What don't you keep the old 300mm? As Jarred mentioned earlier, the "difference" is $5950

Thanks for the confirmation on the drop-in filters and the teaser with it sitting next to the Cooke. :) Hopefully I'll get mine by the end of the week.

I believe Hoya made 43mm filters that work on the other 300mm RED lens. But I guess I'll have to start researching that myself now.

Schneider Optics makes the best drop inn 43 mm filters (made in Germany by Schneider optics GMBH). Because the filters are between the image sensor and rear optics of the lens, it is VERY important that such filter is ground parralell and introduces NO optical magnification. If it does, your lens back focus will be off and so will all your footage marks. The clear filter that comes with the lens is installed during the lens back focus and footage calibration. If you remove it and not replace it, your calibration will be off........
Go to www.schneideroptics.com for more information.
 
Folks, I just checked with Schneider Optics USA and they don't seem to carry it anymore,Schneider Kreuchnach (BW) does not show them either but check with them anyways. Tiffen makes a few 43 mm filters. Check with them and make sure that they guarranty flattness (parralel-izm). B&H also shows a few 43 mm filters - not sure if they are screw in or what. I have not dealt with these filters for a while-everything changes.......
 
Should've had my filters today... But FedEx hosed me. I guess I'll get them friday now.

I agree with Camera Doctor's sentiments, but I know of several people using these Hoya filters with great results for the original RED 300mm. I'll see how they work out. I'm also in a bit of a time crunch, none of this info was available until I actually got the lens in my own hands. RED still has not posted or confirmed any specs. The Hoya filters are performance guaranteed. I went with a B+W pola for the front of the lens, I have always been pleased with with their filters. The Schneider pola was special order with about 5 to 10 days lead time, not accounting for the holiday weekend. The Schneider was also nearly $200 more. I'm still hoping that the filter will actually fit the front of the lens. I need all this because I will be running it without a mattebox next week on a shoot in the mountains. I'll need to bring as little kit with me as possible.
 
Jeff what are you using for support? I am waiting for Jacek at Optitek to get his support out, soon I hope.
 
I made my own support. Not quite as elegant as Jacek's one for the 18-85, but functional. Actually it's a piece of 3/8" aluminum that I bent to cradle the lens and I glued a strip of neoprene on the inside of it. I tack-welded a 3/8"-16 nut on the bottom of the aluminum cradle so I can run a a bolt up through a universal mount into the the nut and support it / the lens.

I'm interested to see what Jacek comes up with, I'm assuming it will be similar to the 18-85 support he's made. My support will work for now and I would trust it for most anything that isn't vehicle mounted.
 
Update...

Just got my 112mm filter for the front of this lens... Aside from B&H shipping me a filter that was obviously used by someone else previously and damaged :ranting2:, the thread size is wrong. 112mm is the appropriate diameter, but the threads on the front of the RED lens are a finer thread count than what comes on the B+W filter.

Anyway, gotta get this sorted ASAP... Otherwise I'll have to lug the mattebox and more filters with me and handle more gear.
 
I have not seen the pro version of the 300 yet, but know that on some lenses what appear to be threads for attaching a filter are in fact threads that are part of the manufacturing process of the lens. It is quite possible that RED never intended to have any filter screw into the front of this lens.
 
Good point, Mitch. I hope that's not the case. I have been so eager for a solution that I had not even contemplated that possibility.
 
That's the plan, but I figured I'd post here too... RED is officially closed until Monday, yet some of the RED team is online here. But I actually have Brent working on finding out for me -- he even emailed me late tonight just to say so. :)
 
Filter for 300 mm Lens

Filter for 300 mm Lens

There is a filter tray at the back of the lens that carries a 43 mm clear filter. This filter has "Normal" stamped on it. You can change that for a 43 mm - Pitch 0.75 filter of your choice. Just remember that you always have to have a at least the original clear filter in place or your focus marks will be off. I have used ND's and Pola 43 mm filters on the 300 and it works great.

One thing to be careful of is the original 300 mm had a slightly narrow clearance for the filter frame, it seems less so on the new Pro 300. I had some Hoya brand 43 mm filters that I had to carefully sand down the front of the actual filter frame to get it to fit in the slot of the first series 300 mm. I just tried one of those filters in the Pro 300 and there wasn't a problem.

In my experience and advice of many rental houses it isn't a good idea to stick filters on the front of lenses much longer than 250 mm or so. It degrades the image much more than a filter in the back.

This is the same that applies in Still Photography and the reason why none of the super telephoto have only a rear gelatin Drop in filter slot! Degradation of the image will be indid very apparent when you put a Customized filter threaded in the front of a lens like the 300mm, I know I have done this with a 200 IS 2.0L, 300 2.8L and the infamous sports fanatics marvel the 400mm 2.8L, when I didn't know better I wanted to put a filter in front in order to preserve the exposed lens, especially on lenses this expensive, I have an UV HAZE filter on all of my lenses, also because this is only when they truly become Weather resistant ( L series).

So no front threaded filter on lenses from 300mm and above. There many solutions including fairly inexpensive LEE filter systems which can be tighten on to any lens size.
