A guy does a comparison Sigma 8-16 APS-c vs FF 12-24

JuzaPhoto - Sigma 8-16mm f/4.5-5.6 EX DC (vs Sigma 12-24 on FF)

I bet you thought there'd be more difference.

this confirms why I stay away from wide angles like these, 17-70 is fine for me: or 17 mm and above:

I am a fan of wide angle, rectilinear, perspective distortion.

I don't understand why there would be a lot of difference...they both offer similar AOVs, they are both Sigma lenses. I would expect very similar results.
Also, one would expect that FF and crop sensor differences should be very small with an ultra wide angle lens since the DOF is so big.

I thought FF was supposed to have giant advantages over APSC in the wide-angle category?

This confirms my own findings. Because of the FF-hype, and because two of my customers demanded that I shoot FF, I purchased an old Canon 5D. (MK1) And I admit, it's lots of FUN mounting my old FF Pentax glass on FF, and the viewfinder is big and bright... but there it ends. Most of my "FF" glass, even FA's, vignette and suffer from corner softness on an FF camera. (Some like that, but I can't stand it.) So I still prefer to mount those on APSC as that takes advantage of only the best part of the lens. It only lacks the big viewfinder, but even THAT is overrated imho. A new APSC mirrorless with a big bright EVF would outperform that easily.

Well, the advantage for full frame is with wide angles with relatively narrow depth of field. If you shoot with your wide angle lenses stopped down, there really isn't that much advantage, but the poster there says that there just isn't really anything in APS-C that matches the Nikon 14-24 f2.8 on full frame (of course that is a 2000 dollar lens too).

This has to be the least discussed FF thread of all time. The silence is deafening.

Well, the Sigma 8-16 is great! I don't plan on buying a 12-24 anytime soon, even with the availability of FF bodies.

While wide should be APS-C's weak spot, the 8-16 kind of nullifies that.

Having said that, I am not experienced and talented enough to have DOF at extreme wide angles matter to me. Normally I like to get close and have the composition do the talking.

Filters are a bit of an issue though. If you use a tripod you can hold gels in place.

Good point. I perhaps too easily accepted no filters with the 8-16. I rarely use my tripods.

I just never shoot wider than 15mm (that's my widest lens) or, have any desire to do so. Full frame wouldn't change that fact one way or the other. I don't like the way things look at 12mm on full frame or, 8mm on APS-C. Some of my best landscape photos have been shot in the 30 to 70mm range. There is just less perspective distortion and often it is easier to isolate a specific feature that you want to focus on.

Whatever you think of the guy he makes some valid points about how to use a UWA lens effectively!

Great you showed a guy comparing the Sigma 8-16 vs a Sigma 12-24. Isn't the 12-24 a decade old design? Most people agree that the new 8-16 is awesome. If you can show that the 8-16 wins over the 12-24 FF equivalents from Nikon and Canon, then maybe we can start discussing something. All you've shown is that the newly designed 8-16 on APS-C beats out the 12-24 on FF, and that the 12-24 is basically not worth the money.

So what are you trying to prove?

Norm is a proponent of APS-C and feels that FF improvements are nominal. I think most of us agree that with a perfectly equivalent lens the image should be exactly the same, no surprise here. The problem is we rarely get truly equivalent lenses, especially at the extremes. I think FF has its place, and if they came out with a full frame NEX I'd buy one to use my lenses as they were intended.
