Hi, I apologize for my noob language in advance. Basically my wife is a dentist and currently using Canon 1300D + EF 100mm f/2.8L Macro IS USM lens + Canon MT-24EX Macro Twin Lite set-up to take a close up patient's teeth photos. It is a bulky and heavy set-up as you can imagine, but was working fine so far.. Except it was lacking some more details and clarity on the photos when you zoom in. Which she realised is kind of crucial. So I bought Canon R. So I have 2 questions here: 1) Is this still a relevant set-up to use same lens + flash mentioned above for taking macro shots With Canon R? So far she was told to use 100mm lens because if you use smaller ones there is a visible image distortion (which is a big issue in this case, image has to be as close as possible to real one) and also you have to keep lens much closer to the object (mouth in this case). Is this still relevant to full-frame mirror-less camera? Can she get away with equaly good results using smaller Canon RF 35mm f/1.8 IS STM Macro lens + same flash if you adjust settings? 2) Second question is just for general use, since we did not buy any lens for Canon R yet. We have just standard kit 1300D lens I believe it is 18-60. Will it be enough for travelling and casual 'any situation' photos or would you recommend to go for R's offered RF 24-105mm f/4 IS USM lenses? Thank you in advance.
