DALLMEYER Rapid Rectilinear 18x16 Ultra Large Format early brass lens 1868

An antique British lens engraved. DALLMEYER London 18x16 Rapid Rectilinear Patent N°15122. This huge brass lens was made in 1868 by Dallmeyer. It's a Rapid Rectilinear optical design with two symmetrical achromats on front and rear. This lens covers 16x18in, but you could use only one optical group to increase focale length and covering X2!!

Very few of these huge lenses were built in these long focale lengths, and as "Dallmeyer Rapid Rectilinear" patent was introduced in 1866, this 18x16in made in 1868 was one of the first! It's a rigid barrel with waterhouse slot (without waterstop). Brass barrel wears a lot of marks and varnish loss. But there is not major dent. Front achromat has a small chip on glass (see attached picture with red arrow). Rear achromat is in very nice condition.

Original mounting flange and lens hood are included. Diameter at mounting thread: 98mm. External diameter of flange: 136mm.

Maybe one of the last big Dallmeyer RR you could find, for pleasure of collectors and ULF wet plate enthusiasts. Check my other vintage lenses for sale.
