A bit of fun, hopefully also with a purpose. When I started off in LF I just had 'normal', in-shutter lenses, a Fujinon 125mm, the diminuitive Ektar 203mm, a couple of Nikons... you get the picture.

Then I bought a secondhand Linhof monorail and it came with a 480mm APO-Ronar in barrel. 'Wow! What a weight!' I thought. Having read a lot more on these pages I realise now that there are a lot of big, heavy (and often old) chunks of metal and glass out there.

So show us your whoppers!

In shutter or barrel. In a similar fashion to the Cooke serial number thread (and others) I will use a public Google Sheet to record the results, and sort them by weight as it is updated.

It could be helpful to know if a lens will fit on a particular lens board / camera system, so if you can please also give the mount hole size and the distance the lens projects backwards from the mount. (The small print: Readers should assume that all of measurements of weight and size are approximate and they should satisfy themselves that a particular lens will fit on a particular camera).

Weights and dimensions can be given in metric (g, kg, mm, cm) or imperial (pounds, ounces, or decimal pounds :-), I will have columns for both in the spreadsheet and will convert the entries as required. Weighing attached to a lensboard is okay, the additional weight should be negligable for anything with some heft to it.

Preferably no real oddities like lens from lighthouses etc (although it might be fun to categorise anything odd separately :-) Only lenses which are (or have been) in your possession. Apocryphal or otherwise interesting stories or images are most welcome but won't make it into the spreadsheet.

Okay, my tiddly little entries to kick off...

182896
Cooke Series II 10.5" f4.5
2.56 lbs (1.164 kg) on Sinar top hat board
2.75" (70 mm) flange hole
0.50" (12 mm) projection backwards

182894
Wollensak Velostigmat II 12" f4.5
2.95 lbs (1.341 kg) on Sinar top hat board
3.25" (82 mm) L section flange
0.75" (18mm) projection backwards

182895
Rodenstck APO-Ronar L 480mm f9
3.89 lbs (1.768 kg) on what was a Sinar funny aperture thingee board
2.83" (72 mm) mount hole
0.55" (14mm) projection backwards


The Google sheet which will record the results is here (https://docs.google.com/spreadsheets/d/1B-TCAOuU_FjImighXrrT6Yb2xtvF4cX6yQOXO3tbtTs/edit?usp=sharing).

I don't have the specs anymore, but my heaviest, so far, were a 200/2 S.F.O.M. that weighed ~ 7 kg and a 36"/Bell & Howell Telephoto that weighed ~ 20 pounds.

My 900/10 Apo-Saphir is a relative dwarf at 4.1 kg. A 600/9 Klimsch Apo-Ronar mounted in brass and sold long ago weighed only 3.3 kg. A 6"/1.9 Dallmeyer Super Six, also sold long ago, weighed only 3.3 pounds.

Here's a link to a site that shows many quite large lenses: http://alag3.mfa.kfki.hu/astro/giantlenses/index.htm

Peter, if you're trying to compile information that will help prospective users determine whether a given lens will fit on their cameras, maximum diameter of the rear cell, for those lenses that have one, is also a critical specification.

For example, the rear cell of the 210mm Super-Angulon (at least the late-production version - don't have data on the earlier ones handy at the moment) flares to 125mm.

A bit of fun....................].

Perhaps this has some entertainment value in the Lounge section, but the call for listing seems a bit unclear.
We do have a number of these type of "Guiness Record Book entry" threads already. I maintain a couple of "historical/serial number" threads supported by others who provide information - of some use for a small minority. But I can't see any usefulness in your suggestion.

Dan - many thanks for the info (now added), and for the link to the 'giantlenses' website. Incredible! Presumably some of these will be one-offs so would they have been hand-made? Makes me think of the aproned men at the Dallmeyer archives (http://www.thedallmeyerarchive.com/Records/lantern_slides.html). Hard to conceive these days that lenses were once made by hand.

Oren - a very good point, the assembled lens still has to go through the opening provided for the lens board! Appropriate columns now added to the spreadsheet. Folks - if the rear cell is larger than the mount hole then please give this dimension as well.

