I find myself coming back to this thread regularly as I am at that stage of working out what I need, rather than what I want. I recently invested in the X-T4 with 16-80 kit lens and got the camera bag (Lowepro Flipside Trek 450 rucksack) that suits my needs perfectly. The carrying capacity of the camera area of the bag is fairly limited, and covers the camera, filters, flash unit and around 3/4 average sized lenses. Now, I am not 'unnecessarily restricting myself' by limiting myself to 3-4 lenses - I could buy a bigger bag and raid the magic money tree to get any lens I want but I think this is a very valid exercise in affordability and compromise, but still being able to achieve what you want.
At present, I have:
- 16-80 kit lens
- 35mm F2
And top of my list to get is the 80mm macro lens.
I have also been looking at what zoom lens to get. I love macro photography, hence my first choice of lens to buy is the 80mm, but as a secondary photography interest I like landscape and wildlife photography in equal measure. This leaves me in a bit of a quandary as the better landscape zoom is the 10-24mm, whereas for wildlife I would be better off with the 100-400mm. Maybe I can squeeze the camera and 4 lenses in my bag
Edit: I have been doing more research on telephoto lenses and discovered that the 70-300 will be a far better fit for my needs, budget and restricted space - it is a much smaller and lighter lens with very good quality results and will be a seamless fit with the 16-80mm kit lens.
