Darlot Lens Expert

[TheDeardorffGuy]

Who on the forum is the Darlot lens expert? Thanks

[goamules]

It depends on your definition of expert! Dates of manufacture - no one, History - I enjoy researching lenses, Use - I don't shoot many of them, Rare Types - .....

What do you want to know about which type?

Here's the Darlt Lens. About 5 inch long w/ hood about 7 inch FL. Marked? Darlot Paris with the D over A logo and Made in Paris. No other data at all. Who what when where why...
Can someone fill in the Ws?

If you check the side of the front doublet, there is often a Darlot signature along with a date.

Is it a petzval? Is the front a cemented doublet and the rear two separate pieces of glass? It looks like a projection petzval I had once - mine was marked BF&Co and Darlot Paris. Look at page 15 of this catalog Yours might be the 1-2.

No Waterhouse slot?
The later AD trademark at right angles?
No B.F & Co?
I think B. French had a monopoly of "loose" Darlot lenses. They do appear on the larger US camera makers products, though. Points to a Magic Lantern lens which was shipped to the ML maker. We mustn't forget that, even pre-e**y, there were secondary imports into the USA. Darlot kept a design that looks a lot like the pre-Waterhouse stop photographic Petzvals.

Ok.....Disassembled it.
Front cell has 2 lenses cemented together. Marked in Pencil: Darlot Paris 767R
Rear Cell 2 lenses air spaced. The Thicker one Marked Darlot Paris 767

Looks like a stretched out tessar. So what is it?

[Richard Rankin]

Sounds like a petzval to me. Cemented front doublet, 2 air spaced rear lenses.

Here's an old link about it:

No slot, short hood, likely was a projection lens. Still will work well though.
