I have a 10-year-old Canon Rebel T3i with a 100mm macro lens and a couple of Canon Speedlite 270EX II. However, I'm interested in upgrading to a newer version. I believe I want to switch to a mirrorless and full-frame camera.
Can you suggest any models that would be a good fit for me? Also, I'm not sure if getting an adaptor for the lens would be worth it, or if it's better to change the whole system. What do you think?
One option would be an EOS R8 with an RF 50mm f/1.8 lens. That would do very well in lower-light conditions. Total would be around $1,700 leaving a decent amount left for a flash.
My thought with this full frame camera along with a standard lens, is that would result in images pretty close to what the human eye sees. The minimum focusing distance would be 11.8 inches, so you could get quite close.
Another option though, in case you need very detailed images, is with a Macro lens. The RF 100 mm f/2.8L Macro though is $1,400. So you'd need to go with a cheaper camera body; probably something like the EOS R50. Though I don't know what would be more beneficial to you: a cheaper crop-sensor camera with very good macro lens, or a better camera body with decent standard lens.
I'm not exactly sure what the best flash would be for the EOS R8 as there are some issues regarding compatibility. Will let Demetrius weigh in on that to see if an EL-5 would work (cost is $400).
"I'm not exactly sure what the best flash would be for the EOS R8 as there are some issues regarding compatibility. Will let Demetrius weigh in on that to see if an EL-5 would work (cost is $400)." All of Canon's EX or EL speedlites will work on the R8. The R8 supports automatic brightness adjustment of the LED AF Assist Beam on the EL-5. The speedlite won't switch to Intermittent Flash Firing unless it gets too hot. During LED AF Assist Beam projection. The R50 requires the AD-E1 hot shoe adapter. That camera lacks the normal communication pins for older speedlites. All other multi function shoe cameras have these pins such as the R8. The OP's existing 270EX II will work if there not updating it. The EL-5 works very well.
I think the front of the lens would be around 8 inches away from your patient (the focusing distance is measured from the actual sensor within within the camera). But it sounds like you'd be better off with a macro lens.
The EOS R8 with RF 100mm f/2.8L Macro would cost $2,900. Not sure if your budget is flexible, but this would be an outstanding combination.
The only cheaper cameras in the R-Series would all be crop-sensor cameras. All prices below are with the above lens:
I was looking at the RF 100mm Macro too. Since the OP mentioned a lens for up close work.
As Demetrius mentioned, knowing your budget would be extremely helpful.
I would definitely recommend Canon’s R-series. While there is an RF 100mm macro lens, depending on your budget, you could start off with an EF to RF adapter (strongly recommend purchasing Canon-branded adapters). Then over time, migrate to RF lenses.
I like Ricky's first suggestion. R8 with RF50mm f1.8. Pair this with a tripod and some portable studio style lighting. You might not even need a flash. I just purchased a RF100mm Macro from Canon a few months ago. I purchased it refurbished. It was under $1k
If you don't have the room to dedicate a chair to camera/lighting set up, I understand. In that case, a flash might be better option from a portability standpoint. Plus most of your patients are probably wearing a dark pair of lenses for eye protection any way. 😎
The T3i and any of its lenses, dump them. Donate to a deserving family member, church or school.
