G Claron Lens Coating

[douglas_benson]

I am interested in hearing from anyone having experience with Schneider G Claron lenses. My concern is that they are single, as opposed to multi, coated. Is this factor obvious, or even noticable, in your images? My specific interest is in the 270mm focal length. I shoot a mix of black and white film and Velvia.

Thank you.

I use G-Claron lenses (305 & 355) for field work with my 717 and 1220

inch cameras and the results are excellent, even in high-flare

situations. That said, they aren't as flare resistant as my Apo-Sironar

S, but I don't know whether that has to do with the coatings or other

complex design factors.---Carl

In most shooting conditions you won't be able to tell but little if

any difference between a multicoated and single coated lens.

Multicoating is most important with zoom lenses, which can have as

many as 13 to 16 elements, and each element creates flare at the

surface. For LF work, single coating is all you need unless you put

the sun in every picture.

I use a 305mm G Claron, for 4x5 (and with roll film backs) and

8x10. I've shot the same scene with both the G Claron and other

Schneider multicoated lenses, using 4x5 Velvia film, and can see

absolutely no difference whatsoever. Color saturation and contrast of

the transparencies look the same. Sharpness is excellent. I believe

too much is made of the fact that the G Clarons are single- vs.

multi-coated. Sergio.

The G-Claron was designed as a copy lens for use in graphics arts

applications. As such, it was expected that as part of its normal

working condition, it would be pointed at a back-lit copy board with

very high contrast artwork attached to it. Any flare would seriously

degrade the image under such conditions, so these lenses were

internally shaped and edge-blackened to eliminate reflections and

flare as much as possible. The anti-reflection coating is just the

icing on the cake.<br>There are only 8 air-glass surfaces in the lens

anyway, and as stated in a previous post, the difference between

multi-coating and single-coating in this case is minimal. If these

lenses would have benefited from multi-coating, then Joe Schneider's

would have applied it.

I use both Symmar 180s, 210S, & G-Glaron 270 and the only differences I have noticed arise when shooting in the studio with tungsten illumination. All lens are excellent with regard to flare, sharpness, etc. However, the G-Glaron has a decidedly cooler color balance than the Symmars, requiring at least 5-10cc more yellow to achieve the same balance.
