16X9 Nikon adapter for F3

That's pretty new, prob have to wait for reviews. It looks just like the MTF. Just a front Nikon mount (no secondary lock-down) and the red ring to operate iris. Pretty simple...not much to worry about, looks solid. Only difference to others is a secondary lock-down for lens which is kinda overkill away. If I was renting, I would maybe go for lock-down, for overuse.
 
I own the MTF right now but I am looking for an other option....The MTF is very fiddly, sometimes just zooming the lens changes the aperture. Does the job but i'm not totally thrilled with it. There is also the Prolock i looked at but for twice the amount.
 
The Optitek is the best. We had organized a group buy maybe 10 months ago and I wonder if Jacek would be open to another such buy if enough newer users were interested. It is really a superior piece. I dumped my MTF for it. Rock solid.

Same here. I had the MTF for 6 months and it got the job done but the issues I had especially what Nic mentioned were driving me nuts. Bought the Optitek ProLock last week and after just one day using it on a important job that I had to do a lot of zoom in, zoom outs(between shots) in changing light I instantly forgot the pain of the price. Only wish I had bought it in the first place. The 'PL' ish lens lock is fantastic and I can use it's smooth firm aperture adjustment on not just my Nikon G lens but on my older MF lenses that have click stops. They are all now cinematized so to speak.
 
I´m MTF owner a painful piece of metal with serious troubles (incredible amount of leaks) I´m looking another option, its time to open another Optitek buyers group!
 
I'm with you on that , would you be willing to start one?
The Optitek is by far the most interesting option.
 
Anyone know where I can buy the Prolock? I need it by the 15th. Was hoping one of the LA stores would have one, but can't seem to find it even on Optitek's website.
 
ProLock GB?

ProLock GB?

Hi guys,
Thanks everyone for a great feedback. We are honored to be part of such fantastic creative community.
Now for the potential group buy:
The way it worked out smoothly last time is when one person (GB Lead) keeps the tabs on the arrangement and keeps the GB post active until we reach minimum. Their reward for their time and effort is a VERY special deal on their (ProLock) unit:thumbsup:
Contact me off list and we get this GB started ....

Wow. I have the MTF and have had none of those issues. As for changing the iris with a zoom makes no sense..Are you sure your tstop is consistant though the whole zoom range? Is your hand touching the blue ring when you zoom? Iris is a seperate device that only moves if the screw from ring moves it...
 
Jason, trust me it happens. With my Nikon G series 17-55 2.8 (constant aperture, no ring) the torque of zooming can at times make the lens slightly shift in the MTF mount. When this happens the lenses "iris lever" that is in contact with the MTF's internals either loses contact or exerts pressure on it depending which way your zooming. This of course in turn changes the iris setting and exposure, usually about a stop. Now if the lens was 100% solid with 0 wiggle in the mount this in theory wouldnt happen. I've tried spreading the lens engagement tabs to firm it up but it eventually loosens up just enough to allow the slight lens shift when zooming.

To answer your question "Is your hand touching the blue ring when you zoom?" -Absolutely not. You can even screw down the set screw so the blue ring cant move but if the lens isnt rock solid in the mount the problem occurs. Like I said earlier, the MTF served me very well and in most situations, especially when using primes the problem mentioned above was a non-issue. Im now however DPing a series for HGTV and it requires a good amount of zoom adjustment and I cant have my exposure jumping around. For what it's worth, I told the Producer I refuse to do reality tv crash zooms while rolling. ;-) -Trying to film it more doc style.

What's my best option if I want to buy a ProLock and have it in LA by Friday?
 
+1 for Optitek, fantastic customer service.
Used it for a shoot with Sony Image Works, rock solid, looks good too ; )

Wow! I should prob look into a ProLock if that's where I'm headed with the MTF. Thx
 
The MYF mount has a locking pin that snaps into the lens. Until the pin is pushed back out, the lens can't rotate. If your lens is rotating when you move the zoom perhaps the lock pin was never seated properly in the first place or something has come loose on the mount. I mounted and tried to rotated my G zoom and couldn't get it to budge or change the aperture. I Also tried several AIS lenses with the same results.
