NEW TAMRON 2X CONVERTER PENTAX AF FIT
I have just received my new lens, and could not wait to use it. But have had a few problems. I hope someone could explain what I may be going wrong. I fitted it on the camera and then my pentax 50-200 zoom lens on manual it works fine. Switch to Auto and then the problems start, focuses fine at...

NEW TAMRON 2X CONVERTER PENTAX AF FIT
Yes Mongoose is right, at F11 you'll need an extremely bright and contrasty subject for the AF system to get its teeth into. Also, as you approach the extremes of the focal range of zoom lenses the image quality tends to drop off a bit and adding a converter makes it even worse. Even with good qual...

NEW TAMRON 2X CONVERTER PENTAX AF FIT
I was taking moonshots through a telescope at 2000mm F10 the other night and was surprised when the focus assist started working. Still it is a pretty good telescope and it was a very clear night. That's the highest F stop I've seen K10D's AF system consent to work.

Pentax 10-17 or Sigma 10-20
Not many suppliers seem to list whether they actually have stock. You have to ring around or take a risk. I recently got a Sigma 10-20 from Warehouse express. I had to wait a week but I thought that at the £289.99 price they were quoting it was worth the wait. Looking around at the places I ha...

Pentax 10-17 or Sigma 10-20
Hey Niblue, nice to have you back again, it's been a while! Hope there was nothing wrong, and if there was that it's sorted now. :) Looking forward to more Firth of Forth pics... Dan

Pentax 10-17 or Sigma 10-20
Dan, Thanks for the welcome. I usually only post on these sites when I'm actually in the process of buying new kit so dissapeared last time once my lens buying urges were sorted out. They're back now though as SWMBO is off to Singapore in July so I'm deciding what lens to ask for as a pressie....

Late arrival DA* lenses causing a problem
Rumor has it that the lenses should be out by the end of May. Of course rumor had it that they would be out April, and before that March. But I also heard rumors that the lenses may not actually make it here until September!! OK, I'm not one to base my purchase totally on products that do not yet...

Late arrival DA* lenses causing a problem
I can supply an Ex-Demo (as new) 18-55 DA for £40 to anyone who is interested in something wide for the short term. You would probably get the majority of this back if you flogged it on Ebay when the other lens arrives.... Chirs

clearout
I'm selling off some of my surplus-to-requirements camera kit on Ebay, where I am known as Thatguypinchedmyname. Up for grabs are the following - Not the worlds best lens, but works well as a walk around on film - The only example of this lens I've ever seen, even a google search for ...

Russian 500mm mirror lens
agian, with your dslr, you will probably be forced to use a teleconverter to get that lens on the body. Well, it's moot now, since I've purchased the 600mm Sigma that Chris@SRS mentioned a few posts back. It's a stop slower at F8, but 100mm longer. Watch this space for more full moon shots when ...

Soft-Focus 2.2 85mm
I have this lens. M 85 soft 2.2 I love it to death. Won't sell (mines well used...it shows..) here's the low down.... with my ds2, I use the 85 (85x1.5=128mm) with a 1.7af teleconverter to make approx 218 mm portrait lens. the image softness is controlled by aperture...ie f2.2 is very soft, ...

Soft-Focus 2.2 85mm
This is going to be totally unhelpful probably, but I had one of these and found it totally useless. It may well be that it just depends on your style of photography... So you have one vote for and one against now. You'll need to try it for yourself I'm afraid.

Soft-Focus 2.2 85mm
Good point JR. I like soft focus. Don't mind grainy...in fact, my favorite images would get shredded at a Professional Photographers of Canada competition. I can create images that they'd like, but I wouldn't much care for them. Nick Vedros lectured at the conference I attend recently. I li...

Soft-Focus 2.2 85mm
If you're doing portaiture, or even nudes, for paying customers, do they want "sharp" or "atmospherical" pictures? I mean, soft is different from unsharp. For soft portraits I can either use a 1.4/85 or a not so modern 2.8/85 and use it wide open, but then there is point shar...

old lens on new camera
A. The answer to your question will depend on what "old lens" you are using, so please provide that information. B. Alternatively, read pages 186 to 188 of the manual. But if you are not proficient in Japlish, go back to A. G

SMC 28-105mm
If the lens looks like it is in good condition then I think it is probably a bargain regardless on whether you can get anything back on the camera. Check that it comes with its hood, PH-RBC 58mm, which has the removable panel for using a polariser. The 28-105 is still available new, in black or s...

Your Help/Advise [ Lens ]
Hi and welcome, here are my thoughts: 1) doesn't really do a lot that your kit lens doesn't. It's a bit longer but half its range is already covered by your 18-55. If you get a long zoom, it will be totally covered. 2) All the macro lenses in this price range are excelent. Both the Tamron and ...