Steven - when I saw you had replied I thought you might have supplied some special data on esoteric lenses... Oh well, it's obviously not your cup of tea. Or maybe you thought I was comparing this thread with the various (and very useful) serial number / historical threads in this section of the site? Not at all, the only similarity is that I am collating the responses to a publically accessible spreadsheet. Thanks for commenting anyway - although if can bring yourself to impart any information on historic lenses that would be great, and, I'm sure, of use to beginners like me. I have no idea how big and heavy the various models of Dallmeyers, Cookes, specialist soft focus, or even Suters, Lerebours etc. are :)

The hand-made puts sample variations into human experience. Thanks for the link, Peter.

The physically largest I own is here. It is not heavy. Most of the weight is the glass. The brass is lightweight. It is a #7 Voightlander Euryscop (http://www.digoliardi.net/voigtlander7/voigtlander_7_i/engraving_2.jpg). I am not particularly impressed by its performance which was admirable in its time to produce sharp images, which it did, but enthusiasts pursuing soft focus, swirly OOF will likely be disappointed.

182910

Very Best,
Jac

Aside: I did not have the brass machine polished. I found the lens among estate goods waxed, wrapped in linen as if it had never been used. Being stupid, I passed on a beaten Petzval in the same lot.

Also special thanks to Steven Tribe who put me on the path to understand this lens several years ago.

I am currently trying to fit large lenses to a 5x7 Gundlach Korona. (I'll write more about that later.) For me, the most important measurement has been flange diameter. I'v just purchased a voigtlander Petzval with a 5.5 in. flange that I need to figure out how to get it onto a 4.5 x 4.5 lens board. Second figure of importance is diameter of a lens, to see if it will fit through the front standard as I don't want to try haning a really heavy lens on the Korona's front standard (would like lens to straddle it.) Third measurement would be focal length, of course. I have about 39 inches of rail.

Kent, I use cup-shaped adapters to mount fat lenses to small boards. An alternative is a 2- or, more likely, 3-piece board. Three pieces, with the middle piece somewhat smaller than the one that attaches to the camera so that there's room for the sliders.

About heavy lenses, I hang heavy lenses completely in front of the board, use a crutch to support them. On my Cambo, the crutch is a mutilated front standard. An inexpensive lab jack would have done as well and cost less.

Thanks. Not yet! I only got it recently and most of my free (photography) time lately has been taken up with making various adapters, and adapting lensboards. Will let you know when I have.

Well, they say size doesn't matter but that is mighty impressive :) Shame it has no magical qualities.

They do say (in smaller formats anyway) that a really worn lens can be a good sign.

My current LF cameras are a Canham 5x7 and a Sinar P2. The latter gets little use, but it put me on the path of Sinar compatability / adaptability for larger barrel lenses. I decided to make a step-up adapter (Canham to Sinar), sacrificing a lensboard from each camera and bolting them together with a square of ply (18mm/0.75") between (obviously with a large circular aperture cut out).

Now I can mount a Sinar shutter, a somewhat stripped down Sinar 'universal' standard, and lenses on Sinar boards. The Canham copes with the weight remarkably well (all hung 'off the front') and is rock solid. And the entire rig is far, far lighter than the P2. Can take some shots to illustrate if you want.

The Canham has thin plastic (nylon?) washers between the metal surfaces, maybe this helps with 'bite' to keep the surfaces from slipping against each other? You could try adding the same to your Korona.

Heavy lens support.

This will not work for everyone. I like Dan's crutch support better. Well, here is a test bed I used once with a Sinar Alpina. The bed was designed as a camera support for a large telescope. One sold on the big auction site for $15.

Sinar P front standard handles lenses like this with ease and stability. Sinar shutter allows barrel lenses like to be used with equal ease.
Trade off, the entire outfit is HEAVY.

For novelty, have a 36" f8 Perkin Elmer aero recon lens in Fairchild K38 shutter and a 24" f2.5 Aero Ektar in the same Fairchild K38 shutter. These were purchased in the late 80's, for very little $. Very few wanted them back then. Images maybe later.

One of the lenses I have handy is my 16-18" Graf Variable. This lens come in at 5# 9 oz. It fits on a 6 inch lens board and projects back in about an inch and a half. The lens is 5 inches in diameter I use it on the studio camera and it has been out in the field once but it did strain the front standard of my walnut 8x10 that I built.

Steven Tribe
2-Oct-2018, 14:06
I too have the 16/18 Graf variable and it isn't the largest size. The largest is over 8lbs! The catelogue/guide to use in cameraeccentric unusually gives the weight for all sizes!
When talking about lens bulk and useability on camera types, it is important to bear in mind that the torque applied to the mounting point on the camera (Weight x the distance from th center of gravity to the mount) is generally more important that the actual measured weight..

