Pre-order Sony G lenses: FE 24mm f/2.8, 40mm f/2.5, 50mm f/2.5
I don't know, I think I'm with Steve here. I will probably buy the Sony 40G anyway, but I'm disappointed looking at all the sample images. The bokeh and rather harsh rendering reminds me of the FE 35/1.8 (which I currently own) than the Sigma 45 2.8 (which I used to own). The Sigma 45 had fantastic rendering, very smooth, no nervousness, which the FE 35 and the samples I've seen so far from the 40G readily exhibit. Every bokeh-centric image at the DPReview sample gallery for the 40G looks harsh. Look at similar shots in the 35GM gallery in contrast - not perfect, but almost.
The FE 35/1.8 is a great utility lens, with little focus breathing, superlative AF esp. in video and AF-C, great sharpness near MFD, very punchy/contrasty images and even nice bokeh with certain backgrounds. I expect the 40G will be similar. But I much prefer the images I got from the Sigma 45 within it's operating boundaries. Problem is, that's a utility focal length for (35-50) for shooting my kids so I needed a utility, general purpose lens, not a specialist IQ lens. Guess it depends on how you define IQ - I suppose the 40G will be better in terms of something like the product of real world performance x maximum achievable image quality.
