Hi Slobodan,
For Sm, online and prints up to 16x20, I think the RX-10iii (and, my guess the iv, too) is ideal. I can confidently shoot most subjects and can carry the camera all day with no fatigue. The all-in-one 24-600mm f/2.8-4 Zeiss lens is really the ideal, in fact, perfect, walkabout lens. The stabilization makes the everything up to 600mm possible, even with ridiculously low shutter speeds at 600 (1/50th!)
Places you will notice a difference . . . Shooting:
- action: fewer keepers compared to a DSLR; that being said, still enough keepers to be productive
- birds on the wing: I find it almost impossible to track and shoot successfully compared to DSLR
- some edge distortion and softness, but no worse than many DSLR lenses
- close-up and macro: extra care must be taken to zoom and focus; not as intuitive as with a DSLR
In processing . . . note: I mostly shoot raw, especially for my personal work - and the files are excellent (even the jpegs are excellent and can withstand some processing)
- sharpness (or ability to be sharpened) is excellent, especially at ISO64 to 125; at 200 photos start to look a little grainy and by 400 they are grainy, but still, definitely printable and perfectly fine for the web/projection
- shadows do not recover as well as I would like them to; increasing “Shadow” adjustment on Lightroom tends to brighten mid-tones too much without doing as much to shadows as I am used to with Nikon NEFs
- you will not have as much highlight room as you’ve been used to
- smoothness: you may miss the smoothness of tones that FF produces; although I must admit, on web/projection the difference is virtually unnoticeable; on prints, it would take a side-by-side for a medium-sized print at normal viewing distance to really see a difference; larger prints, well you know what happens; 20x30 - I’ve not printed that large with the Sony, but with a good file and proper up sampling, I’m sure it would look great.
The Sony is the ideal travel camera as it’s the camera that can always be with me (Though the same can be said about my iPhone!). I still use my FF for fine (serious, aka 4x5-style) landscapes (when I’m not travelling overseas) and an APS DSLR for wildlife, birds and sports, again when I’m not travelling overseas. My travel photography is for a market that doesn’t usually require large prints, so the Sony is ideal. It’s also my go-to camera when I’m out hiking for a few hours, but even then, I’ll often use an iPhone and I know yoiu’ve had similar success with that, too.
I hope this helps,
Terry
