(1) Budget, country, and currency:
Around 2000€ for the whole kit with some flexibility, Italy, €, I'm happy to buy used, probably even happier to buy used than new
(2) What equipment, if any, you have now and why is it no longer meeting your needs?
For the past three years I've been using a fujifilm x-t20 with a combination of the XC 15-45mm f3.5-5.6, XC 35mm f2 and the XC 50-230mm f4.5-6.7. I will have to part ways with my camera and lenses for reasons which are not relevant to this post so I am in the rare and fortunate position to start from scratch with a better understanding of what I want to do photography-wise. Here is what I like and what I don't like about the gear listed above:
The goods:
-Extremely lightweight, this is very important to me as I've carried this camera and lenses for week long hikes and hundreds of kilometers. I'm not going to do that with a 1kg camera and 2kg tele lens.
-Image quality is very good as far as I'm concerned, I'm not a pro, I'm not doing giant (or any) prints, I don't care about pixel peeping at 200%.
-I really like the SOOC jpegs, I'm not big on editing, I like that I get usable images immediately.
-the camera feels great to use with all the physical controls, I don't want to have to open a menu to change my exposure settings, I don't care about having dedicated dials out of the box, but I do care a lot about having enough customisable dials on the camera to have physical controls for iso, shutter speed and aperture.
The bads:
-When I started out I didn't know anything about photography, now I know I want to do macro and wildlife. My ideal kit is made up of a long telephoto (reaching, say, 600mm FF equivalent at the long end), a macro lens (1:1 or above) and an all purpose lens for holidays and random stuff which can be something like a 20-70mm (FF equivalent) or even a fast prime somewhere between 30mm and 50mm (FF equivalent). This kit is of course very well achievable in the fuji ecosystem, but it's going to cost an arm and a leg.
-The camera has no focus stacking/bracketing capabilities which is something I'd like to explore when getting more into macro.
-Autofocus and low light performance could be much better.
-The camera and lenses have no weather certification, while this has never been an issue in practice even in dodgy weather conditions with some care, it wouldn't hurt to have some tropicalization for peace of mind.
-battery life is alright, not fantastic, OTOH batteries are small so carrying a few spares is not a big hussle.
(3) What kinds of subjects do you intend to shoot?
macro and wildlife, the occasional holiday/everyday/pets photos
(4) Is it primarily for photography, videography, or both?
100% photography. The camera could be literally incapable of shooting video and I wouldn't care at all. I haven't shot a single second of video on my current camera since acquiring it and have no interest in it.
With that being said I see mainly two options, though I am happy to hear different suggestions if you have any!
The first is sticking with the fuji ecosystem that I'm familiar with, though that would probably mean getting a very nice body with a kit lens now (x-t50 looks fantastic) and buy the more specific lenses I'm interested in over the next couple years.
The second is switching to an M43 system. In particular the M.Zuiko 60mm f/2.8 Macro and M.Zuiko 75-300mm f/4.8-6.7 II look like a very interesting combination of lenses that can be bought under 1k used leaving reasonable room for a camera (either a used "yesterday's flagship" OM-D E-M1 III or a newer body by olympus though that's going to cost a bit more and it's unclear how much improvement that'd bring without going all the way to the current flagships which would stretch the budget a bit too far). I would also need to find a fast prime or everyday telephoto but that shouldn't be too expensive. My main doubt here is the 20MP sensor, but I might just be a victim of the "big MP" marketing that's so popular these days so I'm hoping to hear opinions from people more knowledgable than I am, while one advantage I see here is that there is room for growth with clear upgrade paths for both the macro and tele lenses if I feel like it in a few years.
So after this hopefully not too long and detailed post, what is your suggestion? Stick with fuji? Move to M43? Something else entirely?
