Tamron 70-350mm zoom question
Hello Ron, The only 70-350 f4.5 that I know about is model 05A and I'm afraid it is not an SP lens. Don't let this put you off though, Tamron simply do not make a bad lens and if you're happy with the size/weight and price, then go for it - it'll work just fine with your cameras! A few specs:...

Tamron 70-350mm zoom question
Ron, The lenses I have, have the model number stamped on or near to the aperture ring. Unfortunately, I can't see the number on the picture I have of the 70-350 but above the aperture window there is TAMRON, the zoom ratio and focal length range to the left and TELE ZOOM, BBAR MC and what looks lik...

Wide angle for digital
I am considering the jump to digital, however, before I do I need some advice on wide angles for these cameras. I currently use the 28mm FA on my film cameras for landscapes. I love the sharpness the contrast of this lens. I was looking for something similar for digital. Ideally I am looking for...

Wide angle for digital
I have a Sigma 20mm EX lens which I use with my ME Super and MX cameras. It is a lovely lens and the Lee filter system fits with the 82mm wide adapter. However the Lee lens hoods, apart from the very expensive wide one, will cause vignetting. Having said that, I have never experienced flare as yet e...

SMC Takumar / K
Hi everybody, first post but I've been reading for some time. I have a question, I have read many times here and elsewhere that the K lenses are basically identical to the SMC Takumars but with the K-mount. From what I could find, though, out of the normal and wide lenses, none of the SMC Tak's sh...

SMC Takumar / K
Yes, the 49mm filter size was abandoned for the K lenses, and then re-instated for the M series lenses. The early bayonet (K) lenses are pretty much the same as the SMC Takumars optically, in fact even unchanged from the Super Takumars. It is also true that some later Super Takumars were Super-M...

SMC Takumar / K
Hi, Both MXV and Ffordes are good sources for hoods. You may need to ring them first to check the filter size as they tend not to differentiate between the 52 and 49mm ones. The hood for the 35 and 28 K's were basically the same. The square one is more effective. For the 35mm, I find the best hood ...

lens filters?
You don't need to look for any special sort of filter for your lens. If it fits, it'll work, whatever the make. Alternatively, if you have, or intend to have, more than one lens (taking different sized-filters), buy a filter system, like Cokin. These are fixed to the lens via an adaptor. You t...

lens filters?
You would use a neutral density filter and (ideally) the slowest film you can find and the smallest aperature possible. Having said that, this will only account for a few stop's difference so it is unlikely that you will be able to take a 10-second picture at noon on a sunny day for example (at le...

lens filters?
Assuming you don't mind losing reflections, try using two polarizing filters. Obviously you'll be using a tripod, so line up your shot, then rotate only one filter until it blocks out enough light for your exposure. The two polarizing filters in series essentially make a variable ND filter.

macro lenses and reverse adaptor
Hi, The purpose of a reverse adapter is to use when you are taking photos at lifesize or greater as this gives a better lightpath through the lens. You will not get this sort of magnification even with a true macro lens unless you are using rings or bellows. The 50 and 100mm Macro lenses give abou...

macro lenses and reverse adaptor
Just a minor correction to Kim's post: The Pentax 50mm/f2.8 and 100mm/f2.8 are 1:1 (lifesize) macro lenses. That's one reason they're so expensive! The Pentax 100mm/f3.5 (made by Cosina, I think) is 1:2. Just to add another option - it is possible to mount a second lens back to front onto a mai...

which digital zoom?
OK - some advice before I spend yet more money I plan to buy a 'general purpose' digital zoom for my *IST DS. I already have quite a collection of 35mm glass from 19-400 - fine if I have my backpack but not if I just want to cary the camera and one general purpose lens (my Cosina 19-35 ain't bad ...

Problens, what problens ? Bring me solutions not problens !
Hi Colin, Here are a few disconnected thoughts, mainly based on my own Pentax interest which is the K and M era. Regarding sourcing gear, it's Ebay and the occasional camera fair for me. I would broadly agree with your statement that genuine manufacturer lenses are a better buy than third p...

bellows and extension tubes
The principles of photography are the same, whether you are using digital or film. Just think of digital as a different sort of film, but with greater control over processing. Up 'til and including the point where you press the shutter these isn't really any difference most of the time. However...

M42 - K Lens Adapter applied to the *ist DS
Hi Colin 4) Sorry not be clearer! If you attach a reverse adapter to the filter ring of a lens, you can then bayonet the lens in reverse onto the camera. This will give you a very close focus to the subject, in other words a high magnification. It will also deliver better quality this way round b...

Sigma 28-200 AF
I've seen a used Sigma 28-200 autofocus (KAF) lens available for sale in a local photograhic shop for £65. Its a stubby, chunky lens which takes a 72mm filter ring. The widest apperture was 3.5 or thereabouts On the face of it this looks a lot of lens for the price, but I've no experience of zoom...

Sigma 28-200 AF
28-200mm is a huge zoom range, so expect good sharpness but poor drawing (high distortion), modest maximum apertures, not a particularly close focus, very expensive large filter sizes. I would expect much better performance out of more modest designs.

Where can I get a 800mm fixed telephoto lens?
Before you buy a new lens, I wonder what sort of 800mm lens you have? In general, with such a long lens, there will be problems with sharpness because of camera shake. You would need a very solid tripod and high shutter speeds. At long distances aerial haze will reduce sharpness and contrast, ...
