I understand that the 56mm and the 90mm take amazing photos too but I am considering just getting a good zoom lens and save my trouble buying all the prime lens. I have a budget of around $2000 to play around and that's how I ended up with X-T1 with 18-55mm and the EM5 Mk2 with 12-40mm setup. The EM5 setup is already pushing my budget. Actually did look into the 16-55mm for fuji setup but the X-T1 with 16-55mm is way out of my budget. So now it all boils down to which mentioned setup will produce a better IQ.
Btw, I already been to fuji showroom for a number of times playing with the X-T1 and X-T10, I have to agree that the X-T1 has the best EVF at this point of time.
Well, is very hard to make decision and I know, when I was choosing between X-T1 and A7ii.
Honestly, I have seen the pictures of what APS-C and M 4/3 can do.
Put in short, M 4/3 will gain extra focal length while APS-C will have better fine details while Full-Frame (35mm) give you better Depth of field.
If you are choosing between X-T1 and EM5mk2, you may want to step down and look at X-T10 vs EM5mk2 instead. Since you are no longer comparing Apple to Apple (Any way is not fair match) but more on the pricing standpoint.
The reason for going EM5Mk2 is for the IBIS, this special feature is good to have but I personally preferred the on lens version compared to in body.
The plus point, with IBIS, you don’t need to worry which lens you are buying since the body itself comes with a stabiliser and M 4/3 can mount Panasonic lens which grant you a super large selection of lens.
The point of going with Fuji is mainly for the IQ and the colour profile. It has the most natural colour profile and the fun factor in photography LOL.
Why I suggest you to look at X-T10 is because with X-T10, the saving can be allocated for lens.
X-T1 vs X-T10 (I putting the cons first)
Cons that I noticed:
At ISO 6400, X-T10 IQ will suffer slightly (saw the image output vs X-T1 on the same lens)
Lacked of weather seal, anyway the default kit 18-55 does not have weather seal unless you going for the 18-135.
Lacked of support for super high speed card, that UHS 3 (only useful if you use burst mode)
Smaller EVF
Pros
Small body
More easy to use vs X-T1 as you have more ability to set customise buttons.
In build flash (X-T1 is external Flash to put on hot shoe)
Your call, if you want to know where is a good place to learn more between the 2 systems, drop me a PM and I tell you who and where to disturb. LOL.
