Will IQ drop if I attach an adaptor to take other lenses with different mount?
What do you think ? expensive Voigtlander close focus adapter and Voigtlander 50mmF1.5 asph M mount on A7
Same lens wide open @ F1.5 and close focus wide open
That's going to depend on the individual lens characteristics. Older lenses with less contrast and a tendency to flare will perform with less apparent IQ than modern lenses. Some like the "softer" look and go after older "legacy" lenses. One thing to look out for is attempting to adapt Canon EF lenses to bodies that cannot electronically control the aperture. Micro Four Thirds bodies especially.
Those adapters that are advertised to offer either electronic aperture control or an aperture of their own are often very expensive or may not work as well as advertised.
IMO the best overall solution is one of the Micro Four Thirds bodies and the fairly extensive selection of "native" Olympus m.Zuiko and Panasonic Lumix lenses that fit them. If still photos are what you're after the Olympus E-M5, E-M10, or E-M1 may fit the bill. If you are looking at motion picture (video) the Panasonic Lumix GH4 is king "hands down" and also does a very creditable job on stills as well. The GH3 is a very good buy at lower cost but the EVF in that model can be problematic. The GH4 solved that issue.
I have an Oly E-M5, Panasonic Lumix GX7, GH3, and GH4. I have a couple of Nikon F mount lenses but much prefer the "native" Micro Four Thirds offerings by Oly and Panasonic for their very much superior IQ.
4/3 sensor is 178 sq. mm
APS-C sensor is 329 sq. mm
So the difference is 151 sq. mm. That means APS-C sensor is 84% larger. Not exactly "negligible".
Gsgary & Bif thanks for the feedback
Just bought an Samsung NX30 for £800 , but Samsung has an old camera trade-in and you get £200 cash back at the moment in the UK, I have an nice 6 year old Canon A590 for them.

X or NEX, also. I wouldn't even consider Nikon. I think it's a pretty dead platform for one, and second smaller than APS-C has advantages, it's not going to mean anything unless you're either into experimenting with strange lenses or need very long telephoto lengths.
I recently got an XE1, and have been extremely impressed by the Fuji sensor shared with the rest of the X-pro cameras.
Well, yes and no. These are more qualities of the older lenses than the adapter. So long as the adapter doesn't have internal correcting lenses (i.e. speed boosting or SLR adaptors for shorter register) then there is no perceivable reason why adapted lenses would perform worse.
Some rangefinder lenses with significant retrofocus may behave oddly however due to that the sensor cannot detect light as easily at a severe angle.
