Before deciding which gear to stick to, try to get experience with different cameras and lenses shooting different subjects under different lighting conditions. Eventually you will get the feeling what you really like.
There are two big questions to answer:
Question 1: Full Frame or Crop?
Question 2: Prime or Zoom?
My current answers for my own photography:
Answer 1: Full Frame only.
Answer 2: Prime only.
Here is the gear itself:
- Film Photography
- Digital Photography
Now let me explain how I came to this conclusion, and why I did not include other options.
My goal is to get the best quality within my budget that fulfills my needs.
I am not a professional photographer, photography is not my single source of income, therefore I am not under any pressure to get the right gear for my next session or my next client. For professional photography the gear is a completely different question.
My primary genre is portrait and travel.
For travel I need something small and light that I can carry with me all the time.
For portrait I need something that gives pleasing and undistorted image with any natural or studio light. The size and weight does not matter. It should work with the wireless triggers and tethered shooting.
So, why not a crop sensor body?
Any crop will convert the focal length of the lens to something else, and the look will change from 35 mm film body. You have to do mental calculations to remember that this 32 mm is actually acts as 50 mm, and this 50 mm as 85 mm and so on. I want my results to be the same on my DSLR as on my SLR with the same lens. It will train my mind to have better visualizations.
The biggest question is a mirrorless body. Why Canon R5 did not make my list?
The EF lenses for SLR can be adapted to the RF mount, but eventually I would go after RF lenses, which are big, heavy, and costly, and will duplicate my EF lenses for SLR.
Leica Q has a fixed lens. 28 mm is a new normal. I shoot it with 35 mm fake crop. I cannot mount any other lens on Leica Q, so I do not need to worry about other lenses and spend time and money.
F/2.8 aperture is good, but f/1.4 is better for low light and bokeh.
One thing about prime lenses is that they train your visualization ability by creating constraints. Zoom lenses remove the constraints.
Phone photography shifted the standard view in the collective mind from 50 mm to 28 mm. 50 is not wide enough, does not capture a context from the short distance, and can be easily compensated by 35 and 85 combo. For street photography 35 mm is better. Leica put 28 mm on Q for a reason.
