I just dont see any apeal of buying legacy lens. With adapters you are still not getting small size,
Depends on the Adapter. Leica M, L39, and Pen F all are very small adapters.
you lose autofocus, flexibility of a zoom.
Who says you can't get a manual focus zoom? Granted, the quality of the modern zoom is likely better. Autofocus isn't important for many shots. I can focus manually quickly, and for slowly moving subjects or static subjects you just don't need AF.
And please prove me wrong by showing compared photos, but i havent seen any noticeable quality improvement (we are talking sub 150-200USD, 1855 price on ebay) from the popular legacy glass i see every day on this forum. Sure, you get wider apertures, but 18-55 has OSS, which gives 4 stops...
Say it really gives you 2 stops, it doesn't give you faster shutter speed which you often need. The only thing it helps is that you don't have to carry a tripod for those situations. If you are photographing a person you still usually need a faster shutter speed so OSS isn't that helpful in those situations.
The main benefit is aperture. This 42mm f/1.2 lens I am playing with has about 4 f/stop advantage over the kit lens at the same aperture, and that is 4 f/stops faster shutter speed so you can stop motion, etc, or get very shallow depth of field. The kit lens can't have that option. The OSS is nice, but again, doesn't give you shallower depth of field or faster shutter speeds.
The 50mm f/1.8 and 24mm f/1.8 are AF lenses for those that want the experience of large apertures, but still maintain AF. If you shoot at f/5.6 you aren't going to see that much different between the lenses. The issue with the primes is they are relatively expensive. An old manual 50mm f/1.8 with adapter is about 1/6 the price of the new 50mm f/1.8 OSS and won't perform that much better. If you don't need the AF the old manual lens is nice. Size wise the adapted 50mm probably isn't that much different in size than the new 50mm f/1.8, that thing is pretty huge.
