I think that "hybrid aspherical optical elements" dosn't mean automatically worst quality of the lens or of the image or both. It highly depends on design and on the precision of manufacturing.

Pentax fa 31mm limited: I'm not amazed...

Maybe I was misunderstood. Neither complain of nor will ever abandon my 31Ltd. Its field properties are excellent as well the sharpness. Together with the overall color rendition of Pentax it satisfies my photography taste.

This lens is considered of one of the best ever made. And is spite of all it is not flawless. Mine for example exhibits too much purple edges at contre-jour.

The three FA Limited 43, 77 and 31, was originally developed by Jun Hirakawa. However, Jun prefered smaller lenses that should look more elegant. He originally designed a FA31/2.4, based on the optical formula of the old K30/2.8. However, the decision maker at Pentax/AOC didn't like that for some reasons but wanted to have a faster lens. Soon later, Jun was replaced by another two AOC optical designers to take up the project, namely, Mr. Ito, Takayuki (伊藤 孝之) and Mr. Murata, Masayuki (村田 將之). And they finally made the FA31/1.8 Limited lens

Congratulations! If I may speak to the topic try Pentax HD 20-40. Not so broad in the focal range but giving excellent quality. Just my personal opinion. Happy New Year!

The only problem with my K-3 was the reluctant auto focus during my summer trip. Unfortunately I missed a lot of scenes. In spite of all I won't change my Pentax. It is very well build camera. So if an AF improvement is on the way I will consider a new buy.

I had the FA version. Unfortunately I couldn't take a proper picture with it. Maybe my copy was bad.

Sorry! It was a mistyping..


By the way I have found in my files the mentioned patent. And not only.
100/2.8 WR : patent US4770516

50/2.8 Macro : patent US4923292
So I was really wrong! Sorry.

Yes, I can be wrong. But can anybody cite the patent of this lens ( D FA 100/2.8 macro)? Personally I couldn't find it.

As far as I know my SMC Pentax 100/2.8 WR is a Tokina design. May be I am wrong but this lens I am not going to sell at all.
On the othe hand I am so sorry that the D FA 50/2.8 is so plastic and slow. Optically this is fantastic lens.

I have seen much better shots with this lens. Where are the "sharpness" and the "detail"?
