Originally posted by normhead Thanks for the images Cannikon, I have never understood, when comparing two systems, how posting one image from one system is a comparison. People show what you they can do with one system, and assume that it's better, based on theoretical assumptions.
Indeed a single image, or single other point of information in isolation usually tells you very little. it is always important to do controlled comparisons, and keep your mind open that perhaps the difference you are seeing is not caused by the most obvious difference, but something more subtle (and often a lot simpler).
Case in point, this perspective issue. I assume many people think "When I shoot with a longer focal length on my camera I get a 'compression' effect. Since 35mm cameras use longer focal lengths they must have more 'compression'." Even if you don't have a 35mm camera on hand, there are many ways to test this theory. You could assume that APS-C is "FF" and do a 1.5x crop of that. If you did that, you would see, as my experiment shows, that, no, changing the sensor size does not change the perspective if you stand in the same spot. Keeping the same AOV/FOV, regardless of actual focal length, does not change the "compression" illusion.
It is important to know exactly what a system is capable of, both in theoretical and in practical terms, before you make any assumptions. If you see an image and think "Wow, I don't think my camera will do that" then try it. You might be surprised at what you can do with your camera.There are indeed things that a 35mm system can do that any existing APS-C system cannot do, but these things may not include many of the things you first assume.
I desire 35mm for two reasons: wide angle shallow depth of field, and wide-field astrophotography/night landscapes, both because 35mm has fast wide angles. There are no APS-C or m4/3 lenses in existence that can emulate 24mm f/1.4 or 35mm f/1.4 on 35mm. Indeed, it is impossible to get a conventional lens faster than ~f/1.1 on the K-mount because of the mount dimensions. I know these things for a fact. I have no illusions that any other kind of photography I do would be significantly better than what I can already do on my APS-C and m4/3 setups, which is why if Pentax comes out with a 35mm camera, I would get it, but I would still be using those smaller systems for everyday shooting.
And just a side note: it is an unfortunate coincidence that my username (which I use for a lot of things) is very similar to the portmanteau "Canikon" (for "Canon Nikon"), but my username is actually "Cannikin" which is something completely unrelated.
