Just a Simple Question About Dynamic Range

Heh.

Actually, I think the IQ of current rebels is so close to that of the 7D that the difference doesn't matter. The 7D's high ISO performance is just barely better than the T4i's. The difference was visible, yes, but barely so.

Yeah look at this:

Choosing for example ISO 6400 in a Canon 1100D (T3), 7D, 60D and 500D (T1i). Noise is higher in 500D and lower on 7D but there isn't that much of a difference.

1st. Thanks everyone for your discussions on dynamic range. This has been a very informative and educational post. Probably one of the best I have seen in a while.

To KenjiS. What about the Canon 20mm f/2.8 USM? I don't know anything about this lens so not sure of it's quality. Sure it's just a bit wider than 35mm (@ 32mm) but you can crop into the image. I do agree with you tho. I missed being able to look through my view finder and see what I expected to see on a 50mm when I had my 50D and other than high ISO noise it was a major reason I went to the 5D. But you are right, there is something about film and the feel and look it produces. I guess that's why I still shoot film too haha.

Glad I can help

On the 20mm f/2.8, its not that bad optically on a cropper from my understanding, but the MFD is a bit long (MM is 1:7 or so) versus the 1:5:5 on a 35mm f/1.4L.. the Sigma 20mm f/1.8 is a closer fit (1:4 MM) It sucks in the corners on a FF body (But then again, I'm not using a FF body! its VERY good in the center which is all my 7D would use!) and its a consideration.. I love the "exaggeration" a wide lens gives when shoved up close to a subject...

Option 1 is i get a FF body and just enjoy my 28mm f/1.8 even more, Option 2 is i just get something wider on my 7D a 20mm f/1.8 or a UWA zoom for instance...

But anyways, At one point I had discussed how i liked some of my film shots and folks here said it was likely just the way lenses behave on full frame.. None of my old glass was really "Special" (When i shot film i ran the 15-30, 50mm f/1.4 and 200mm f/2.8L) I kinda miss my 15-30.. the only reason I havnt picked up a 8-16 is because I keep wobbling on the full frame fence...

You really should just get the 8-16 and see how you like it. I think you'll be very impressed as long as you get a good copy.

For instance, I took this while standing underneath the tree:

Right. So lenses play a part as well. Interestingly, if you had an APS-C sensor that could oversample - perhaps getting to the 24MP resolution level, and you had the lenses to do it, you could do away with the A/A filter entirely. That also happens to be a number that often pops up regarding rumors of a 7D mkII. Also, the delayed development of a new sensor for the 7DII has been rumored to be the cause of the unprecendented 2.0 firmware update that recently came out. The aggressive AA filter is a big gripe of many 7D owners so it leads me to wonder if Canon doesn't have a new trick up its sleeve soon in releasing the 7D replacement with a 24MP sensor that does away with the AA filter entirely. WIth dual digic 5 processors that would be able to put out about 10 fps. That also happens to be just the camera it would take to pry my 7D from my fingertips.

Now THAT would be an interesting upgrade!

i use a pretty simple method: when dealing with supersaturated colors in the subject, underexpose so as to not clip single channels. i usually go about 1/2 to 1 stop.
