Canon t5 to SL2?

question is weather moving forwsrd or laterally would be better. Some of the older Canons are down almost to the level of the new entry level ones.

Start by analyzing exactly what it is you need to gain. And what you are willing to give up.

If you are considering an older full frame body, is it higher (clean) ISOs that you need most? Are there other work-arounds available to you? Such as using a tripod, or utilizing image stabilization (you don’t mention which version Tamron you have). Can you use another flash to light the background? Can you use more available light? Do you shoot RAW? How good is your post processing? Do you have effective noise reduction software? Do you mind spending the extra time doing PP? Might you benefit from Multi Shot Noise Reduction mode?

With FF, keep in mind that you lose the crop sensor’s extra “magnification.” If you are into true macro, you will then have to move closer to your subject (and focus closer), thus losing both working distance and a full stop of light. You’re probably pretty darn close with the 15mm macro already! Plus half of your ISO advantage just disappeared (when shooting macros). You might try using the Raynox DCR-250 (+8 diopter) close up lens on your Tamron to increase “magnification” (it acts as a doubler, but doesn’t lose any light in the process, only working distance). Remember too that you will lose use of your 55-250 (on a FF body).

I shoot a Lot of macros, and have always felt that (for the macro shooter), the benefits of a crop sensor outweighed the benefits of FF. HOWEVER, if you are shooting a lot of close-ups (in low light), then the cleaner ISOs of a FF may indeed benefit you more.

This is only scratching the surface, and there are a ton of other considerations regarding your upcoming choices. You’ll need to do a lot of soul searching in the meantime. Know Thyself!

Best of luck,
