Thanks for all the 35mm comparisons Carlo. I'm not surprised by your decision to keep hold of the sigmas, a cracking combo that can do it all. The bigma consistently produces slightly softer backgrounds than the GM in every comparison I've seen. The size wins for me though - I reckon I'll have the GM for a long time!
I'm pretty much done being lens tester unless someone wants to see something specific. 35mm is a key focal length for me so I needed to test this for myself. There is so much hyperbole and ownership bias on forums and reviewers don't really look at things like rendering critically enough. I think outside of side by side tests, for practical real shooting purposes, there isn't a whole lot that really separates the Bigma/GM/35i. What may sway me towards the GM at the last minute is AF performance, but the Bigma AF is good after firmware updates and I have no issues with the 35i AF.
If I didn't already have the Bigma and were starting from scratch with a fast 35 today, I'd probably grab the GM on the basis of size. But since I already own the Bigma, basically the net cost of buying the GM after selling the Bigma is the cost of the 35i. And then lose out a bit on the rendering of the Bigma, and the size of the 35i.
