K10 general purpose zoom choices.
My usual kit consists of the 12-24mm, 16-45mm, 50mm and 50-200mm Pentax lenses, all DA apart from the 50mm which is a manual focus A. I do have a 24-90mm, but the above line up doesn't really need it. It stays on my MZ3 for those rare days when I shoot film...

K10 general purpose zoom choices.
Adding my bit about the 24-90... This is an expensive lens :D SRP was around £450. Echoing George's thoughts, as a single lens solution, it's wonderful - giving about 35-135mm angle of view. Lovely bokeh and very sharp. In fact, I used it recently for some head and shoulder portraiture I was doin...

K10 general purpose zoom choices.
Concerning longer lenses, I have a tamron 70-300mm and was wondering if would be worth getting hold of an 80-320 instead? The things that annoy me about the tamron are its softness @300mm and its painstakingly slow focus. :roll: Would the pentax be sharper and focus faster or is it simply the body ...

K10 'shift and tilt' lens choices(?)
"........I would've thought the maths were fairly straight foward... " You may well be right,.......one of the numerically dyslexic here I'm afraid!! However, while it's easy enough to correct perspective digitally in the editing software it remains impossible to alter depth of field...

K10 'shift and tilt' lens choices(?)
Hi Viewfinder, Don't forget that with the much smaller sensor, compared to 6x6 or sheet film, you'd get much more depth of field at all apertures anyway - if you want the tilt to maximise DoF that is... If you're looking to use it to control the plane of focus to minimise DoF, that's a differe...

K10 'shift and tilt' lens choices(?)
Hartblei do a number of tilt-shift lenses in K mount, available new from a couple of sellers on ebay or presumably direct, though their website is quite out of date. I have an ARSAT 85mm tilt/shift which looks to be a similar design to the ARAX. The focal length is too long for architecture, but...

Macro Lenses Advice Urgently Needed Please
The best focal length for macro, assuming you want to take pictures of bugs, is 200mm, but these lenses are not cheap. The Pentax A* and FA* 200mm macros are especially fine and stratospherically expensive. Further to this, I am using an old Tamron 90mm SP with 2x flat field converter to give me ...

Lens
I have just got myself a Pentax K100D and I was hoping to use lens from my old Pentax KM, the standard lens of my KM fits all right, but I have a Vivitar 75-205 zoom that I use on my KM but it will not go on my K100, the problem seems to be a skirt at the camera end of the lens, where as the standar...

Is there a definitive guide to Pentex Lenses
Hi, I've just bought a Pentax K10 (actually a Samsung GX10), and am new to DSLR photography. I'm new, but technically minded. It's a been a week since I got the camera, and I've been through 2 books already. I'm after a fast lense, to take fast wildlife photography. The lenses provided with the G...

Is there a definitive guide to Pentex Lenses
There are innumberable threads on this issue, if you care to search. But briefly, all Pentax K lenses fit on all Pentax DSLRs. The K10D will work with all of them, but has problems metering with the early lenses (M & K), and has to be used in manual exposure mode. The good Pentax K lens...

Is there a definitive guide to Pentex Lenses
there are 4 basic generations of K fit lenses 1) no electric contacts, manual focus (Pentax K and M series are examples) 2) with electric contacts and A position on aperture ring, manual focus (Pentax A series) 3) more electric contacts, A position on aperture ring, auto focus (F, FA and D ...

Is there a definitive guide to Pentex Lenses
This is a great post. It should be posted permenantely somewhere. So it's apparent that the fast zoom is way out of my league and price range. I think I'll take Matts advice, and go for a slower lens and set the iso high. I have 2 questions though. I have my eye on a ... Sigma 100-300mm F4...

Is there a definitive guide to Pentex Lenses
Another thing, there's a good desciption on Wikipedia, says the following: The "crippled" KAF mount is used on the MZ-30/ZX-30, MZ-50/ZX-50, MZ-60/ZX-60, the *ist series and recent K series digital cameras. The only difference between the regular KAF mount and the crippled version is th...

Is there a definitive guide to Pentex Lenses
Yes. But, it won't meter very well. And, you really can't focus quickly enough on wild birds with a manual focus lens. AF is pretty much obligatory, so that cuts out older lenses with exposure complications. If, despite that, you do buy a K or M lens, then you can use it at full aperture i...

Macro-Sharpness:Pentax DFA 50mm vs 100mm vs Sigma/Tamron.
As Daniel said, the ultimate macro lenses are the two Pentax 200mm versions. The SMCP-A is manual focus, whilst the SMCP-FA is AF. Both are superb, and considered by some to be perhaps the best lenses ever made by Pentax (though others reckon the 77mm takes that crown, whilst the 85 1:1.4 lenses a...

Macro-Sharpness:Pentax DFA 50mm vs 100mm vs Sigma/Tamron.
hey guys I have bought the DFA 50mm macro before 4-5 months and I am very pleased with the results . I don't know if it is better than the FA 50mm macro but they should be on par . I heard that 50mm DFA lens is better than the 100mm . Never done true tests . There are two reasons I prefer...

Sorry I mentioned the 200mm now. :roll: :D I want the ultimate in 1:1 macro. I heard 50mm are more sharp than 100mm. I don't care for insects or bugs , thus I dont care if the min. distance is 20 or 30cm. I just want the ultimate 1:1 macro lens That does say you want the ultimate macro lens (tw...
