Letus35 Flip and vx2000/vx2100 setup

Hello,

I have the letus35 flip w/ canon 50mm f1.4 lens. Is there anyone else with this setup that can assist in the setup? For example, I removed my uv filter from the cam and attached the letus35. I did this because the uv filter and the letus glass was really close. I then attached the canon lens. The questions I have are:

1. are there specific focus settings on the vx2000/vx2100 and canon lens to get the best focus DOF?
2. What's the best aperture setting to use to achieve the best results?

My current findings are that I have had to adjust both the focus on the cam and the canon lens. Any suggestions would be most appreciative.

Thanks,
Troy

focus your cam onto the ground glass.. then dont touch it again. your camera's lens is recording whats on the ground glass.

Andrew, I'm a newbie when it comes to adapters, so can you break this down for me.

Thanks

Troy, every adapter is similar.

1. Mount adapter to cam.
2. Attach 35mm lens.
3. With unit off, (where applicable), set 35mm lens to F8 to F16, and aim at very well lit scene.
4. Set cam to manual focus mode, and focus on grain of GG. Set this and make sure it does not change.
5. Set 35mm lens aperture to wide open and zoom to frame your adapter's image properly (so it fills your view finder). Stop down 35mm lens again and make sure focus is sharp on grain of GG.
6. If you are planning on shooting with a higher F/stop, you may need to reframe (zoom in a bit) to avoid vignetting.
7. Now focus with your 35mm lens only. If your camera's manual focus changes, all of your footage is toast! I'd suggest attaching ND filters (unless light loss is high with the adapter) to the 35mm lens to keep the video cam in the F5 to F8 range. If you are using the built in ND filters on your camera...you're likely overexposing your GG....and that's not cool.

Hope that helps.
