OK, I am trying to understand the difference between Full Frame and APS-C. I have a Canon T6i and would like to better understand lens selection
Many thanks

APS-C cameras have a smaller sensor than full frame. Canon lenses with the EF-S designation are designed for the T6i and related (I have a T3i).
But you can also use the Canon EF lenses on the "crop sensor" (APS-C) cameras. I have a Canon EF 70-300 mm.

We have fixed focal length and Zoom lenses. They are available to cover wide angle, medium distance and distance (telephoto) So, Neil what do you want to take pictures of?

Stan, you missed Neil's first sentence. There are lenses that fit both APS-C and full frame cameras, but there are lenses that are only for APS-C. Important to know the difference between sensor sizes for this reason.
I used an APS-C Canon for four years before I learned there were cameras out there with larger sensors

It is confusing with the myriad lenses available. As far as Canon is concerned (Other makers have other designations) EF-S lenses are designed for A-PSC (crop sensor) and ES lenses are for full frame. Full frame uses a 35mm sensor (Lke the 35mm film cameras) and the crop sensor is just that. It uses a smaller (cropped) sensor. It has little to do with the quality of the image. EF-S lenses must be used on Crop sensor cameras ONLY wheras ES lenses can be used on full frame as well as crop sensor cameras. Hope this helps.

These graphics may help. And I'll let the more familiar Canon users explain the different Canon lens mounts that you need to know about.

If we use the Nikon example the crop sensor camera has a 1.5 factor while the Canon has a 1.6 factor. The lenses for crop sensor cameras then only have to cover the smaller sensor. They can be smaller, lighter and less expensive. If we put one on a full frame camera the photo will be the equivalent of looking through a peephole. Just a round picture with black sides. If we put the full frame lens on the crop sensor we'll just capture the center part of the light coming though the lens.
Lenses are rated based on the 35mm camera therefor when we put a 50mm lens on a full frame it's 50mm but if we put it on a crop sensor it's the crop factor times the mm so it's 50X1.5 or75mm.

Thanks for the replies, yes it is a bit confusing. My main interest is general photography and some macro. I have an 18-135 IS USM kit lens that also does macro. I would like to add a 50mm?? prime lens that will not destroy my piggy bank. It does not need to have the Canon label on it.

Cool post and very informative. Bravo!

Now that is interesting, so if I add a 50 mm lens to my Canon T6i it really is a 75 mm lens. Oh for the days of my old Nikon F3 when it was what you see is what you get.

NOPE. The focal length does not change.
On your Canon T-6, you would get the equivalent field of view as an 80 mm lens on a full-frame camera like your Nikon.
50mm x 1.6 = 80mm
For a Nikon DX camera, since it has a slightly larger sensor than your Canon T-6, a 50mm lens would have the equivalent field of view a 75 mm on a full-frame camera.
50mm x 1.5 =75mm.
-But it will always be a 50mm lens no matter what format camera you use it with.
Unless you need to know this stuff for technical reasons, just look through the finder and fuggedaboudit.
You still get what you see through the viewfinder, you're just using a smaller part of the image because of the smaller sensor.
Archernf, in your film days, did you ever shoot with a format bigger than 35mm?
If so, just think of it a different format than 35mm (which it is) but you are still able to use some of your 35mm lenses with it.

Nope , just 35mm......in fact my very first 35 mm was an Argus C-3 (a relic) but then I am dating myself...............
