  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

FF35 Cine Glass: Get Ready

ok, so let me see if I understand this correctly... a macro lens throw will be the same as it's non macro counterpart aside for the added rotation for closer focus, meaning the throw is identical only it keeps going a little bit more?

Not exactly,
Macro lenses have much longer focus throw than normal but, to simplify things, most of it is designated for macro distances which, unless your main work is miniatures and such, is useless to you. Macro feature also makes the mechanics more complicated and, consequently, usually more expensive.

hmmm... well that is certainly great to know now, in case we did get the opportunity to go that way it would blow if I later found out I had spent tons of cash on multiple macros thinking I was getting more throw for normal shooting

Ok, so here are two questions so I can continue bugging the crap out of u guys and beat this dead horse a few more times (I am telling you, he is not dead, he is just napping):

1. Is there any other still glass that you guys know of that has above average focus ring action which should be considered for motion?

2. Is there a particular FF that has taller gear than the rest?
 
The mechanics on the Leitz (Leica) lenses are very percise. The Zeiss lenses made for the Contax cameras were very good and most focused cinewise eliminating the need for a reversable follow focus unit. I believe this holds true for the Leitz optics also.

This store has some nice examples of the Contax/Zeiss lenses. Not the cheapest but nice ones. Including the amazing 21mm f2.8, 55mm f1.2, 85mm f1.2 the wonderful 200mm f2 and the 60 and 100mm macros. While not shown here there was also a 28mm f2 that is quite nice.

And of course they cover FF35 (24x36mm) if you decide to go that route.

This is correct. The Contax/Zeiss 60mm and 100mm macros are both 1:1 and can be converted to PL mount or rehoused, they are great macro lenses. In their stills form the front of the lens extends which you may of may not be able to live with and using an FF unit tricky. The Leitz lenses are not 1:1. The 60mm can use and extension tube to get 1:1 and I've seen one extension tube modded to PL so the lens it self does not require modification and retains its R mount. The Leitz 100mm 2.8 uses an additional lens for 1:1 so I don't think an extension tube can be used in the same way to mount to PL. An expert will need to comment on this if possible.

The Leitz 60mm is usually 30% less than the Contax/Zeiss 60mm price but the 100mm Leitz is about 20% more than the Zeiss macro. The 100mm lenses being more expensive. The Leitz 100mm is said to be the bench mark macro. Ffordes photographic in the UK have all lenses used at reasnoble price, ( I have no connection to them but have purchased from them before and found them to be very reputable). If you search hard you will find the Contax/Zeiss lenses for £200 to £400 each in near new condition. Les Bosher can convert them to PL for you or you can use a convertor to Canon EF if you have a Canon mount on your camera.

What Dave says is true. I would not worry to much about racking focus with the macros you don't need to do that to often and it can either be done by hand or a long gear can be made to fit you follow focus unit. The way it was done before internal focusing came about on lenses (think Angenieux 25-250mm zoom etc.) I just pointed out those exotic lenses as an example of what can be had in the Zeiss/Contax line. As Dave said you can get a nice 50 or 85mm f1.4 version $400-$600. And yes the macros are nice.

Don't worry, me neither(so typical here):bleh:

I don't think what Dave or I said can be put much simpler. Don't try to wear to many hats and let your cameraman guide you along.
 
^ yup... the problem is that I am line producing this project, and that's the only way I am going to get to direct my first feature :weight_lift:

(BTW, just to clarify, once we start production I am getting a UPM to do that work)
 
OK, Guys. I decided the other way around :usd:

A brand spanking new Canon 50D and a PL mount have been acquired and are on their way to an experienced "surgeon" to create the first DSMC operation :w00t:

The surgeon will carefully remove the disfunctional EF organ from the patient and make a PL implant in its place.

Can't wait to see some night time lapse at 14mm wide, f/1.2, 4.8k and almost noisless ISO 3200.

Very interesting, please can you let us know how the engineering goes.....
 
Take care as many lenses will be hit when the mirror moves (unless you cut some of the mirror away, the Leica rangefinder camera can be modified for PL glass more easily.

adapter

adapter

Since PL mount's flange-focal-depth is larger than canon EF-mount's woudn't a simple adapter work? Changing mounts sounds more diffucult that making an adapter and you could still use EF-lenses. Or would it be difficult to build an adaptor sturdy enough for heavier PL-lenses?

I think the problem is both the EF and PL diameter is the same, 54mm, so you cant make a PL to EF adapter work. I tried to find someone who could make this happen but didn't find any one.

Please could a lens tech provide some advice here ?

If it is possible count me in to buy one. This was raised in another thread and it god a lot of interest.

Just got the answer from Zeiss about their lenses' coverage, and indeed all of them are good to go:

"Dear Mr. Lequeux,

Thanks for your request and your interest in our products.
Yes, all of our current SLR lenses (ZF, ZE, ZK, ZS) cover the full 24x36mm image format (film or sensor).

Best Regards

Bertram Hönlinger"
 
Pawel,
Very impressive, bold (and expensive) experiment! Keep us posted.
Cheers,
Harry
