Canon 100 f2?

Thinking of buying a Canon 100 f2 to use with T4i. I already have the 18-135 STM IS but I thought I would like to fool around with fast lens indoors. I would also use outdoors but the 18-135 would be my walk around.
I found one for $285 used but it's 10 years old. I haven't seen it yet but the owner says the glass is clean.
Would $285 be a good price for a 10 yr. old lens or would I be better off looking for something newer.

Consider the fact that at 10' distance with your APS-C camera, the100mm FL frame captures a tight area of 1.5' x 2.2'

The 100mm f/2 is an excellent lens. That and the 17-55 f/2.8 are my two favorite lenses to use on my 50D crop camera. $285 is a great price for the lens, and it shouldn't matter that it's 10 year old if it still functions properly.

I do question your desire to use it indoors. If you mean in your house with average size rooms, then you will probably be disappointed with how little you can fit into the frame. If you mean inside an auditorium, gym, or other large venue where you need some reach along with fast-ish shutter speeds, then it will work very well.

This gallery has a few of my 100mm shots.

...yet at 40' distance you still only frame 6' x 9' area.

I own this lens and use it in indoor venues. You'll never convince me that it won't work.

I own this lens, too! And I was not trying to convince anyone it would not work...I simply stated a fact, that at 40' the framing is still fairly tight. Merely setting expectations for the OP, that is all!

Got it.

Actually I was planning to use in my house to take candids of my kids. Wanted to try available light. If the focal length is too long indoors I'm sure I would still get good use outdoors. So $285 is a fair price for 10 year old lens?

I don't know how big your house is, but for me 100mm on a crop indoors is far too long. I'd be looking at at something in the 28-50mm range if I were you...28/1.8, 30/1.4, 35/2.0, 40/2.8, 50/1.8 or 1.4

If the family room is a good sized one, even 20' is still stretching how far back you can get (darned furniture gets in the way of you from putting your back against the wall) and at 20' distance with your APS-C camera, the 100mm FL captures a fairly tight area of 3' x 4.4'. Shooting a 2 year old might work, but if they're 6 year olds...

Indoors basketball court, easy. Indoors typical home, too hard if not in a pretty spacious home

Sorry to go off topic, but how can you work this sort of thing out.

not only that but you better have good handholding technique because it's a long lens especially on crop.

i would pay a little more and get a new copy or a near mint newer copy.

There are some programs on line or which are downloadable, which do Field of View calculations. Handy to have, for discussing hypothetical circumstances on POTN!

That is a great price for the 100/2. I paid about $330 for mine and considered it a really good value.
