How good is Sigma 70-300 APO DG Macro?
Gentlemen, Not a good day for pictures. Overcastted and poor light. Just some test images with the Sigma 70-300 lens. Images just croped and resized. I think is not bad at all…:o The first macro... A piece of texture (macro). My everyday visitor out of focus...(at 300mm f...

Switch lens or switch camera
Back in my purely film days I owned piles of kit including FA* prime lenses and F2.8 zooms but despite that I still found the FA 28-200 to be a useful bit of kit - primarily for family days out where I didn't want to carry much kit and/or when my wife and kids tolerance for lens changing stops was a...

Standard lens or f/2.8 zoom?
I'm starting to think I need to get a lens with wider aperture for low-light shots on my k10d (only had it 3 weeks and already I'm almost buying more lenses :shock:) Currently I have the 18-55/3.5-5.6 that came with the K10d and also a range of lenses I had with my old MZ10 : FA 80-320/4.5-5.6...

Standard lens or f/2.8 zoom?
Thanks for the ideas - sorry for confusing people by saying I was looking for something wider - I meant aperture, not focal length. I think 18mm or thereabouts is ok. I've now been back and looked over a selection of shots I've taken with the 18-55 to see what focal length I actually used. Enough...

Standard lens or f/2.8 zoom?
One tweak that I wish pentax would do in a firmware update is to make the ISO value show at all times in the viewfinder in all modes (perhaps it could change back to shots left if under 20 left?). This is possible already in Av and Tv modes (I use Av mode almost exclusively). What you need to do ...

Old & New Lens for Pentax
Just to back up what I said above, a picture taken with the Tamron on my K10D earlier this week. This was shot at 260mm / f5.6 / 1-180sec / iso800 and has had no adjustments other than to be converted into jpeg in CaptureOne and then "saved for web" in Photoshop. Despite this not bei...

Tamron sp AF 90mm 2.5 Macro
I did have a Tamron 90mm f2.5 Macro at one point. It was manual focus. The only problem was that compared to the pentax lenses it was so enormous and so heavy. Quite out of context with all my other lenses, so I sold it on. In terms of performance though it has an excellent reputation. I know ...

Tamron sp AF 90mm 2.5 Macro
You have made a good choice Clarky, I have the excact same lens and I rate the optics as good as any of my Pentax glass, this is obviously not going to give you 1:1 macro so invest in a set of extension tubes and get snapping. I think I paid around £95 used from a dealer about three or four years a...

New PKA mount Zeiss Lenses
All else being equal, by introducing a new range of K-mount lenses, Zeiss will increase the supply of lenses Who are they targeting, do you think, by introducing such a range of manual focus lenses?

New PKA mount Zeiss Lenses
That's true of some lenses, like the FA* 200mm and F/FA* 300mm 1:4.5, but the FA 20mm and F/FA 135mm don't seem to command very high prices. I know, because I would like to sell mine! I seem to recall a A 20mm going for around £110 a few months back (not 100% sure on that). Never seen a FA 135, I...

New PKA mount Zeiss Lenses
I have to say that T* Distagons are probably the sharpest lenses I have ever used in cinematography. They utilise 'T' stops rather than 'F' stops; T being the actual light transmission rather than F which is a mathematical formula. If these new lenses are up to the same standard they will be stunnin...

New PKA mount Zeiss Lenses
Hi, Just one or two points on things mentioned in this thread so far: "Don't forget the marked focal lengths of all lenses are nominal. Most 24mm lenses from the MF era were closer to 25mm, so Zeiss could simply be making a slightly more accurate (or honest) statement" In the orig...

New PKA mount Zeiss Lenses
The Pentax 85/1.4 A* which will compete directly with the Zeiss ZK 85/1.4 is very expensive and will cost you just as much secondhand in mint condition (or near) as the Zeiss will cost you brand new, so I know which I would buy. But this (the Pentax) is an obsolete lens that few nowadays would cho...

Hi, G: "The true comparison is between the Zeiss (manual focus and exposure) and the Pentax 77mm Ltd. At B&H, the former is listed at USD 984, and the latter at USD 679" Cannot argue that the Pentax 77mm is superb, but it is not true that it is a 'true comparison' to compare the ...

31mm Ltd passed up for future DA* 16-50mm
I have the lovely 31mm and I have no plans for replacing it with a zoom lens. The 31 LTD is among the best glass I´ve owned (and I was a Contax/Zeiss user back in the film days). Primes "talk to me" in another way than a zoom and I really don´t know why. But one thing is for sure; The...

"Upgrade" at zero cost!
While I'm owning up to idiocy, a little warning about the K10D - which is great, by the way. For reasons I don't understand, you can set the part of the screen which it focuses on to various areas. When I first got it, I din't know about this and - somehow - must have set it for an off-centre spot. ...
