  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

I just saw this on the denz site, a new tool for setting the back focus, no idea of price but it's a pretty piece of kit for setting back focus on the RED, check out how it uses the on board monitor.

Nice! I have a feeling this is a lot more expensive than the Red Null.

For sure,but it's just such a beautiful design. I love the use of the monitor. Denz don't make aything that doesn't cost, a bit like P+s.:crying:
 
Saw Denz at NAB. Very impressive quality products. And I got the impression they are the manufacturer of the RED Carbon X rods..
 
I believe this device is about 3500 Euros. An excellent design, but it is an expensive device. There's room for everyone. The Denz FDC is useful for cameras that do not have an adjustable mount and instead use shims because the Denz measures how many microns off the mount depth is. This is useful for cameras such as the Phantom.
 
I just got a quote, it´s 3.285.- EUR ex works and should be available in August 09.
 
Now, if the exchange rate was something like it was a year ago that would be a decent purchase for me....but not any more.:cry:
 
I've always liked the Denz products. This flange depth indicator is very clever. They also (in my opinon) make the best S/B to PL adapter.
 
I wonder

I wonder

That is a very nice looking and well made device. I wonder however if this design will work well on cameras with OLFP filter glass. It looks to me as it very heavily depends its accuracy on the refractive index of the OLFP filter glass so if that glass changes or you try to use it on two different cameras with two different sensors the results will vary. Time will tell...

Jacek,

Wouldn't that be true of light coming from a lens as well? The refractive index would be a constant unless the OLPF was somehow out of parallelism or planarity to the sensor or mount. I'm thinking that on the whole it would be at least as accurate as our devices, just a whole lot more expensive!

Not if the lens is retrofocal telecentric design. The Denz unit project rays at an angle and uses their convergence point as reference. For different refractive index glass the convergence point will vary. When you project an image you see the sum of rays as the result. You also look at the center of image when the rays are(mostly)paralell. I'd love to verify this some day...

Great Product, Something that will save you time and money in the future. Checked it out at the NAB and been in touch with people at Denz. They have modified and made it ready for professionals.
 
Just wanted to bump this thread.
I'm still very interested in buying some kind of precision tool for setting BF. Not sure if this, the Null, or the Unique Optics Diascope is the right tool.
Anyone own/ and or use any of these?
Cheers,
Harry

There is another one , soon to be available. It has all the features that the others have plus many features that the others don't have and never will....

Make sure you watch the video- it explains a lot:thumbup1:
 
My priority is for a collimator which doesnt require any guesswork. Every time I lock down the mount of a Red camera Im squinting to see/guess if the depth has marginally shifted. The 1:1 image is just soft enough that you cant quite tell to the accuracy I would like. I really dont want to judge if a siemans star or line pairs are at peak sharpness on a monitor. Maybe my eyes are just getting old!

The Denz FDC on 'paper' seems pretty compelling. It appears to have the simplicity and accuracy to get the job done right.

Anyone tested it or know who the US dealer is?

I don't know about you, John, I've been servicing lenses for living for 20+ years and there always is gueswork involved- in any measurement. I'd used Chroszciel collimator(same principal) for many years and it's not 100% I can assure you. All tools require practice and experience. Optimator just gives you more information than others-for better or for worse...for some it could be too much
BTW I dn't know how they can claim patent wit Chroszciel as prior art...
