@ Dr. Croubie

Glad to see that I finally found a person who has this lens. I've been on other forums, and it seems like no one ever heard of this lens. Thanks for the really helpful information. Anyways, I have read reviews that praised the IQ on this lens especially at f/2 which is what I'm looking for. I don't mind having to use live view to focus, so that's a good thing. For me the more important factor is the IQ, I don't mind not having AF like I said on my previous post. Also, when your Kateyez split-screen prism comes in, do you mind telling me if ordering one helps for MF? I've been looking to order a new focusing screen because mine unfortunately got badly scratched. I bought a 180 split focusing screen (can't remember the brand though) from my local camera store. The owner said that it would help improve MF, but when I installed it the screen was extremely dark when zoomed with my 18-55mm. On my 55-250mm it was worst, I could not see at all.
