Pentax-Asahi 200mm F/1.4

[airconvent]

Came across this item for sale. (its already sold).
But curious that such a long focal length actually has a maximum aperture of f/1.4!
At telephoto objects would be dim but now with a fast lens, would they cancel each other out? Anyone has experience with such fast and long lenses?

It said 1:4 on the lens Too much LBA

it's not f/1.4, it's 1:4 , which mean f/4.0.

200mm f/1.4 will have a huge front element

By the way, user111, it is my understanding that Pentax co-developed the coating technology with Zeiss during the late 1960s to early 1970s. It's called SMC (Super Multi Coated) in Pentax, T* in Zeiss (the "T" stands for "Tranzparenz belag", or "Transparent lining")...

This is why Pentax lenses are well-sought after for their SMC fame.

Talking about coatings, had a short power-out in my place a few days ago. So decided to take a candlelit shot with my K100D and 16-45. Here is a shot with a Hoya HMC UV filter (notice ugly green flare, ugh!!!)


Here is the shot without filter


Best results = no filter

Yeap, agree that the pentex lenses resistance to flare is amazing.
