No, it does not. The lens seems to work fine in all respects, fast and silent AF, very nice color rendition, just great. That is why I concluded it was something else...

Thanks John and Glyn, need to do some tests. I will try to clean the contacts, although this has happened since new. As to the SW, that makes sense, but I have updated Aperture today to the last update and still does not recognize the lens.

But I do remember someone else raising the same issue with this lens....

95% here, I think I got embarrassment wrong (one s)

My Pentax 18-135 is not recognized by my camera and shows up in EXIF data as "unknown lens", and that happens also with the latest firmware update. I had read that others had the same problem, is that the case? I would assume that if it is not recognized, then also in-camera lens correction would not work, do you know if that is the case?

Is this lens actually made by Pentax? The fact that is not recognized + the unusual (for Pentax) filter size made me think about this. Any thoughts?

Great shots, my preferred ones are 1 and 2. I always like b&w, but I also love the atmosphere in 1.

IMO this is the point, depending on your photographic priorities the conclusion might be different.

Personally, I think the FA 31 Limited is really special and I would always recommend it. If interested, there is one for sale for 740 euros.

When you go to check out, you will find it under the lens description (view protection plans) and it seems to be 84 usd for 3 years for this lens (plus tax?). I do not know how you add it to your basket. It is offered by Sagemax and you will find a detail description and comparison to the manufacturer's warranty...

I have not tested this myself, but I understand that B&H have a strong reputation....

Have you considered ordering from B&H? It's 685 GBP shipped to UK including duties and taxes, you can add to that int'l warranty. They have it in stock

Thanks for posting this. I think this is a welcome change, the user experience is not really what it should be and hopefully in the future they will move away from Flash, as it means the site does not work on iPhones and iPads, limiting its usefulness.

Another vote for number 3!
