The km 28-75/2.8 is almost the same as the tamron 28-75/2.8, optical I couldn't see any difference. The only obvious things are other marking and grip.

I'm very happy about the tamron. To avoid quality problems I would test before buying.

Thanks

Hi David Would a upgrade from a older Sigma 70-200 APO EX give visible better quality or better handling? It would give a shorter minimum focussing distance (from 1.8m to 1m) and HSM (quieter). Would it be faster focussing on a A700 / A900? Anybody some idea? I'm curious if it would give a better l...

Hi After (or while) buying the FS-1100 clone you can either buy a radio trigger or a infrared trigger. I strongly suggest using radio and there a cheap ones that do work, esp. inside a studio setting. They have special receivers using mains supply, but I think it could be more versatile to use one o...

I have got the download link on dpreview forum on my side. I will try to investigate the exposure issue in Bibble. I was surprised too that there is only the 24-105mm that is in the list of the corrective lens system of Bibble. Is this corrective system really efficient ? Hi I checked and after usi...

Hi Just get a FS-1100 clone and a wireless flash trigger and studiowork will be work perfectly. The FS-1100 clone will cost you about 15-20 euro's and a wireless trigger is nice to work inside a studio. BTW. Except for the FS-1100 the "problems" are the same with all other modern camera's.

Hi

Don't forget to gel you're flash or strobes. Adding a CTO or 1/2 CTO filter (like from LEE or Rosco) is cheap and give you a better color temperature balance with the interior lights.

I would be surprised if a Dlite-2 doesn't has the power to light most houses.

hugin, Gimp, Raw therapy and Ubuntu 8.10 (or the sooner 9.4) and you can build a very power full system in Free license (instead of working with cracked software :oops: ) Unfortunately, when I checked them out, the free programs like hugin can't use a good method to automatically stitch without usi...

Hi

You could try the stitching with autostich or hugin, I expect less distortion.

I was planning to just shoot cRAW, the only problem being that I cannot view them on the Asus, but to be honest it would be painful on the small screen, not to mention slow. I don't know about the A900 cRAW files, but the free Faststone program works fine on my Asus EeePC 900HA (WinXP) to view my A...

Hi

Has anybody experience with a translucent deflector inside a softbox?

Does it make the light softer and how much stops are "used" by it?


BTW. It's partnr 26305 from elinchrom, there are also gold and silver deflectors.

Hi

My first impression is fast, fast and fast. B5 is very fast for culling and selecting pictures.

I haven't got the time to compare the IQ, but it's clear they have quite some work to do in most area's.

A tilt lens allows you to have shallow depth of field with the plane of focus angled to the film plane. Image stacking can do exactly that, too. Of course, with a tilt lens it's easier to accomplish and will also work with moving subjects. I'm fully aware that plane of focus remains parallel to the...

Hi Has anybody experience with software to stack multiple images to get more DOF. This could be an alternative to using a (expencive) tilt lens. A free example http://www.hadleyweb.pwp.blueyonder.co.uk/CZP/News.htm Alain I've played with CombineZP a little and it certainly works as advertised. Whil...
