Beginner Focus Questions

Hey guys I couldn't find an exact answer for this but I'm sure it has been asked many times before.

Okay, I understand the basics of changing the focus and zoom on a standard HVX. What I'm confused about is changing focus and zoom once an adapter is attached.

1) Are there any adapters that have the ability to zoom?

2) Once an adapter is attached how do you change the focus? Is the focus adjusted on the camera itself or on the lens that you're using?
 
1) Don't touch the focus on the camera once you have it setup properly.

2) You can zoom with the camera but should not back out further than the edges of your ground glass.

3) You adjust or "rack" focus with whatever lens is on the front of your adapter. Again, don't touch the zoom on your actual camera after it's setup or you will probably punch yourself in the throat when you watch your footage.
 
i think he did mean focus. Set your focus and then tape the ring down so you don't accidentally bump it out of focus.
 
I was kind of wondering the same thing. I'm new to my M2 and have followed the Redrock manual to set the "back focus" and the image is great, but now I only have a Nikon 50mm f/1.8 lens that doesn't zoom, so how can I zoom? Do I NEED to have a lens with a zoom in order for it to work?

You zoom with the camera. But I would even use that sparingly. Just move your camera closer to the object. That's what I do anyway. You do not want to use zoom lenses on adapters.

Kholi is exactly right though. Lock down your focus. Some people tape the zoom ring as well.
 
Alright I'm looking at 50mm Nikon lenses on Amazon now and there's this f/1.4 that looks good but this exact same lens at f/1.8 is $200 less! Is the difference between an f/1.4 and a 1.8 significant enough to justify the extra money?
 
Yes it is. go to www.keh.com and see what you find. I got a Nikon AIS used 50mm 1.4 for $80.00 it was not ugly. (you'll see what I mean based on their rating system) glass was perfect just some scratches and signs of wear.
 
I've heard the term vignette used often but I'm not exactly sure what it means. Are we referring to the darkening around the border of an image?
 
Can zoom lenses be used with a DOF adapter? Is it ever acceptable to use one/are there any zoom lenses considered acceptable by the adapter community?
