I'm thinking of getting a 270/300mm lense for 4x5. I was ready to settle on the G Claron but then did some checking on the Schneider web page. They say that t he G Clarons are optimized for 1:1 reproduction (macro - close up work) but can be use for infinity focus if stopped down to F22+.
Does this mean the lense really doens't perform well at infinity focus as far as actually focusing sharply on a distant object and relys mainly on small aperatu re (F22+) depth of field to achieve sharpness? Intending to do only infinty foc us work (no macro/table top) and being a stickler for sharpness, would I be bett er off getting a "regular" 270/300 lens, like the Nikon M or one of the Rodnesto ck/Scheider F5.6 lenses?
THX in advance,
