a need to fiddle with it. I'm not saying that there aren't combinations of individual bodies and lenses that don't work well together, and can be improved with MFA, or even cases where MFA has been useful on all a photographers lenses (perhaps the body was at the edge of tolerance in one direction and there lenses were all centred or on the other side). What I am saying is that lack of MFA shouldn't mean that you can't get sharp shots.

I have arthritis and couldnt take clean shots without image stabilization. It just cant happen for me. I sold the 1D MK III and the L lenses long ago and recently went back to DSLR with a nearly NIB NOS 30D and I went ahead and got the STM version of the 18-55 IS and 55-250 IS and I couldnt be happier. You dont have to go pro to get satisfactory images if you arent selling them for a living. Image stabilization has made photography possible for me again.

I might not have updated my signature but the 28-80 and 75-300 kit lenses have pretty much been retired. I keep them with my film camera.

Right now I have the 17-40 F4, 50 f1.4 and the 85 1.8 canon lenses. I like them all.
For me, it seems anything over 400 ISO has a lot of noise. I was taking pictures of a friend, engagement type photos, in the afternoon and it was a lot of shade so I had to use a slow shutter speed. It's not so much my hands, but more like I sway when trying to stand still and I get some blur. Maybe I should try yoga.
I do plan on this being a career so I want to get good equipment.

Thanks for the info.

I have lenses that required a bit micro focusing on my 50D spot on on my 20D and 700D.

Hi, :) If you post a photo of what you mean by soft maybe someone can help.I have the non L 75-300 lens and if the photo is sharpened up afterwards it is plenty good enough.
I "think" Canons default to quite soft images anyway-happy to be corrected if wrong.
Is the problem mis focus or just soft?

Nothing wrong with 1D MK III, problem is arthritis. 1D MK III with L lenses too heavy.
