Latest Review Posted SMC Pentax-A* 300mm F2.8 ED [IF]
I've had the pleasure of using a very wide selection of Pentax lenses made from the 70's to present (2019). Optically, this model ranks among the very best. Pros: - Outstanding contrast and color rendition. - Astrophotos are one the harshest tests of a lens: Sharp, almost color-error free astrophotos at f2.8, excellent sharp from f3.5, Equal to many purpose made astronomical instruments by f4.5.

It's a pleasure to manual focus. - Focus Preset ring is quite useful. Cons: - A significant negative to this otherwise stellar model is the extreme nose-heavy balance on the mount point - so don't even try o...
