Any of you guys with the FE28 and the 21 adapter? I read Jordan's review and it seems mostly positive. Thinking of picking that up instead of the 16-35. Reason being I don't shoot a lot of wide angle, so not sure how much I would use the 16-35. The adapter has a few things going for it, it's cheaper, lighter, would give me a 2.8 instead of a 4 and because I have the rII, don't necessarily need the OSS. Bad things are that no filters, but I don't shoot with them a lot. Obviously it's not going to be as nice as say the 25 Batis and probably not as good as the 16-35 @ 21 and f/4, but for the $250, might be worth picking up. If it performs at half the performance of the 16-35 I could live with it at 20% of the cost. Like the fact that unlike the Fuji converters don't have to menu dive to toggle it on. Really love the 28 as a prime on both the rII and my a6000 so it's going to stay.