So a long Petzval like Emil's will do more damage than an anastigmat design of the same weight!

Jody_S
2-Oct-2018, 15:06
I posted an image of 3 of my largest here, in '14. Still haven't mounted any on a camera, though I do now have an 8x10 studio camera that could hold any of these. The big one in the back is a modified Petzval design coated Sony 300mm f2 projection lens. The largest lens designed for a large format camera that I own and actually use is a 14-1/2" Verito. The largest lens full stop that I own is a Canon FD 800/5.6.

That's getting on for the Dallmeyer lens in the photo on this page (http://www.thedallmeyerarchive.com/Records/walkers/Walkers.html). A 'hundred weight' (cwt) was 112 lbs in the UK :eek:

A pdf'd article (linked on that page) from the Amateur Photographer magazine describes an experiment to see 'what stereoscopic effect was obtained by reason of the large glass diameter'.

I was intrigued by The Boston Camera though, and had a look at Wikipedia. They said it could photograph a golf ball from an altitude of 45,000 feet... Pah, that's nothing, I could do that. You wouldn't be able to see the golf ball but I could do it :)

Peter, if you're trying to compile information that will help prospective users determine whether a given lens will fit on their cameras, maximum diameter of the rear cell, for those lenses that have one, is also a critical specification . . .

Another consideration is whether a camera, even an 8x10, has the stamina to hold the lens.

My largest lens is a 610mm Repro Claron mounted in an Ilex #5 shutter. It stands 5" high, and the shutter is 5" in diameter. It weighs 3.14 lbs, which by comparison to some lenses, isn't that heavy. While I wouldn't call it compact, it has a filter size of only 82mm. Another advantage size-wise is that this lens weighs about as much on the front as the rear. So, it's balanced.

My Sinar Norma front standard can hold this lens just fine. Not so sure about a Sinar F, though?

The Zettor shutter has been rebuilt by Zacks Camera Repair and works very smoothly. It has 4 settings:O = Open, Z = like the classic B mode, M = "instant" = about 1/8 second depending on how the cable release plunger is pushed, C = closed. The Zettor has huge blades and needs a strong long-throw cable release with at least 25mm of travel. The first 24mm tensions a big driving spring and the release happens in the last 1mm.

The 132.9 F2 B&L Super Cinephor weighs 520 grams.

Thanks Daniel, added.



R. Knoll f5.5/360 Doppel-Rigonar. Not nearly as big as some but my largest lens. I recently finished machining the mounting flange and have it mounted to a 6x6 board.

Nice.



My daughter now off to college with the Dallmeyer 8D that I use for my 20 x 24 wetplate work

Wow. That certainly is a whopper :) I wonder what happened to the lens in this Dallmeyer 8D thread (http://www.largeformatphotography.info/forum/showthread.php?109210-Dallmeyer-8D-Portrait-Lens)?

I've been using this 305mm Metrogon since 2010 on my 8x20. It weighs 6# without the red/yellow graduated center filter(s). I haven't seen a 305mm offered for sale in many years. The 75mm and 150mm versions are pretty common. The 305 fits on a 6" lensboard. To accommodate the weight I incorporated a strut to support the aged components of the Kodak 2D I converted to 8x20. Waterhouse stops are the only way the apeture can be controlled. There is no room between the lens cells to fit anything in there. I use an 8x10 darkslide as a shutter. The product sheet has most of the info you were looking for. The small view camera lens (for size comparison) is a 135mm Schnieder on a 4x5 Wista lensboard.

Do you fit the darkslide between the center elements as possibly Waterhouse stop and sliding shutter?

There is enough room for Waterhouse stop between the cells.
The darkslide shutter goes over the front element. The attached photo shows an identical application with a different lens and 4x5 darkslide. I don't have a photo of my darkslide shutter on the Metrogon, but the design is the same as the photo but using an 8x10 darkslide.

There is the possibility of a shutter between Metrogon middle cells. I had one on 8x10. Sorry I don't have more pictures but here is one. It fit. One fixed aperture but that was to maintain optimal resolution at infinity, a rule for certifying mapping lenses during its time.

I have another of similar design, but more complicated for very high shutter speeds.

Very smart. Simple, ergonomic.
