Does this lens maintain sharpness when stopped down to f22 and f32, or does it start to soften?

I use it almost exclusively to shoot macro, so the center is sharp and then the dreamy bokeh! I don't know if this helps but it's all I know.

This is the sharpest lens I own. But it does not have image stabilization. So I generally use a high shutter speed even when I'm on a tripod. So I find using high f stops a very rare event.

I felt the same way when I got mine. It definitely has more resistance than the 18-55, but I think it's by design. With a more shallow depth of field at f1.2 you want a tighter focus ring for better control. Whether yours is abnormally resistant I don't know.

I had the Tamron first. I got it because it had good reviews, a lower price, and IS. Bottom line: it was very soft and had AWFUL back focusing issues over 50 mm. I sent it to Tamron for calibration and it came back worse. I ended up returning it and instead of getting another copy of the Tamron, got the Canon. Best decision I ever made. This is the sharpest lens I own, including all my primes. I was told by Tamron that 20% of their 24-70s have focus issues on the Mark III (which I have) due to the Mark III's focusing system and the Tamron not being totally compatible with it. I have a 60D as well and the Tamron also had back focus issues with that body as well, although slightly less. I would not hesitate to recommend the Canon, bar none.

I don't generally use RAW settings, so I'm not entirely sure, but I don't think it does, as this lens is entirely mechanical. You have to adjust the aperture manually, and the lens only has one focal length with manual focus.

Hello Mike, it is an f/4G so los light conditions will always be an issue. Having said this, I can tell you theta I love this lens. It is very fast in focus and extremely sharp. In dark enviroments such as weddings or concerts you may have to put up your iso setting a bit and get a little noise on your images but again, sharpnes will do the work and have a little noice images in dark enviroments sometimes is good. If you use flash you have no problem at all. I hope this helps a little on your choice.

Yes it is if you can deal with the small f stop. At f/5.6 or f/8 the lens is very sharp.

Yes, typical of most macro lenses.. it will have "soft edges" I find that it is a good lens for well lit subjects and I either leave the soft edges because I like the look, or crop it out if it is too distracting.

I have shot 3 weddings with this lens and I haven't had a problem with it, it's been great. I have used the 70-200 and its just a bit faster that the 80-200 but I can't really tell the difference.

It is a great lens and takes sharp shots. The only thing i done like about it is the aperture. only opens to f/8, not great for low light conditions

I used 28-135 for more than 8 years and was happy with it. Recently, I purchased 24-105 and I was very surprised. AF is fast, image is clear, IS is working very good. 24-105 is excellent lens and much better than 28-135.

Depends on the lens, but usually it causes only about a 1/2 stop decrease in light. It doesn't degrade image "Quality". Although you may run into vignetting(again, depends on your lens and camera type).

It's a very good, an excellent lens for low light shootings. It's manual focus , and on f 1.2 it's quite soft, though you can find the point of sharpness on the photo, but from f1.4 it starts to be sharper and more interesting! Happy New Year)))

I don't have issues with lens creep at all. I've owned it for a couple of years now. It's on my camera 90% of the time.

I don't recall which one I got, but the picture quality is very good for this lens. The picture stabilization on/off button doesn't show any noticeable quality improvement for me. Need to keep checking.

Don't know -- but I do know it does not stay sharply focused at higher zoom levels after about 1 year of regular use. Never dropped the lens or treated it rough. Just noticed the sharpness disappear after a while. Very disappointed in this lens!

Mine only decreased approx. 1/2 stop of light. Using Nikon D3200 body with Rikenon 50mm 1.7 lens. Quality was not 'degraded', thought images are a tad softer.

It performs well in low light, sometimes throws a shadow, but I think that is my inexperience as a user. Wonderful lens!
