SDM Lenses
The K10D can be flashed back one version which was the firmware that enabled SDM on the body. This will allow it to use the DA* lenses that have screw drive ability to focus using this method only. Yes that's the one exception, I simply wished they had a menu option though :|

RIP SMC-M 200mm
I dropped a SMC-A 28-80 and did the front element a while back.:( Still it taught me to be careful and change lenses over something soft, like my camera bag.:wink: Just a thought, is it worth having repaired by Harrow Technical?

RIP SMC-M 200mm
Equally good, and more practical, is the F 70-210. I'm waiting to receive an A 70-210, and will report back when I get it. G

RIP SMC-M 200mm
A good replacement for the M200 might be the A70-210 f/4 zoom. They are very common on ebay and so normally don't cost much. I have an A70-210 f/4 around here (somewhere) that I was thinking of selling. As far as I'm aware it's optically fine, but the zoom is very free so it will slide if you point...

macro lens 5omm prime or 35-70 zoom
In my experience, yes. For macro work using tubes and bellows I find the slower (f/2.8 - f/4) Tessar-type lenses work the best as they have fewer elements and a very flat plane of focus (in other words the corners, edges and centre all reach their optimum "sharpness" at around the same time, wher...

Next lens advice..
For a "budget" high quality lens think about the DA 16-45, it's a great lens and although I recently upgraded to the DA 17-70, it's only "slightly" better. For wide FOV landscape shots I prefer to use a longer lens and use a stitching program to make a panoramic as the front to back perspective ...

Next lens advice..
Is there such a thing as a landscape lens (leaving aside f64 lenses on view-cameras)? I don't think landscape photography places any particular demands on a lens, unlike macro (V Sharp, flat field, close focus), portrait (50mm - 120mm, good skin rendition, wide aperture), sport (long, fast, and f...

SMC 1.8/55. Anybody use it?
Wonderful shots Beachboy2. I'm looking forward to getting the chance to try it out although my eyesight is probably not the best for manual focus! Dave

SMC 1.8/55. Anybody use it?
Yours has the K-mount, but it's optically the same as the Spotmatic-era lens. Almost all the original K-mount lenses were simply re-mounted Takumars. That's one reason why they are often preferred to the later M series. It wasn't until the original Limiteds came along that Pentax was able to im...

New (Old) lenses
Well having got home and examined the lenses and checked the PF lens database I'm more than thrilled with what was in the parcel, they are all in perfect condition, no fungus, scratches, cleaning marks or sticky diaphragms and the finish is only slightly worn. I now see why you say I got a bargai...

New (Old) lenses
The very narrow focus rubber ring on the 40mm lens is loose, should one just glue it in place? Yes, but don't use a superglue-type CA adhesive in case it ever needs lifting at some point in the future. Something like Copydex (or any PVA glue) will give a strong hold yet will allow the ring to be pee...

28, 35, or 50mm as standard lens?
The FA 35mm f2 is a superb lens which I use a lot. In its Samsung coat it is quite cheap at Currys or PC World or somewhere like that about £250 I think (assuming 250 isn't way too expensive). For street photography how about the 21 ltd? I think it's fairly reasonable from Amazon again about £250...

28, 35, or 50mm as standard lens?
I had a 28mm A and didn't get on with it all. It just didn't seem to deliver the same richness of colour that other lenses do but maybe that was my fault. Anyway I sold it and never looked back! Mike Did you have the white balance on daylight or auto? I found my K-135mm can look dull at first unti...

Tamron 10-24 ePHOTOzine review by Pete Bargh
Stefan, a DA* 11-16 is unlikely to be much better than the 12-24, nor much smaller, and it would lose the useful 8mm at the top end. Why would you want it? G I'm with you there George, that's why I like the idea of the 10-24 Tammy as it could suffice as a walk around street lens, I actually foun...

Tamron 10-24 ePHOTOzine review by Pete Bargh
I doubt if the 11-16 will ever happen in Pentax mount, but there is no doubting that it's a very fine lens. Anyway, the range is too small for me as I found 10-20 a nuisance and reverted back to the 16-45 a lot of the time. Having used a 12-24 and found the coverage to 24mm made all the differenc...

Tamron 10-24 ePHOTOzine review by Pete Bargh
[Why not get a DA 14mm or DA 15mm Ltd then? The 12-24 is a big lens, the Ltd very small. K. Kris I think you missed this one Anyway, the range is too small for me as I found 10-20 a nuisance and reverted back to the 16-45 a lot of the time. That's being said about the 11-16 so 14mm would be ev...

Tamron 10-24 ePHOTOzine review by Pete Bargh
I don't "need" more than the 17-70 in most circumstances, certainly not enough to spend 12-24 money (even the Samsung at £450 'ish), but it would be nice to have something centred around 14mm which I find a very workable F/L for quick wide shots... Why not get a DA 14mm or DA 15mm Ltd then? The 12-...

Tamron 10-24 ePHOTOzine review by Pete Bargh
Well, I finally visited SRS to try out a Tamron 10-24. Luckily Chris had 10 units delivered that morning, so I was able to try several copies. As expected there was a degree of sample variation and having found a particularly well balanced one I proceded to try it against a s/h Samsung 12-24 that Ch...

Tamron 10-24 ePHOTOzine review by Pete Bargh
The image will appear totally natural is you move your eyes very close to the screen. If you can focus about 3 inches away, then give it a try.
