SDM focus does nto work with tele converter
Just been reading the topic on extension tubes and wonder if something similar would explain the issue I am having. I picked up a tele converter... it has all the contacts including the two inside the lens for autozoom/SDM. With a continuity tester I verified that the contacts are functional from...

SDM focus does nto work with tele converter
AFAIK the 2 contacts inside the body provide only power, either for the SDM electronics or power zoom on suitably equipped lenses.

SDM focus does nto work with tele converter
My 1.4x (think it's Tamron) converter works just fine with SDM, so not sure what's going on there?

SDM focus does nto work with tele converter
The tele-converter is a Tamron 2x pz-af mc7. I'll have to look at the other contacts. If the two internal contact are only for power, then Perhaps something is missing. But all seven contacts are there,the A* lens has six. Hmm, one of them seems to be indented further than the rest. I'll h...

New to me lens from e-bay, Help
Try for some information on the Lens, Site is blocke from the office so i can't see what is says. Generally the Macro is at the long end, i.e. 105, of the zoom and allows for a close focus for close up work. On one of my similur lenses this allows for the focus ring to turn more, others have a...

Airshow Lens
I picked up one of these lenses with the 2x Sigma teleconverter yesterday from SRS, and I have to say that there appears to be some truth to the rumour that the 2x converter and the 70-200mm HSM II don't get on! Basically, it won't AF with the 2x converter, but more worrying than that is the fact...

Is it possible the 2x converter could be faulty. It certainly sounds like there is a fault somewhere with either the lens or the converter. Have you given the mounts and contacts a good clean:?: I would go back to Chris and try another converter if i were you.

Can I ask what made you go for the Sigma 70-200mm f2.8 over the same offering from Tamron? Well, annoyingly, the fact that it came with the converter and had the HSM really! I've read the reviews between the two lenses, and as usual both had strong and weak points compared to each other, but I di...

Sigma 70-200 HSM II & Kenko 1.5x Converter Pics
I purchased the Sigma 70-200 HSM II last week, and apart from the bundled Sigma 2x converter not working with it, I'm pleased with it. I wanted the teleconverter for the odd time that I needed something a bit longer, and fortunately the Kenko 1.5x DG converter that I already had works fine with i...

Old vs New
OK I am being tempted to get a pancake lens for my K10D - possibly a 40mm or the 21 mm as I want a light and small lens for general use. At the moment the 40mm Ltd is looking good but I already have a 28mm f2.8 Pentax A lens so all it lacks is the autofocus and that's not really a deal breaker as...

He's my thoughts for what they are worth, the 28mm can almost be preset or fixed focus and left alone in normal light conditions, where everything will be "apparently" sharp. It don't get quicker or better than that for a walk around lens:!: Also no cost implication, it allows LBA to used elsewhere ...

The pancake would be new and AF - I can quite see why you'd get your mitts all over it with manual focus. But will the Ltd be a sharper lens. I guess I should just use the 28 for a while - good enough is good enough :) Mike

Gig photography
I'm not saying I was any good and these are some of the first gigs I ever took pictures at but this is one of the gigs that my Fujica ST705 got white at. All I had then was a 55mm F1.8 Fujinon lens ( very good ) and a Tamron AD2 28mm F2.5. The Takumar 85mm F1.9 came later, it was my first bit of Pen...

Artistic Nathan nudge nudge know what I mean. Seriously though it does look pretty realistic, I'd have thought it was film if you hadn't said. It's funny though, I used to try and spend all my time trying to minimize grain and here you are actually adding it. The world is a funny place. What I wa...

road map
Web page at the moment can not be found, so it's telling me. I guess they realised they'd put it up too early and have removed it. Shame. Hopefully it will be back up on Monday.

hello all... new to (D)SLR, i went for Pentax=) yey!
You're welcome. I should have added that the bokeh rendered by the lens I suggested is about the best you'll find for the money. The out of focus (OOF) background is achieved due to the much shallower depth of field produced by the FA 50mm 1.4 If you are in UK, try www.srsmicrosystems.co.uk . Men...

16-50
Aye im guessing this is good because it will have been sent back to have the problems fixed Ive heard the 12-24 is a very nice compliment to the 16-50 because of the overlapping focal lengths [edit] Im waiting for a weathersealed wide lens.. they should seal the 12-24 and announce it at PMA...
