I know this might be something basic, but I want to understand the following.

What is the difference between PL and Nikon lense, when used on RED, in terms of:

Field of view,
DOF

I mean if I both are set to the same parameters do I get the difference? How significant difference is it?

And also I read a lot about breathing, what is breathing? What does it mean?

I really appreciate any exlanation
 
breathing = when you turn focus right/left you see a very slight zoom effect = the image will get a little larger then little smaller in addition to going in/out of focus ...

24mm nikon ( that covers the RED sensor ) will have same DOF ( at same F stop) & FOV as a 24mm zeiss cine lens on RED camera ..
 
Hi Levan,

It's been covered many times on this board, but I'll give you the 10 second version:

PL lenses and Nikon lenses have the same FOV and DOF at the same stop.

Generally the optical quality of good examples of each kind will be good. PL is not a brand it's just a mount.

Still lenses are not designed with cine applications in mind. In some respects they will not be as user friendly for cinematography as cine "PL" lenses.

Breathing describes the focal length change of a lens while it's focused - it looks like a little zoom. Some lenses do it more than others. It has been intentionally minimized in the design of some cine lenses. Filming with a lens that breathes minimally opens up some creative options for the cinematographer, but a lens that breathes badly is not exactly the end of the world.

Hope that helps.

Donatello, Matt

thanks, that helps, but I got confused, I understand that when the lens do not breathe (not change the focal length) is good. Right?
 
Very nice works MATT on your webpage :*)

thanks

Is there a set of lenses you would recommend, with less breathing. I mean how can I know if the lens is breathing. :)

I think there are many other criteria that you should be concerned with beyond breathing... What are you planning on using the camera for?, what's you experience level? and how much do you want to spend ?

Thanks for the nice comments on my work.

well the my case is following. i am not a dp, and i own a rental company in a small country, Georgia. i have 4 cameras on the way and they are purposed to be rented out. i want to appeal to different users with different budget ranges. so i want to have different level of lenses for each camera. i own prime set of canon k35 pl mount lenses, so that is one. i plan to buy a set of cooke s4i for more advanced users, and for smaller productions i want to also go with nikon optiin on my other 2 cameras, as most of my clients are budget concerned. but i want to set the best available nikon lenses as even the most expensive nikons i expect to be cheaper than used cine lenses, or am i mistaken here? so best of nikons would be for me. so what would you recommend and what are the other things to consider.

thanks for info. and i watched even more of your works and sincerely footage is very beautifull.
 
I have ordered Nikon mount that is on the web page. I do not know if it is Birger Nikon or not.
 
Stills zooms would be something I would do some tests with before jumping on buying them. There is a good chance the focus hash marks will not track properly throughout the zoom. What I mean by this is that with lets say the 24-70 for example there is a good chance that an item that is 5 feet away when focused properly on the wide 24mm end of the zoom will not be in focus on the same spot on the lens focus when zoomed to 70mm. Cine zooms are built not to have that problem but some stills zooms have the problem. A stills prime lens will not give you that same issue.

Levan, if you ordered from the RED.com store, that's the manual Nikon mount, not the Birger mount. Many of us are ordering both, the manual one for non AFS Nikon and the Birger for AFS lenses. The Birger mount is ordered by filling out an order form. Read this and try to fax your order before the Dec.31st so you can get the free remote control:

If so would the Birger mount then make life a little easier since there is a quasi focus wheel.

Assuming the electronic focus motor controls on stills lenses are accurate enough to pull good focus, the Birger mount should solve the mechanical problems of focus pulling on photo lenses entirely. Are the electronic controls that good? I suspect they are, because photo camera autofocus mechanisms are obviously capable of making very fine focus adjustments, but I don't think anyone who hasn't actually tried to pull focus with a system like this can say for sure.
 
sorry if this still is not the very smart question, but is birger mount Nikon F mount or canon EOS? it is not the same right?

Anyways, thanks all for answers, a lot of info.

Birger is producing separate Nikon F mounts, Canon EOS mounts, and a few others.
 
so should I go with canon EOS? (in the reservation form it is canon EF-S)
