Hi guys, could someone please explain, why to use a 35mm DOF adapter (like the Letus Ultimate) in a Sony EX3 instead buying some lenses for that cam? I would use the dof adapt in a fixed lens camcorder. The whole rig plus adapter would cost as much as a good lens.

Hope someone can tell.

You get a shallower depth of field for a given focal length and F-stop using the DOF adapter.

The larger the imaging area - (the sensor or film frame) the less depth of field you get. The EX3 sensors are 1/2". The adapter ground glass is larger, usually full-frame 35mm. The EX3 sensor captures your image off the ground glass (instead of capturing it directly from the lens) and so gets the DOF characteristics of the larger imaging surface.

It shouldn't be hard to google a diagram of the process, which will explain it far more clearly than I ever could.
 
Hi Eric, thanks, so the camera just gets what the attached lens is capable along a "virtual" sensor (ground glass). Worth it the price in terms of sharpness and light loss?

Well, I've got an EX1, and I've thought about putting an adapter on it - they're very cheap now. But I'd say no. I haven't done a direct comparison, but I think the quality from a DSLR would be comparable. Depending on what you're doing, it's probably best just to go out an get a cheap DSLR (t3i or GH2) to use as a B camera when you need shallow DOF.

I guess color-matching might be an issue if you do that though.
 
You could buy an FS100 for all you will put into an adapter and lenses and all the gack you have to have to make it work---and it's cumbersome at best. DSLR's a pain for audio and again, lots of gack to make it a working video camera. Get a video camera with a big sensor and save yourself time and money in the long run. IMHO
 
Really, your best bet would be to purchase a GH2 instead of a DOF adapter. You're not gaining anything with the EX1's codec (essentially HDV+!) over what a hacked GH2 can offer, and both will give you around the same level of sharpness (this is why I recommend a GH2...it's comparable in resolution unlike the Canon's). Get the colors matched up with some tinkering and you have a much better (even possibly cheaper depending on which route you would take) solution to getting shallow DOF when you need it.
 
I guess ill keep my camcorder as it is and maybe add a teleconverter and a wide instead and take the shallower dof possible in some shots, in fact the deep dof will limit what i want to do but ill have to explore another narrative ways.

Gary, what do you mean with a "hacked GH2"?
