Sigma 150mm macro
I would need a 49-72mm step ring if i want to use my AF-080C You got me thinking sometime ago when you mentioned making a macro flash bracket but gave up when it became too cumbersome. I have a couple of dinky little AF-160 flashes and decided to make a bracket to hold these. (Not sure if these...

Sigma 150mm macro
P.S. Clarky, of course we promise not to laugh. :shock: :lol: Speak for yoruself. :-) Actually, having grown up in the wilds of Africa I am all in favour of a bit of DIY. If you need some advice or ideas, ask Don. Ingenuity is his middle name. G Thanks George, I think i have it all cover...

SDM Tele converters..
the connections you need are the Power Zoom contacts, not the normal data contacts. These are located inside the K mount on a sortof wedge thingy at the bottom right of the opening as you look into the body (I'd show you a picture, but I don't have my K10D with me). If you look in the MZ-5, it ha...

Pentax 1.7X Teleconverter
it's also the only Pentax auto focus compatible teleconverter, albeit AF compatible in a somewhat bizare fashion.

DA* 300 (or others) Advice Needed
With regard to Chirpy's question, wildlife and anything else, mainly at the long end that catches my attention. In the summer, many photoraphs are taken from a moving boat, where the subject matter is almost always further away than would be ideal, so even with a 300mm lens, cropping is highly li...

DA* 300 (or others) Advice Needed
Sometimes I'm so daft. :roll: Remembered today that at work we have an account with Intro2020 (the Pentax distributors), and with my staff discount I could get the DA* 300mm for about £800, so I'm much more tempted again. (P.S. It's advertised in the latest P.U. mag at £849 from Digital Camera Exch...

DA* 300 (or others) Advice Needed
Sorry John, should have pointed out the Tamron is the 300mm f/2.8, very much a 'top quality professional optic' (of its day). I look at the shots I get from it and from a sharpness point of view, I don't really see that it could be improved upon, it's certainly sharper (I think), than any of my oth...

DA* 300 (or others) Advice Needed
I'm not sure there's much difference in sharpness between them, once you stop the Tamron down a little. The biggest things for me are the obvious - weight, auto-focus, weight, SDM, weight, quick-shift focus and, oh, weight. That said, I guess it depends how you intend to use it. I wanted the DA*...

DA50-135, where's the problem?
Hi All I used my DA50-135 on a location shoot for the first time last week, now, I've had this lens for a few months but have not really used it much in anger, when I have used it I've been as much disapointed as happy with the results, I put this down solely to me, the silent focus takes a bit o...

DA50-135, where's the problem?
My DA*50-135/2.8 wasn't focusing accurately when I got it either. Unfortunately it was too short before a three week trip to Cambodja in order to have it looked at, so I tried to use it sufficiently stopped down for most of the time and it did great. Back home I tested a bit more and I confirmed ...

Pentax 75-300mm vs Tamron 70-300mm
I agree about the switches being fiddly, and I don't like the way the rear lens cap has to be aligned in just one place to go back on. Minor details but ones that detract from the user experience nonetheless. Having said that, for the money the Tamron's tough to beat! :)

I am so new to photography I do not really know what an extention tube or a reversing ring actually is or what they do. I have heard about them and seen them on EBay etc... but what they do, how you attach them and what results to expect is totally alien to me. Extension tubes are fitted between the...

what would this [50mm] lens be good for, why is is different to say .... zoom lenses? Like a lot of prime lenses, it has a much larger maximum aperture than you get with a budget zoom. This can allow a shallower depth of field (less of the scene in focus) or a faster shutter speed. It makes the vi...

I echo others comments really - as cash is a little tight give the 18-55 a good try-out & see how you like it, decent lens considering its price. The 50mm 1.7 is a good suggestion too, I bought one off ebay myself for very little cash, it's manual focus but great for portraits etc Main t...

A 50mm lens will be great for still life and also close-range portraits. The one I mentioned above is good for a low budget. If you want a little better quality and auto-focus, there is the Pentax FA 50mm F1.4. For shooting models a bit furher away, something around 80 to 100mm would be more su...

Here are a couple of random images (sorry, not very good ones, but give some idea hopefully). EM I think those photos are good, thanks for sharing those. Although I have tried and tested manual focus which is better for close-up work, I think an AF lens is the way to go for me for portraits. ...

its fast aperture will be a god send in that situation, but you will need to be quite close to the action. As long as the hall isn't too big and you're not too far back, it will be the best option in your price range. I also carry a 135mm F2.5 Takumar Bayonet for this sort of thing. It's manua...

Although I have tried and tested manual focus which is better for close-up work, I think an AF lens is the way to go for me for portraits. The 50mm is what is being recommended by several members here, so I'll go with that. I see the Pentax SMC P-FA 50mm F1.4 on EBay for £129 + p&p Is this...

Keen2learn, I think you are making a fundamental mistake. You appear to believe that all you need to make better photographs is more equipment. Not so. To make better photographs, you need more practice. You should be out there TAKING photographs with what you have. PS: Liked your "S...
