Lens Upgrade Dilemma

[o2mpx]

Have been using the 21mm, 35-75mm, and the 120mm for landscapes. Would you replace them with the new 28mm and 90mm (already have the 45p), if image quality, specifically resolution and detail were the primary objective? All shots taken within f8-11 range.

No, I think you already have exceptional image quality from those lenses. The new lenses would be more compact and light weight but if anything there would be a very slight drop in image quality.
