Who lah? Are you also thinking of jumping?
Like they say, the grass always looks greener on the other side. Likewise, Canon shooters also think of jumping ship to Nikon.
As for me, I'm more interested in details. You can have the cleanest JPG/RAW but what's the use when there's no detail to work on? Nowadays PP also can get very good results with 3rd party softwares. For me, I rather have slightly "noisier" file with more details and work on it from there.
Oh, just realised that I forgot to mention the D800 samples I posted were reduced to 5DMkIII resolution to compare apples to apples. Somehow, photobucket does not do a good job of showing the details.
I thought I saw somebody shooting at the BMW girls with a 35mm today...
Good advise. If in doubt, buy both !

I did not go IMPACT on Saturday. Was around shopping and sight seeing LOL. Will be going in for round 2 today =D when you go up close with 35mm the image feels differently compared to 85 taken from further away although similar magnification. I like 35mm but need go really close...
