CALTAR II-N 300MM (f/5.6, 7 aperture blades)
What do you guys think of this lens, the CALTAR II-N 300MM (f/5.6, 7 aperture blades)? Is it the same as the Caltar listed on the old lens section of this site:
Calumet Caltar II
E/G: 6/4
F: 300 mm
Maximum Aperture: f/5.6
Cover Circle: 425 mm
Price: $900
YR: 2
If so, I might be interested. Seems to have a large coverage circle (more than 2x 4x5's 163 mm diagonal), and it's relatively large maximum aperture.
Re: CALTAR II-N 300MM (f/5.6, 7 aperture blades)
Caltar II-N lenses are re-badged Rodenstock Sironar N lenses that are still being sold by Calumet Photo. They pre-date the Rodenstock Apo Sironar N series. However, I have heard that there is no significant difference between the Sironar N and the Apo Sironar N. Rodenstock added the "Apo" designation for marketing purposes.
Be aware that the 300 f5.6 is a large, heavy weight lens, mounted in a Copal 3 shutter.

There are many equivalent lenses available used for much less:

Bear in mind this is an 8x10 lens, and as Gem said is heavy.
Re: CALTAR II-N 300MM (f/5.6, 7 aperture blades)
I have a Sironar N 300mm f/5.6 MC for 8x10 work. As Gem mentioned, it was also sold as a Caltar N lens. It's a very good workhorse normal lens for 8x10 work, but it's a heavy Plasmat design in a large Copal 3 shutter. I'd consider it very mismatched for a light 4x5 field camera. The image circle is overkill for 4x5 unless you're doing heavy architecture or table top shots. The speed is nice, but it's not difficult using slower lenses as long as they're normal or longer than normal for the format. I love a 240mm on 4x5, so a Fujinon A 240mm f/9 might be a better choice. If you're set on a 300, the Nikon 300mm M f/9 is excellent. Both are top quality small lenses with lots of coverage for 4x5.
Re: CALTAR II-N 300MM (f/5.6, 7 aperture blades)
A few clarifications...I'll be using it with a Linhof Super Color Symmar monorail, not a box-type field camera.
This lens is on eBay now right a current bid of $36, as there is an issue with the shutter timing at slow speeds that needs to be fixed.
The reason I'm getting into LF is because I am interested in the movements, both to correct perspective and more importantly to engage in selective focus; because I want the capability of very shallow depth of field; and because I want to have image quality better than medium-format digital backs without paying insane prices.
I often use a 58mm:f/1.2 lens on my four-thirds system, and would even be interested in an f/0.6 lens for my E3 (my 58/1.2 lens was intended for a Minolta 35mm film body...and the dof of it on a minolta body would be equivalent to that of a f/0.6 on my 4/3rds format E3). f/0.6 corresponds to f/4.5 on 4x5 large format. But the f/4.5 lenses that I've seen seem to have smaller image circles.
Re: CALTAR II-N 300MM (f/5.6, 7 aperture blades)
Believe me, the depth of field with any 240mm or 300mm lens is shallow, so I wouldn't worry about the difference between f/5.6 and f/9. LF is a world away from "four-thirds" , so don't get hung up on the need for a fat aperture on any long LF lens. The Fujinon and the Nikon have image circles over 300mm--very large for 4x5. However, if you can get a good deal on the Caltar/Sironar, your camera will handle it fine, focusing will be a breeze, and you'll be ready to move up to 8x10.

Symmar is the lens not the camera.

The link that you furnished shows a Linhof Kardon Super Color 4X5 monorail camera, which includes a Schneider Symmar f5.6 150-f12 265 convertible lens. If that's the camera you are planning on purchasing, it's a nice outfit, worth the price. The lens is a great performer.
If you showed the picture of the Linhof merely to explain which camera you will be using, I can tell you from experience, a three pound f5.6 300mm lens in a Copal 3 shutter puts a strain on the front standard of any 4X5 camera, even a Linhof. Especially when it is extended out for close-up photography.
If you insist on using a 300mm lens, look for a Fujinon 300C or a Nikon 300M. more expensive, but smaller, lighter, and mounted in Copal 1 shutters. Excellent lenses to use for selective focus. They have large image circles for perspective control on 4X5.
By "four-thirds". do you mean 35mm? 4X5 is a different ratio than 35mm.

No problem. This front standard easily can handle a 300 5.6. It is the same front standard that was used on the 5x7 and some of the Linhof 8x10 Kardan cameras.

The poster is referring to the Four Thirds digital sensor format, 13 x 17.3 mm.
