View Full Version : Mounting a 14" Commercial Ektar?

I picked up the front and rear elements from a 14" Commercial Ektar without a shutter. I was going to use the front in my Hybrid Voigtlander Euroscop. I oppted for a +1 diopter that gave me a nice 18" Voigtlander. I made some stops for this lens and I shot it a F-16, 32,and 64. They all look good. Any ideas on what to mount the Ektar in? PVC pipe with a waterhouse slot? An old brass barrel? I'm open to ideas seeing the success I had with the Voigtlander. I don't think I can find a Universal #5 shutter and if so it would be costly so give me some ideas please. Thanks.

1) If someone who owns one in shutter and owns an analog or digital caliper and can tell you the front to rear cell spacing (overall barrel length), that will give you a good target and reference.

2) I have been considering having three 1/4" aluminum plates machined the same size and tapped on the bottom edge, then milled for lens cells for a 12" Metrogon. The middle one would be for an iris. The three rigid plates would be moved around like on a lens bench. Alternately, a metal rod or two could be used as gages to set the spacing for symmetry and then make changes from there. This solution of course depends on having a machinist available who doesn't charge you what people usually get charged for such work.

Another option is masonite, a hole saw (I use an adjustable fly cutter instead of an incremental one) and set the cutting blade with a digital caliper and a test drill (not a hole, but just the initial cut to where the diameter can be checked with the caliper again. Spacing set by shims of whatever material works, and end to end thickness with the caliper of a micrometer. Centration of the cells is the challenge here.

The barrel for a 14 inch Ektar is 50mm long. You could just ask if anyone has a barrel sitting around since they remounted into a shutter.....

What you want isn't a normal #5, get one that says "Made for Eastman Kodak" IMHO it is worth putting a 14" Commercial Ektar in a proper shutter---these are beautiful lenses. You might contact Carol at Flutot's and see if she's got one.

Thanks for the info guys. Chauncey I didn't even think about the barrel! Great! Does anyone have one? I guess I need to post this in the wanted section.

Well, I don't really want to get rid of mine. It's mint, like the lens, and nestled in the beautiful fitted black lacquer box it came in:-) The lens is in a standard Ilex #5 Universal and has never quarreled about the shutter not saying "made for Kodak". I would imagine that most "made for Kodak" shutters have a lens in them already - those that weren't furnished in barrel.

Well, guys this was just a thought. One of the many projects that will have to take a back seat to the building of the 11x14. Although, when the 11x14 is done that commercial Ektar would be nice...... Carol is not that far from my manufacturing plant. Thanks for all of the info.

Jim,

for a shutter mount there is a spacer tube that you will need for the front cell. for barrel mount the 10"/4.5 is too small and the 12"/4.5 is too large. The 14"/6.3 is it's own size. You could look for a pre-war uncoated Eastman Ektar, same size, but it has a great look also, perfect for 'Hollywood' glamor lighting.

Good luck with the hunt.

Paul, I have a 10" 4.5 Anastigmat that I got for $10.00. Just haven't had the time to get it on a lens board yet. The lens is very clean. The rear element group is not perfect and I was thinking to just use it as a wide open portrait lens. I may just put it in some PVC pipe and see what it looks like. If I find a shutter at a later date then I can mount it.

I agree that the correct shutter is needed, I have the 14" Commercial Ektar in the original shutter and I can say the images have a glow that other lenses don't. Don't Mickey Mouse the thing get a proper shutter.

Andrew, thanks for the advice. I am a patient man. A lot on my plate with camera building and such. One will come up sometime in the future. Maybe even Artara will find one! Thanks.

No. 5 Ilex shutters show up on the auction site fairly regularly. As mentioned, though, you need the one with the aluminum spacer on the front. The spacer is thread locked on the shutter and will usually be there if it housed this lens. I would also keep an eye out for a damaged lens that has a usable shutter. SK Grimes could properly mount your cells but it would be expensive.

I think your best bet for getting a matching shutter is to find another 14" CE with junk glass and just perform a lens-ectomy. After a certain point, time becomes worth more than money.

After finding thread size and lens spacing figures for the Ilex #5, I had to go look more closely at my shutter again. Turns out it has TWO adapters for the 14 inch Ektar. The front adapter reduces the thread size 3 mm and extends the front surface 15 mm. This would be the most obvious - a tube sticking out of the front (mine comes off with the front element now which is, I guess, why I haven't really noticed it.) The rear adapter reduces the thread size 3mm and adds about 8 mm of extension, to bring the total to 50 mm. Thanks for pointing that out, Glenn.
