Some testing notes:
Shot on tripod, IBIS off, manual focus, 5 second delay, A7rII, RAW, same exposure, all lens' corrections turned off, no editing except balance of WB.
1) Infinte crops: Tamron @ 20 vs. G 20
Finding:
The G 20 is better at each comparable aperture across the entire frame. I like the G 20 1.8 to the Tamron's f8, all over the frame. This is impressive.
Finding:
GM 24 blows the others away wide open. At comparable apertures, I prefer the GM 24 > G 21 > G 20 > Tamron
3) Color and Fine Texture:
Contax G 21
Tamron @ 20
GM 24 @ 1.4
G20 @ 1.8
Finding:
The texture and color the GM 24 is easily differentiated from the G 20--look at the aliasing on the G20 and crispness. The closest to the GM 24 is the Contax G 21 with similar saturation and textural quality. Note the paper texture more on the Tamron and G 20 (sharp, no SA!)
4) Framing
G 20
Tamron 17-28 @ 20
Finding:
G 20 is wider, seems more like a 19mm. Any one else test this against a different zoom?
