Polariser or not - Sigma 10-20
When I tried it out on my 10-20 the polarization ranged from 100% on one side of the frame to nothing about 2/3rds of the way across the frame, where it started back in gradually... Made for some interesting effects, maybe even usable for some creative shots, but not what I wanted at the time, so...

Macro Advice/Tutorial to get the best out of S-M-C Macro Takumar 100/4
You do need to get more light. And extension tubes if that was the closest you could focus. The picture was taken at 800 ISO. For quality, try not to go above 200. The shutter speed was 1/30, which is slow (I can't tell if SR was on because some of the EXIF data seems to be missing. Best to...

Macro Advice/Tutorial to get the best out of S-M-C Macro Takumar 100/4
While I lack the patience Clarky has for chasing down critters, I do own a 100mm 2.8 macro, and manage some nice ring shots, reflections off droplets on champaine flutes etc in my wedding work. tripod, ringflash, off camera flash, homemade reflectors/difussers..... I use my lens primarily for ...

Macro Advice/Tutorial to get the best out of S-M-C Macro Takumar 100/4
Thanks for all your advice, I do have a Jessops bounce flash that I picked up when they were cheap so will try constructing something to diffuse that. I've searched around and there are some really interesting looking contraptions but for simplicity I'll try wrapping a load of bubble wrap round i...

Tamron teleconverter question
I just picked up a Tamron-F 2X Pz-AF BBAR MC7 Tele-converter for cheap. Haven't put it though comparison tests, but it seems OK at first sight. It appears to have pass-through for all electrical connections but my DA* lenses lose auto focus. Any one familiar with this tele-converter and know if...

Tamron teleconverter question
My older lenses AF just fine with the screw drive. here is not even any sound. When an SDM lens is mounted, the camera is already in MF mode so no focusing is even attempted. Went looking up the TC I found that I paid a little less than half price of the cheapest price I've seen. So not too ba...

Tamron teleconverter question
I have the Tamron 1.4x MC4, works fine with SDM on the K10 & K20, just hunts a bit more! Funny thing though, just tried it with a recently acquired Sigma 100-300 F4, and (via the screw drive) focusses better with the TC on!! On it's own at 300mm it does seem as though it moves so fast that it do...

Tamron teleconverter question
he, he, tried the 2x on my 28-300 lens (not a great hunk of glass to begin with by any means). No luck auto focusing with that lens. The mechanics function but there is no way for it to lock on at f5.6 plus the two extra stops added by the converter. The focus ring has such a short range to begin...

Pentax SMC P-FA 50mm F1.4 - any opinions?
I have seen this lens advetised on eBay for around £130-£140. I'm looking to use it on my K200D as a portrait lens. Anyone had any experience with this lens? (I'm assuming it's auto focus) Ta!

Pentax SMC P-FA 50mm F1.4 - any opinions?
he, he, do a search and you'll probably find dozens if not hundreds of comments on this lens. (probably more than you'd want to wade through) I hear the f1.7 is a tad bit sharper, but I believe I would be more than safe in saying you cannot go wrong with this lens. (you don't always want tack shar...

Pentax SMC P-FA 50mm F1.4 - any opinions?
The Pentax FA and F lenses are/were auto-focus, and the former is available brand new from SRS as stated. You would be mad to buy a second-hand one for just a few pounds less. Traditionally, 50mm lenses represented the pinnacle of the lens designer's art. Virtually none are bad, and that is par...

Pentax SMC P-FA 50mm F1.4 - any opinions?
This weekend I took my new 50mm FA 1.4 out for a real spin for the first time at a friends wedding. It is without doubt the single best portrait lens I have ever owned or had the good fortune to play with. The focal length is perfect for individual or couples portraits, or head and shoulders for ...

It all depends on a few issues. - Distance from the subject - Outdoor vs Indoor shots - Lighting conditions if indoor - Type of animal (big/small/very small!!!)(Fast/Slow/Turtle) - Time to focus on the animal - Budget - Photographic Knowledge - Equipment in use I believe you have just w...

Pentax Kaf3 mount
I think folk are making too big a deal over this issue, users have been happy to use KA lenses and focus manually so whats to stop them manually focusing a KAF or FAJ lens in preferance to disposing of it? I agree with John, Pentax have to move forward and I personally think we have been extremel...

The long and the short of it
how do you rate the performance of the 55-300mm? Is it better than the 75-300mm that you bought off me some time ago? I would say so, although I'm a bit short on hard evidence. The 55-300 definitely feels much better. It's midway between the weight of the 75-300 and 80-320, and feels much more s...

you know, I'm looking at my robotics project, and my 28-200.... and I'm thinkin.... (grab your fire extinguisher).... wouldn't it be great if instead of simple mechanical linkages on modern zooms, you could have an electronically controlled machine that'd grab a selection of lens elements and line...
