I really wish there was a comprehensive list somewhere of parfocal lenses.

The E mount and A mount lenses are the only lenses that work with AF, am I correct?

Thank you again Bill for all the info. It's nice to find people willing to help :)

I am told that A-Mount lenses, using the A to E Mount adapter are very slow. The AF works but it is slow.

Also there are 3rd party adapters in the works (two) that will have full electronic compatibility with lens and body, so this could also include AF.

The FS-100 has iris control within the camera, not on the lens, so many adapters will work with exposure changes but no auto-focusing.

Most of us do not use AF anyway.

Yeah, auto focus isn't a big deal for me. The only time I use it is on ENG type shoots and I just use the one push button to grab focus when I'm zoomed out.

I really had wanted to upgrade to this camera, but now I'm thinking for my type of work I may not be able to until I can afford it + a decent zoom lens. I find even in interviews I need the zoom lens, to zoom in at crucial points. I know I can do a zoom in post, but I don't like to overdo it since I'd loose so much resolution.

Will only servo zoom lenses work with a zoom controller like a VariZoom? Also, since my XH-A1 has a servo zoom, is that why I can't control the zoom and focus simultaneously? I know... way too many questions >< haha.

Thanks again for everything.

The FS100 has a lance jack. The removable handle is a lance controller. I am not sure but i think the stock lens works like a traditional camcorder lens.

I think you mean LANC.

I never use zoom in an interview and most of my films are interviews as a doc maker.

Focusing is critical in interviews - it has to be perfect and most zooms do not hold focus if you change focal length by zooming. I never advise this. I stop the interview during questions and change if I really have to.

The only time I need zooms is when we are moving from exterior to interior which happens fast on location - then I am stuck with a lens change ... so zooms really help - especially aa wide angle zoom.

I don't know which zoom lenses you've been using, but any cine or ENG video lens will hold it's focus assuming that the back focus has been correctly set up and there isn't a fault in the lens. Some focal lengths may be shaper than others, but they're not out of focus.

Here are some of the PL mount options:

I agree but I did not think we were talking about cine lenses here or video lenses - mainly still lenses where the majority do not hold accurate focus during a zoom - well not for interview work anyway where I use a more shallow DOF.

Yes, very few still zooms are parfocal. Here's a list that one rental company suggests:

This could be the perfect solution for e-mount cine style lenses ...

Zeiss Baby Primes with e-mounts. They are based on the Zeiss CP2's. Available end of July.

P+S do their version of the Zeiss lenses.

Others that don't get mentioned are the Contax Zeiss lenses.

http://www.contaxcameras.co.uk/slr/slr.asp

These were modified to fit on Aaton 16mm film cameras by having the Contax mounts changed to Aaton. Unfortunately, they can't be used on PL mount, but an adapter will allow the Contex mount to be used on FS100. The click stops were still there, but in practise it was never a big deal, you just set the stop like any other cine lens. You can get gear rings made for them.

Well one "El Cheapo" lens which is worth it even if its only to act as a dust cap, is this:

Sony SEL16F28 16mm f/2.8 Wide-Angle Lens - E Mount.

I just picked a brand new one up on ebay for $165!!

I saw footage with this lens on a FS-100 attached to a helicopter and it was superb.

Having got my FS-100 set up now ... old Nikon lens popped on there ... my first reaction is ...

This feels very flimsy. I havent heard any comments on the camera's robustness so I was unaware but the camera feels like very thin plastic everywhere... it feels like you can snap anything off... even the LCD. I film on locations in some tough places so I am concerened .. dust, rain ... this will not stand chance. Even my camera bag is not enough protection I think... it needs foam and a pelican case. It does feel so weak. I am used to magnesium and aluminum I guess.

I like the camera. I like the image. I like the controls. But I do worry it will not last one shoot where I go...... and forget about heavy lenses ... cinema lens? Please!! I have changed my mind completely on that score.

I cannot imagine anything more than 2Ibs on this or a matte box without massive support.

Just a first concern - maybe I will relax once I shoot.
