FA* 24/2 AL [IF]
Recently I've been using the K24/2.8 quite a bit, and have found the focal length to be very useful. While I'm not ready to buy the FA* 24/2.0 right now, it may be worthwhile to consider adding to my personal road map, so I've some questions: Is the lens only available in silver, or can it be had in black as well? More important, how is it optically? I seem to recall some people saying that it wasn't very good - although I don't recall any specifics. Boz's site mentions an AF/MF clutch. What is that? Does that mean the lens can be used in auto focus mode and then adjusted manually without having to take the camera out of AF mode, like some of the new DA lenses? Thanks in advance for any and all comments. Shel -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

Yes, except you have to snap the focus ring backwards to do it, if I recall correctly. -Aaron -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
Re: FA* 24/2 AL [IF]
Boz's site only shows a silver version so I'd go with that. I've heard it's a very fine lens. Well beyond my price range right now.

Re: FA* 24/2 AL [IF]
Far as I'm aware, the FA*24/2.0 is/was only available in silver. It does not have QuickShift, it has a clutch on the focusing ring. Slip the ring on the lens and the AF coupling is disengaged regardless of what the setting on the body is. This nets the ability to focus manually while the camera is in AF mode, but is not as handy as just being able to turn the focusing ring for a fine focus adjustment. The camera will also disable the shutter release if the focus point is not sensed to be locked in properly with the green indicator. My reservations about the 24/2 stem from the wide disparity of comments I've heard about its optical performance. It seems most people who have used it with film love it, but most people who've used it with the DSLR bodies find too much chromatic aberration and poor sharpness wide open. I think Rob Studdert posted some comparisons showing the A24/2.8 and FA*24/2 performance, using the *ist D body, and the A24/2.8 was a substantially better performer. 24mm is an excellent focal length on the 16x24 format, however, and it's well worth getting a lens to cover it. I had the A24/2.8 and did a lot of work with it. I only sold it after I'd been using the FA20-35/4 a lot and realized that the latter was easier to focus with manually due to better wide open contrast. The A24 is likely a little better performer at the limits than the zoom, but the option of AF, the better manual focus contrast, and the flexibility of having 24-28mm focal length available on the camera appealed to me more.

Some people love it, some hate it. I had one and sold it on in favor of the FA 20 F2.8. I didn't like it's wide-open performance, and I had bought it for use in low light. That said, I have seen stunning images made with it on a DSLR, stopped down. But it is out of production. Reports are that the CA problem can be corrected in software. I can't attest to this. If you don't need speed, the DA 21 F3.2 is an alternative. Or, as Godfrey mentioned, the FA 20-35 F4 is very nice.

The FA35/2 and FA50/1.4 are my low-light lenses at present. Would be nice to have a 24-28 f/2 lens, but I'm too leery of the FA*24 to be interested. > Reports are that the CA problem can be corrected in software. I can't > attest to this. Most Red-Green and Yellow-Blue CA can be corrected with Camera Raw pretty easily. The necessity of having to do it is a bit of a pain, and correction is never perfect. > If you don't need speed, the DA 21 F3.2 is an alternative. Or, as > Godfrey mentioned, the FA 20-35 F4 is very nice. The DA21 is one of the few lenses now living on my "wanted" list, for its small size and excellent performance. I'll probably buy it with the 10Mpixel body when that comes available. Please, Pentax: a DA28/2 lens that is compact and high quality. I promise I'll buy one. :-) Godfrey -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
Re: FA* 24/2 AL [IF]
It is an excellent lens, both with film and digital. Only made in silver, but the lens body is metal, not plastic. Someone has just explained how the AF/MF clutch works, so I will not comment on it again. In some high contrast situations, such as the typical dark branches against a bright sky, it may or may not show CA, more noticeable when shooting digital. It can be corrected in post processing, though. I thought of selling it but in the end I decided to keep it because it is quite useful both on the film bodies and the DS.

Re: FA* 24/2 AL [IF]
Shel, Godfrey is right. Rob was the one to note chromatic aberration as a digital problem. I've used the lens and absolutely love it on film and have found no problems on digital. (maybe I'm not critical enough?) It is really terrific to have a fast, wide prime on the DS. It will remind you of the 35mm f2. And it balances OK for a big lens. Regards, Bob S.

Mine is silver - or more like grey, really. Not good? It's absolutely excellent! The clotch: You can push the focusrig back and forth to switch between AF and MF. About adjusting: Not really. In AF mood the ring doesn't work. You must choose AF or MF. But you can choose by using the ring only. Pulling it back means the camera is in MF mode - that's why they call it a clutch.

Re: FA* 24/2 AL [IF]
It is one of my favourite lenses, the other being 77 Limited. I use it only on film bodies, so don't know how it works on a DSLR. I love it for for it's many qualities, being able to produce very pleasing images overall, very good flare resistance and for its speed. I can see it as a great combo on K10OD or fure K10D for example. Fast 35mm equivalent together with SR should be able to do a lot. I'd love to see DA equivalent 16/2 for 1,5x crop on DSLR. This certainly would cut my cake. There certainly is a disparity about its sharpness. Yoshihiko's tests at http://www.takinami.com/yoshihiko/photo/lens_test/pentax_superwide.htm l shows it as the best of the 24 Pentax lenses, also photodo 's results vwere very good: http://www.photodo.com/product_93_p4.html OTOH, as Godfrey says, many don't get such results. My take is - highly speculative - that maybe it is due to it's plastic-moulded aspheric element (which is the cheapest, however not the best way to produce an quality aspheric element) which might result in worse performance if it is not perfect. Or it is simply the matter of users different personal expectations.

FA24/2 is the only Pentax lens option if you need "fast" however from my experience the FA is only really exceptional when stopped to middle apertures and above. My semi-formal testing showed that it exhibited far more prevalent CA than my A24/2.8 and that it only matched the sharpness of my A24/2.8 wide open when stopped down to about f4 and then the edges were still softer. I've had the benefit of owning two of the FA lenses concurrently so I don't expect that I'm dealing with lens QC issues as both FA lenses behaved similarly. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
