Already got a magnifier. And I'm not a fan of split prism. Besides that I probably will retire the K-20, so spending more money at it seems a bit like waste.
IMO OOF rendering generally isn't important in the studio. Because it isn't much to render in the background. What's most important is how it renders skin, hair and eyes. Harsh OOF rendering of hair could be a problem. I'm not sure. So I think what I'm really asking is how the 28-75 will focus in the studio light. Is that lens critical towards light temperature? I had one in the past, but I can't recall how it behaved in odd light. -- MaritimTim http://maritimtim.blogspot.com/ 2011/3/20 Boris Liberman <[email protected]>: > On 3/20/2011 2:39 PM, Tim Øsleby wrote: >> >> The combo seems to front focus a lot in the studio.
