>Published : 8th November 2006

>I've got a commercial coming up shooting diamond jewellery. My experience with lenses is with film lenses on film cameras: macros and probe lenses. Where is a good place to start my research for lenses when shooting video (f-900/3)?

>Hi Ian

>We have a Pro-35 adapter that will enable you to use the film lenses you're accustomed to. Let me know if that interests you.

>There are also great HD Prime lens sets avail. I'll be happy to discuss with you. Just give me a buzz/shoot me a line.

>Zeiss 70mm Close Focus is sweet. Plus8 has those.
Innovision has a probe system [I'm using it today.] It's not nearly as clean as the Zeiss, but it's a probe.

>Plus8 also has a longer macro I think its a Nikon.

>Good luck.

>Hi Ian,

>This is not lens related, but with jewellery you will need to be able to capture as high dynamic range capture as possible – as you previously did with film.

>With the f900 you should consider looking at the Digital Praxis gamma curves (ok, it is a personal plug as I developed the curves to provide an extended dynamic range capture, allowing for better flexibility in post.

Have a look at the info at :

>Geoff has also posted some examples from a shoot he did with the different gamma curves on the CML website – do a search for CVP Gamma Curves.

>Steve,

>Already done! I am a regular user of one of your curves. In fact, I started using the gamma curve about the time they became publicly available on your website. Use it on all exteriors and many interiors. I've shot one short and a full length feature, and many commercials. As soon as I heard "diamonds", I knew the curve was going to be invaluable for the shoot.

Hello Ian :

It looks as if you have had some good responses to your lens inquiry but don't forget to get a good smooth servo turntable and some new black silk and black velvet for the top-o-the-turntable. Oh, and try not to let anyone pull a Pink Panther on you.


All my best,

John

>The job is done, and the decision went to the 70mm Zeiss close focus DigiPrimes. I tried to get a 1.4x but that did not materialize. At absolute close focus I got a field size of 2 1/8 inches, which was great for this job. In fact I was able to back off a little. The front element was still quite close to the rings, about four to five inches, but my gaffer was able to employ some great solutions to get very nice sparkles.

>The lens performance was, of course, incredible.
