70-200/210 which to buy?
If you want AF then the F series 70-210 is noisy but has excellent IQ - it's not always easy to find at a good price nowadays and you have to watch out for lens separation between the front elements. The DA 50-200 is pretty good (IMO not as good as the F 70-210) and can be had for quite low price...

70-200/210 which to buy?
thanks for all the replies, the concensus seems to be that the older lens iq is better than 50-200. manual focus might not be too bad as CIF can be used if neccessary i suppose and at the price point is probably worth a go.

depth of field question
Yes and no. A 50mm lens is a 50mm lens regardless of what you put behind it, so the DOF doesn't change. However, on APS-C you are getting the same depth of field with a moderate telephoto lens as you would with a standard lens on FF. The APS-C camera therefore delivers more DOF. Looked at in r...

DA 20-40mm Ltd - anyone had a go yet?
what we've seen in the reviews, this lens is big, expensive, slow (focus and aperture), prone to flare and far from usable sharpness (not the most important, sure, but the threshold of usefulness is). if pentax forum says so, it means that is really really bad... any 17-50 2.8 kind of zoom is imho b...

what we've seen in the reviews, this lens is big, expensive, slow (focus and aperture), prone to flare and far from usable sharpness (not the most important, sure, but the threshold of usefulness is). That's not a fair representation of what the reviews say at all. The lens is certainly not 'big'. I...

DA 20-40mm Ltd - anyone had a go yet?
I tend to shoot mainly around the 30mm, or slightly wider end, the 70mm hardly ever gets used, I think I've used it on a few occasions but none that I absolutely needed it, and given the nature of the trip, the 20-40mm suits me well. I'm very used to using just the 31mm, so not having the extra 2mm ...

DA 20-40mm Ltd - anyone had a go yet?
No doubt, the 31mm is a keeper, I toyed with the idea of swapping it for a 35mm F2 + a 15mm a while back but decided that I love the 31mm too much to let it go. The 31mm will still be the go-to lens when I'm kicking about, or for trips that don't require absolute down-sizing, and the 20-40mm will...

HD Pentax-DA 20-40mm f2.8-4ED Limited DC WR hands-on preview. In response to Chaude’s original post here are my initial thoughts on the new Pentax 20-40 after a short period of ownership: Cost: £764 was SRS Microsystems’ special offer price that I jumped at. There have been many adverse on-lin...

DA 20-40mm Ltd - anyone had a go yet?
Hi Adrian, I've bought a copy of this lens prompted into action by the discount offered by SRS. My interest in the lens was due to reasons similar to yours. I'm not competent enough to comment on it's resolution and all I will say on that subject is I'm pleased with the results it produces (so far)....

DA 20-40mm Ltd - anyone had a go yet?
Thanks for the link Conqueror. The review makes interesting reading. MattyH I think it's fair to say the 20-40 could replace your 21mm Ltd but I'd think twice about parting with the 40mm Ltd. I'm keeping my 35mm f2.4 because, although it's a horrible piece of plastic, it has pretty impressive opt...

DA 20-40mm Ltd - anyone had a go yet?
I am going to be controversial here, IQ is subjective. Why? Well is comes down to what you are trying to say in the image. It all comes down to one thing that a professional photographer told me. "As long as the subject is in focus and the composition tells a story, then that is all that matters" Of...

DA 20-40mm Ltd - anyone had a go yet?
Told you I would be controversial. Not controversial in my eyes - I agree with your every word but I do also accept that there are times when sharpness and detail resolution are very desirable, in the same way that having weather and dust resistance is sometimes very desirable. I'm in accord that ...

DA 20-40mm Ltd - anyone had a go yet?
Sharpness IS very important to me. However, there are provisos: Sharpness at the edge of the frame shooting at below f4 doesn't matter. 99% of the time, my subject will be somewhere in the middle and relatively close to the camera, and the edges/background will be more distant and therefore out o...

DA 20-40mm Ltd - anyone had a go yet?
I have little knowledge of optics and lens structure, but I would have thought that to design and construct a precision motor-driven focus zoom lens is technically more demanding and complex than it is for a screw-driven focus prime lens. I would be interested to know if that is correct and, if it i...

DA 20-40mm Ltd - anyone had a go yet?
I've received the lens, and took it for a few snaps in the Lake district a few days ago. Have posted the photos I'm no good at actually analysing things, but the feeling is, it does seem to give me what I miss when I'm carrying the 31mm, though a lot of the time I do find myself going back t...

DA 20-40mm Ltd - anyone had a go yet?
This lens has taken a fair amount of flak on this forum and elsewhere, much of it from those who have not even handled it let alone own it. Also plenty of grumbles about price as though purchase is obligatory rather than a personal choice :roll:. Nevertheless, nearly three-and-a-half thousand views ...

Anyone else looknig forward to seeing what the 10mm Samyang brings?
The brand is developing a good reputation - its latest 14mm & 85mm offerings have been well rated. Apart from excellent resolution the build is quality with big solid focus rings and the advantage of an 'A' setting for AE control on Pentax. 10mm? For me that may be a bit wide for comfort - I wou...
