Hello!

Bought my first SLR a month back, and I love it! A whole new world of photograpy and equipment appears.

I still have probems to understand everything about the differences between FF and 1.6 sensors and lenses.

Will a FF camera with a 17mm lenght EF lens take similar pictures as a 1.6 with a 17mm EF-s lens?

Ok, the pictures of the FF will be bigger, because of more pixles, but will the perspective/angle/view be the same?


Thanks in advance.

17mm on a 1.6x body will have the same FOV as 28mm on FF, EF-S or EF, doesn't matter.

No. The FF will be wider; a 17 mm lens always takes essentially the "same picture" in perspective and magnification, however the smaller sensor of the APS-C captures less of it than will a FF camera. The focal length of a lens merely describes how far away from the lens the image from an infinitely far-away object (like a star) will form and says nothing about the angle of view that lens can cover.

Don't get bogged down with this. It's too soon to worry if a lens you don't own would perform differently on a body you don't own. Go with what you've got. In fact, you can pretty much forget "FF" and "1.6" altogether. If you must, come back and ask the question when you've taken 5,000 or 10,000 frames

These are just benchmark terms for those of us old timers who are moving from film, to give us a rough idea how our old film lenses will perform on a digital camera. Since you never used a film SLR, you don't have (nor do you need) that point of reference. As Olympus might say, you have no "legacy issues"- be grateful!

The whole beauty of SLR's is that you don't need benchmarks, yardsticks or formulas to compose your picture - what you see is what you get.

Thanks.

I knew about the 1.6x factor of the focal lenght.

Belomodos picture/drawing makes me understand. I bigger picture is also wider.
