Upload & Sell: On
I picked up a ZM Biogon 25/2.8 in a trade. It's my second go-round with the lens. I knew it was great on the 5n, but I didn't think it would be as good on the 7 and I had the Elmarit 24 ASPH by then, so I sold it. So this time around, while I was curious to see what it was like on the 7, I figured I'd end up using it a few times on the GXR and then selling it, but I was wrong. It pairs up really well with the 7. The corners aren't perfect focused for infinity, but they're better than the Elmarit and there's no color shift that I can discern in the short time I had to play with the lens before other duties called. What I love best about the Biogon is the close up performance. I like the bokeh, which is something I find tolerable at best with wides, and the low distortion is fantastic.
First is wide open, second is at f/4.
