Alright, i am researching 35mm lenses right now for my dvx 100b, and i think i am going toward the letus based on what everyone on this board says. I have a couple of questions about the lens and i am sure that you guys should be able to help me out. First, is the lens hard to operate? I know it is probably a stupid question, but i dont want to buy something which is going to take my time to learn to use. Also, i am was going to film sporting events where your subject is moving quite a bit, is it harder to keep them in focus with this lens? Next, i would like to use it on a camera jibb, but would it be to hard to keep the focus with this lens? Next,i buy the lens for my 100b, will it fit on an hvx200 if i bought one later down the road. And lastely, overall is the Letus lens worth the money? Thanks for all the input you can give, and sorry if i sound clueless about the subject.

I wouldn't recommend using a 35mm adapter for your purposes because it would be very difficult pull it off, especially on a jib. I would just use the camera lens for your type of work.

Shooting sports with a 35mm is defninitely a challenge but doable if you are willing to put the time into practicing.

Here are two examples I did, one at a Little League game and the other is just an example of shooting with the Extreme at a high shutter speed at a kids' soccer game. Both have been posted here before:

This first one is a really big file:

I agree that you should stay away from using a 35mm adapter with a jib. Use the camera's built in lens for that. Try to shoot wide as much as possilble with the iris closed down so that you will have a deep depth of field.

I figured it would be hard to shoot sporting events. I forgot to mention that the main reason i wanted the lens was because i want to get into shooting music videos.. Im just kinda of hesitant to spend the money and then not like the lens. Thanks for input guys

I noticed that yo keep calling it a lens, but it's an Adapter that allows you to use many different lenses, No lens is included with the Adapter.

I'm busy making a remote follow focus for Jib arm use. Most people don't take the time to think about focusing.

See that guy beside the camera operator? He pulls focus. All freaking day turning that focus knob. Most people forget about this critical function.....

Adapter or Naked camera: be willing to lose a jib shot without an external monitor. It's very hard to judge if you're going high and can't be at the little LCD the entire time.

Even worse with an adapter and NO remote follow focus.

I think you would be served well to read this board for a little longer before you make your purchase. Not to be mean, but you don't seem to know a lot of critical points for owning/operating an adapter and they are not cheap.

And nothing will be "worth" it if you don't take time to invest yourself into it. To think otherwise is ridiculous.

We did an afternoon of jib shots here using the HV20/Brevis35 (jib), and XH-A1/Brevis (tripod). The HV20 was inverted mounted on our carbon rails with a 24mm f2.8 (to keep weight down). That lens provides infinity focus beyond 10 feet so for wide shots it's set at infinity, and for closer shots, we just set the lens using the focus marks (after it was properly collimated). One could argue that a bare camera would do just fine for this, however the production was being shot with 2 16mm cameras, 2 Brevis rigs, and an HVX on steadicam. We were trying to keep the look consistent with the 16mm film, hence the two Brevis rigs.
