Help with Takumar Lens Focus confirmation
Try enabling Catch In Focus, put the camera to AF.S and turn the focus ring slowly towards focus while holding the shutter button down, when focus is achieved it will automatically fire. Only Pentax do this and it's a boon.

Interesting, I didn't realise that. Note to self ... Don't bother looking for a M42 500mm f4.5 :(

Help with Takumar Lens Focus confirmation
For catch-in-focus, you might have to short the pins on the camera body. If I recall correctly (I've tried it once), just place some tin foil over the contacts when you screw the lens into the camera does the trick. With regards to focus confirmation: If you try to focus while you're aperture is...

Review - Pentax HD DA 20-40mm F2.8-4 ED Limited DC WR
I'm not sure about 'The use of aperture to control DOF seems to be a dying art in photography these days'. There seems to be an almost obsessive focus on shallow DOF, it's one of the main reasons many people want to go FF, and it's the main reason that Sigma have offered this fast 18-35mm lens - to ...

Review - Pentax HD DA 20-40mm F2.8-4 ED Limited DC WR
...I'm increasingly seeing a trend towards an ever increasing quest for uber sharpness/resolution right across the frame and everything in focus from 1cm away to infinity. No wonder an ever increasing percentage of images published are leaving me cold these days. The reason stuff in real life ...

Review - Pentax HD DA 20-40mm F2.8-4 ED Limited DC WR
You're right Philip. Just like an image that has everything in focus, the real world also has everything in focus. It's just the equivalent of a very, very large print or screen and we can only focus on one bi8t of it at a time. It's the same when we stand close to one of those enormous paintings...

HD coating does make a difference...
Here is not a serious comparison. Just snapped two shots by FA77/1.8 and another two by HD-DA 70/2.4 to show how they perform in extreme light condition using the same settings. As far as I can see, HD did make a difference in good way. As you can see, 77mm gave much harsher purple fringing aro...

HD coating does make a difference...
That test is entirely meaningless. The two lenses have different characteristics, and different optical formulas. You can't expect the results to be identical. To show the difference caused by the coating, if any, you'd need two identical lenses, one with the HD coating, and one with the regula...

Advice on Extender
If you get the SMC Pentax-F 1.7 it will make any manual lens Auto Focus. You may need to get it close by hand but then the AF will keep it focused.

Which lens is your favourite all round performer
The 18-135mm is an obvious choice, weather resistant, sharp, fast focusing and able to focus quite closely. It's a useful range and it's roughly equivalent to the 28-200mm zooms that were once called "super zooms" on film.

Which lens is your favourite all round performer
for now the DA* 16-50. this lens has been my workhorse for a few years not. Its not long, but its wide and bright. Cant wait to pair it up with a k5ii so I can rely on its focus in dim light a bit more :D my only complaint would be flare resistance.

Which lens is your favourite all round performer
After testing my 18-135 against my only Ltd (35mm macro) I succumbed to lens envy and decided a 16-50* and a 50-135* was the way to go. SRS let me spend a morning playing around with both in their showroom. I managed to get shots at several identical apertures and focal lengths of a test target s...

Which lens is your favourite all round performer
I purchased a K30 in the summer and when I tested it in the store it was equipped with the 18-135 WR. I liked it so much that I went back and picked one up. It now is my everyday lens and rarely comes off the camera. The photo of the model train was taken at 135mm f8 1/125 iso 3200. Mike

I'd back Vic on the 18-250 / 270. I have found that you will get the best out of it at f8, but then that's what people are saying about the 18-135 as well.

Which Pentax 50mm is best?
So there you have it, we are still waiting for a good 50. Really Pentax should take the glass of the 50 f/1.2, put it into a new Limited WR body with DC and stop it down to f/1.4 and then we could all complain about the price :P ! What's the point in using the 1.2 design and stopping it down to 1...
