Purple Fringing with DA* 200mm

I've just bought one of these (brand-new) and am a bit surprised at how bad the PF is - from F2.8 right up to about 5.6

Is this normal for this lens? or do I have a defective copy?

Can't comment on the DA* 200mm but the FA* 200mm was pretty bad in this respect. So if Pentax recycled the design (which is likely as the optical specs are the same), then you're just going to have to live with it

I think the DA* 60-250mm has much less fringing. I also briefly used the A* 200mm and didn't find it to be as problematic, but the manual focus ended up being really annoying on digital.

Yes the 60-250 gets better reviews - pity it weighs (& costs) half as much again as the DA* 200 :-(

I picked this lens to be able to do hand-held - wandering about in the bush for opportunistic wildlife shots. I don't think that would work too well with the 60-250

It seems like it handles PF pretty bad from what I've read, totally different from for example the DA*300/4. Pentax SMC DA* 200mm f/2.8 ED [IF] SDM - Review / Test Report - Analysis
Also I can not understand why the AF is so slow with the lens when the DA*300 is pretty fast.

The zoom is only 300g heavier, but it gets much bigger when zoomed in, so I guess overall it wouldn't be as convenient handling-wise.

You should be able to import one for around $1200 if you decide that the prime isn't right for you, though.

Yes I have a DA*200 and have the same issue; nevertheless I like the lens very much, I simply never use it wide open...

Yes, this was the reason I sold mine after less than 2 weeks. I wanted it specifically for sports photography, and it just wouldn't cut it. Otherwise it was nice.

It still took pretty nice images, though not quite up to the standard of the F*300 (or even the K200/2.5). But if the AF speed is fast enough for you, it's a nice size with good overall IQ.


Many people love the DA*60-250, but it's never impressed me that much - both the images I've seen and when I tried it. However, PF usually doesn't bother me that much, whereas other image characteristics make a big difference to me. Nevertheless, PF two full stops in seems a bit excessive. IIRC I was doing fairly well by f/4, although I see photozone still got some: http://images.photozone.de/8Reviews/lenses/pentax_200_28/samples/IMGP0901.jpg

Purple fringing is pretty bad with the DA 200. The nice thing is that it is really easy to fix in Lightroom 4 and not a big deal (FA 77 and D FA 100 both fringe worse, in my experience).

My has PF too, but better than the K200/2.5.
It is slow, and I ended in most of the time using it in manual focus.
Also I rarely use wide open in day light. It has weaknesses but also strengths.

My copy has pretty fast AF, I use it for sports and birds in flight too. But PF is an issue, the optical design is exactly the same as the FA200, designed for film.

Purple fringing wide open on a K7; at F4 issue is largely reduced; K5IIs seems less prone to PF, though

At F4

Nowadays it's a fairly simple fix in PP with either LR4 or CS6 and I'm guessing various other PP software as well.
