DA* 50-135 comparison
There's much more to a lens than the figures will tell you, and pictures of dark streets and teddy bears won't tell you much more. Not disputing this, but... I'd prefer to judge a lens on the basis of portraits (skin tones) and outdoor pictures in sunshine. This is all very well, but they're ...

DA* 50-135 comparison
Otherwise it's back to all this mystical subjectivity, and it's impossible to distinguish whether the Emperor has clothes on or not. I thought that's what you were getting at, but it isn't really mystical. It's just a very complex subject and in photography we are talking about a creative process th...

DA* 50-135 comparison
I wonder if it is even worth testing. any tests using af would be moot (af can be fooled), manual focus would require precise measurements, (not possible on poorly marked zooms) with specialized equipment like lasers. I'm refering to testing your lens, to learn it's charactoristics as they apply ...

Second Lens
What you'd be better off doing is getting a FA50mm f1.4 for low light/soft shots to compliment the 16-45 and the 80-320. I don't think the gap would be that bad at all. Most of the time you can either step forward or back for that slight gap in FoV. 45 on 1.53 crop is 34.9 degrees FoV 80 on 1.53...

70-200 f 2.8 range ?
Never used the Sigma so can't comment on it but I've had the Tokina ATX-Pro 80-200 F2.8 for many years, using it on film and digital, and I think it's an excellent lens. Build quality is superb (it's built like a tank) and optically I've had no complaints, including when used with a 7-element 2x TC....

Tamron 90mm F2.8 Macro Lenses
Apparently, the Di lens "weighs 15 grams less and is 2.5mm shorter than the previous model." :D Not sure that's a good reason for an extra £30 though. Generally the difference between 'digital' lenses and previous models is: 1) Special coatings on the rear element to absorb any ref...

Extension Tubes
Do you think this is a reasonable price for these extension tubes. I maybe missing something here as the item description says manual focus only but i can clearly see AF on the 31mm tube :? and they appear to have all the metering contacts.

Extension Tubes
I would say too expensive. I'd agree with this, if it is manual focus only. I cannot be certain but they look very much like a set I bought years ago from Jessops. ie not Pentax brand. They did not fit very well and got stuck...i threw them away. My experience with a set of Jessops PK/A tu...

Extension Tubes
The 13mm tube says it is manual focus. I'm not sure this is a matching set. I have a set of Soligor tubes, AF. I hardly ever use them and am considering selling them. I have only used them a couple of times, and decided they are not for me.

Extension Tubes
I have a set of Kenko tubes. They have an AF suffix and claim to be AF tubes. This apparantly means that they can be used with MF & AF lenses, but in manual focus mode only. Manual focus is no big deal when shooting macro, in fact, I and many others prefer it.

Pentax SMC-M 50mm f1.7
I've bought a few Pentax film cameras to scratch an itch. Each of them has come with a Pentax SMC-M 50mm f1.7 lens, but in general I use them with my f1.4 or f1.2 50mm lenses. On a whim, I decided to use the f1.7 lens and was very pleasantly surprised. Very sharp, and beautiful out of focus prope...
