Just entering into the world of large format and was a little apprehensive when my lens didn’t seem to want to fit tightly on the lens board. I got a spanner wrench and with the help of your instructions I’m now good to go! Many thanks!
Thank you so much for that video. It is amazimg that so easy built lenses without any focussing mechanism, electronics or multi purpose things work so absolutely great. Large format allows you so much opportunities with just thinking about whats you do...
This is excellent! I've just ran into this issue that seems like I need to change a lens board on a newly purchased lens, and this makes it very easy to understand what to do. And let me grab the opportunity here to also mention that your manual videos on the Bronica S2 were also very useful for me when I bought my first medium format camera, and I just sat at the table with it in front of me not being sure what to do with it :D So thank you! And hey, just realised your videos also helped with my newly bought RB back then! Great things David! All the best to you!
@@DavidHancock I think I have made it! And also I think without this tutorial it would be a very high chance to destroy the lens right away. Thanks again for your very helpful material. All the best from Budapest!
After you get the ring finger tight, how about setting the shutter to widest aperture and then open the preview slide so if the spanner should slip, it won't hit the blades and damage them?
The retaining ring should neither contact any of the levers on the front of the shutter nor should it, even tightened way down, put enough pressure on the shutter to affect lever or shutter operation. If it does, there is something wrong with the way the shutter is mounted on the board.
I have a Crown Graphic Special with round corners on the lens board I see you have no round corners. Where can I get a 65mm f8 lens for my crown with a lens board?
eBay, KEH, Adorama, and B&H are your best bets. You will almost certainly needs to buy the board and lens separately. When you do, be sure that the lens board is the right size (these had multiple sizes for different Graphic film formats) and that the opening is the right dimension. Last time I needed those, a few years back, someone on eBay was selling new metal lens boards he was making.
Great info. I have a 8x10 Century Model 1.5 patented 1903. I would like some info concerning the lens board. My board is 5 x5 inches, the board mounts by use of a spring mechanism on the top where you push up and into it. Is the 5x5 board a standard size? Any info would be helpful as I'm just starting out with large format. Kodak acquired Century and this eventually became the Kodax Model 2 I think,
I'm not sure if that's a standard size or not. It doesn't sound familiar and cameras that old may or may not have boards of standard size today. Fortunately, it may be very easy to order a new board on eBay either from a seller already making them or one who is making boards for other cameras (just ask and many sellers will make custom parts if they can.)
The shutter glass? Do you mean the two lens cells on either side of the shutter? Ideally, those need to be paired. The manufacturers typically put the same serial number on both cells because they paired them optically at the factory. While you can purchase replacement cells used on Ebay, if you're lucky, odds are it will be faster and cheaper to simply buy a new lens.
I have never seen shims. I believe that the lens designs are created to account for the spacing in the shutter size that the lens cells are designed to fit.
Hi David! I just watched youre vid, it is what I was looking for... Do you know if I can switch lenses between an speed graphic and a Calumet Cambo? Thanks.
Thank you! And to answer your question ... maybe. So if your lens has any functions built into the lens board, like the Graflex 1000 shutter and lens I have sitting on my desk as I type this, then you'd need to find an adapter from the Graflex to Cambo. I assume they were made but I can't promise that. If you lens simply threads on and uses a simple metal or wood lens board (depending on the age of your Graflex) then all you need is an appropriate Cambo board. Lastly, if you're using a barrel lens and the Graflex's focal plane curtain as your shutter, then you will not be able to use the barrel lens on the Cambo without either making some kind of shutter for it or taking very long exposures and using the action of removing and replacing the lens cap as the shutter.
Great video! I'm very new to large format I actually bought one with no lens. I had a hard time finding a lens with copal 0 on its own, mostly it has a board included with different size from mine and I don't want to spend money on an adapter, could I transfer the lens to my lens board if I'm going to buy one with different lens board in it? Thanks
Very interesting video! Thanks for the publication, just what I was looking for, I wanted to ask you if you can give me links to buy that key to extract the retainer that is on the shutter in the back of the lens, thanks again, I have subscribed to your channel for the next video .
Thank you! For the spanner wrench, here is the exact one that I use: www.ebay.com/itm/Pro-DSLR-Lens-Spanner-Wrench-Opening-Tool-Camera-Repair-open-Tools-15-to-100mm/191464371479?
I just picked up a $20 wrench off eBay about seven years ago. It's not the best but it's decent. The pointed ends have bent a couple of times and I've had to reshape them, but the screwdriver end are great. I don't recall it having a brand name. It looks like Neewer sells the same model that I have for $13 now.
Have been wonder how to do this so glad that I found your video!
Thank you!
David, you produce instructional videos of enormous clarity and provide a tremendous public service. Thank you for all of them.
Thank you!

Thank you and fantastic! I love large format work and I think it's done more to improve my photography than any other technique I've tried.
Thank you so much for that video. It is amazimg that so easy built lenses without any focussing mechanism, electronics or multi purpose things work so absolutely great. Large format allows you so much opportunities with just thinking about whats you do...
Thank you and it does. I find LF work to be very creatively challenging and rewarding because of it.
Excited for my first large format camera to arrive in the mail!
Nice! What did you pick?
Gr8 vdo on changing lens, which I have 2 do. Thx 4 sharing on Utube.

Hi, thanks a lot for this tutorial!
A question though, where can I find this sort of double wrench to unscrew/screw the back ring?
@@arthurherbert3140 amzn.to/3YHoGT2 there you go. That's the same as mine. Just an FYI, that's an affiliate link.
@@DavidHancock Thanks alot ! :-)
Hey David, the clarity of your instructions are top notch. a very helpful reference video. I am grateful you put these together!
Thank you!

Excellent. Thank you!

Can you plese told me ....how i change my shutterglass......and can i purchase this glass online
The shutter glass? Do you mean the two lens cells on either side of the shutter? Ideally, those need to be paired.

While you can purchase replacement cells used on Ebay, if you're lucky, odds are it will be faster and cheaper to simply buy a new lens.
Very interesting, how are the rear and front elements distanced? Are there any shims to place for achieving the exact distance together?
I have never seen shims. I believe that the lens designs are created to account for the spacing in the shutter size that the lens cells are designed to fit.
@@DavidHancock Thank you

Thank you and yes. Lenses do not care what camera they're on, nor what lens board. As long as the hole is the right size, they're fine.

Can I ask which spanner wrench you used, please? The quality of some found on Amazon seems to be less than good, according to feedback.

The pointed ends have bent a couple of times and I've had to reshape them, but the screwdriver end are great. I don't recall it having a brand name.

I have two Fujinon lenses but the shutter just says Copal without a number?
The number is based on the diameter of the opening for the lens cells. Some Copals have it printed on them, others do not.
