Front/back focus; lens v.s. camera
Actually, that one lens does need adjustment, but it needs two. My DA* 50-135mm lens BF's at 50mm, and FF's at 135mm. Go figure . . . 'cause I can't. I've come across this phenomenon before with a Canon 28-105mm lens - it backfocused very slightly at the wide end, but front focused considerably at 1...

Front/back focus; lens v.s. camera
The 55-300 is running about $400 here. Not a bad price as the lens seems to be getting decent reviews for the most part.

The 55-300 is running about $400 here. Not a bad price as the lens seems to be getting decent reviews for the most part. Just had a look at B&H and they have it for US$359 + $41 postage. But they don't accept pay-pal from Aussies :?: but they will accept mastercard if i send them a pic of my card fr...

Front/back focus; lens v.s. camera
but they will accept mastercard if i send them a pic of my card front and back :? Not sure i would want to do that though. You have to give them all the same details though, don't you? Or is it one of these customisable cards with a particularly unattractive picture of you on it? ;)

but it still concerns me that they will have a pic of my signature on my mastercard in there possession for as long as they want to keep it. A little disconcerting thats all. That's a good point. I imagine they want proof that you physically have the card - see if they'd accept pictures where the...

I expect they'll look at the quality of the photo and decide if you deserve to own this sought after high quality glass.:mrgreen:

slide boxes
I've just joined as I saw a posting from veteran Pentax User, 'Pwynnej' back in January, trying to obtain slide boxes like Fuji used. I have hundreds! I was hoping to get a bit of money for them but he can have some for postage cost - or I could drop in as I come Denbigh way occasionally. Do get in ...

Is my camera broke?
Hi all, I have been having a problem with my auto focus and the little red dot thing. I have the litte red dot set in the middle but it keeps jumping to either side of the view finder plus the camera will not focus on anything.. I have tried different lenses and it does this with them all so I am...

Is my camera broke?
If removing the battery helps, try resetting to the factory defaults. It may be a slim chance that will actually fix the problem, but ff that simple test fixes it, all the better. Certainly can't hurt. Otherwise, like you suspect, you've got bigger troubles and likely need to send it back for rep...

extension tubes
I think they were correctly described, I'm afraid. 'Auto' here refers to automatic diaphragm. There are others around here much more knowledgable than me about things macro but I'm sure auto focus extension tubes dont exist and the reason for the absent contacts is that these tubes are designed for ...

extension tubes
Here are two examples with very similar tubes and a Pentax M 1.7. The lens was at its widest and manual focus, but I can't rememeber the no. of tubes I used. They are hand held in the garden with a breeze blowing - probably a lesson in how NOT to take macro and will make the experts cringe. :oops::o...

I brought mine thinking they were AF, they are Kenko brand with "for P/AF" stamped on the side. But it was obvious when i looked at them that they don't have the AF screw drive :? So what does the AF stand for if not auto focus. :?

Usage problems K200D
I have a relatively recently acquired K200D. I've done a couple of shoots with models, and it's been great, except for.... Quite a few shots are out of focus. Quite a few times, the lens, whichever is fitted, seems to hunt for the autofocus, and then, when it finds it (or seems to) the shutte...

Usage problems K200D
If the shutter won't fire, it's because the lens is NOT in focus. You are presumably shooting indoors, perhaps with flash. The ambient light may well be fairly low, and if you focus on, say, the model's cheek, the camera will find it difficult to focus - it needs an area of high contrast. Try...
