Interpreting your request sounds like you are looking for very high resolution performers for your extreme enlargements. If so, my experience with the following 8x10 coverage lenses may be helpful to...

Lee,

I do not have or use a website for photos and as you can see, there are many members with superb work like Mr. Gandolfi and Mr. Galli who handily add to the allure of the Cooke.

To answer...

Lee,

Here's my 15" Cooke IIE 8x10 fitted to the Sinar p2. It dominates the p2 front standard and I designed a reinforced mount/adapter system to add rigidity that is actually necessary. Without...

It kinda depends on which version of the G-Claron you got.

The older Dagor-layout, generally with serial number between 10 000 000 and 12 000 000, were stunning lenses based not only on its...

The short answer is no, since the LD Artar was not intended for use with a Copal shutter.

The long answer and my advice is to put a large shutter behind an unmodified LD Artar, and to never "mount...

My experience with Copal 3, Coimpur 3 and Compur 3 Electronic is that they are not "plug-compatible". The Copal 3 has more generous (meaning deeper and slightly wider) lens cavities for cells to fit...

First on whether your 2 plasmats in hand are symmetrical. Without looking at the drawings and reading the radii, it is hard to tell if these are symmetrical, be they GC or Hexanon. The GC Dagors were...

Bryan,

The optical layout of a plasmat does not dictate whether it is symmetrical or asymmetrical. It can be either.

In practice most plasmats are implemented as asymmetrical to meet the...

Bryan,

in terms of resolution and linear distortion, my experience is the perfectly symmetrical dialyte layout has proven superior to the asymmetrical plasmat layout - both in taking and enlarging...

Bryan,

My heartiest recommendation for your 8x10 enlarger would be a Red Dot or a Low Distortion Artar. I have stopped using Rodagons, Ronars and Componons in favor of Artar on my DeVere 5108. And...

Well, Schneider probably would tell you Repro-Clarons are probably "better" lenses than the G-Claron because they have use rare earth glass in their construction.

However, they "glow in the dark",...

Always up for a challenge, I tackled this a few years back and came up with a pretty neat setup, sent it to Adam at SK Grimes and when it came back, I was very pleased with the outcome. This system...

If you have determined your bellows are actually leather, this is your lucky day.

The magic stuff for leather bellows is known as "Horween Venetian Shoe Cream". This has been made for by the same...

Brian,

The 8x10 format diagonal is 325mm. To cover 325mm with a 210mm requires a lens with 76° degree coverage - without movements. If you need 25% movement in all directions, you now have an...

Series VIIa and Series V Protars are completely different lenses. Individual Series VIIa cells do not combine with cells from any series, or other lenses. Series V lenses were not designed to be...

Actually, these were made for use with film and glass plates, hence the pressure plate. This accommodation for plates also made the holders thicker. The later Linhof "Super Sheet Film Holders" that...

A picture is worth a thousand words...enjoy!

It's amazing what it inspires me to do. Here's what my Saber sometimes wears when the Phase One isn't otherwise occupied....

Buy a Chamonix Saber - 1/2 the weight and 1/3 the bulk. If you want another lens, get a second Saber. One of the most pleasurable 4x5 cameras to use handheld.

You have to think through 2 issues - holding the weight as well as managing the vast shift in weight distribution inherent in using anything bigger than an 8x10.

As such, you may have to rethink...

Brian,

Many 1960's German large format lenses had "integrated" Synchro-Compur shutters that are not just spin-on and spin-off. In fact, I am sure that was a selling point to justify the much...

If you need access to the shutter, I don't see how there is any other way to do it without the disassembly as described. Take a close look at your lens and perhaps it is different but I doubt it....

Luigi,

The short answer:

Depends on what you call "easily transferred".

The long answer:

Since this question has been asked by a few on this an other forums, it deserves a long - and...

Tim,

An admirable quest - one that has been successfully satisfied by the late Steve Grimes and now in the hands of the capable young men at SK Grimes the company in Woonsocket, RI.

The idea is...

The most significant effect of incorrect cell spacing is that the distance of the iris to the optical system has changed, however minutely. The optical system renders this deviation as losing some of...

So great minds think alike!

I did the exact same thing after getting my Rodenstock Digital lenses, the generation just before the current Digaron's. They are really "perfect" as perfect gets,...

Sounds like we have identical setup's and experiences!

From my testing, there were two consistently good performers in both digital and film domains even though there were definitely designed...

If you have a way of attaching a DSLR or better still a MFDB to your p2, then you can really put the lenses to the test. LCA did not show up as glaring problems until I set up my p2, attached my...

Here's an example how useful the Sinar Shutter can be if you decide to go with it.

One of mine is used with a Deardorff V8 in combination with an iris flange using custom-made adapters. This...

Hi hiend61,

I have two Sinar DB Shutters. Both have worked daily and flawlessly since new. They are very useful and if you find one that is New Old Stock (NOS) or unused with all the needed...

Hugo,

Thanks for your input and great reference. You must have one of the rarest Protar V's in existence! Bravo!

The difference in performance with contact prints between your Protar V and the...

Thanks, Sandy, for debunking the myth of the Protar V from actual ownership and usage experience. In your mind, what may be possible alternatives in both quantitative and qualitative terms to the 550...

The reason I posed the question is not in defiance of what 100 years of optical engineering may possibly bring us, as in the case of a quantitative comparision between the 550 XXL and any 100-year...

In mammoth land, has anyone compared the 550 XXL against a Protar V of similar focal length in actual performance? It seems that in the Protar V lineup there was a 460 with 840mm of coverage and a...

I went through this comparison about 20 years ago and bought a Linhof Technikardan 617 with the 90 Super Angulon and a Center Filter. Took it on a number of trips to Europe and did a few assignments....

Oren,

What do you reach for over the G-Claron's to get the effect you were describing above?

carver

Tim,

It all follows the law of physics - mass, center of gravity and distribution etc. 4x5 cameras are dimensionally smaller and their bellows extension significantly shorter so it is conceivable...

Tim,

1/15 second would not produce results that the majority of semi-skeptics can embrace as having eliminated all possibilities of movement. And honestly, nor would I. I have plenty of lens...

Tim,

I agree with Paul wholeheartedly about high-quality prints. It is the final arbiter.

The only thing about printmaking now is that many professional printers scan and print which injects...

Tim,

OK - I would have thought that strobes might have been easier for you but I should not have assumed so - sorry! In any case, for as long as you can use a shutter speed at close to the...
