Advice on 150mm 4x5 lens I have Been Offered

[IanBarber]

My current lens is a Rodenstock Sironar - N MC f/5.6


Then lens I have been offered

SINAR SINARON S F5.6 150MM


My reason for wanting to change.

I bought the Rodenstock Sironar - N when I first got into LF.

The lens appears to work fine but appears to be soft around the edges. Now this could just be the quality of the scan from the Epson V800. I do seem to use Rise and Fall quite a bit on my Chamonix 045N-2 but from whatt I can gather, I am not loosing any image circle because even at maximum rise, I can still see all 4 corners of the ground glass when looking through the front of the lens.

Can anyone advise as to whether the SINAR SINARON S F5.6 150MM would be a better lens. The seller is asking about $355 (£280) for it

There's an old discussion here:

http://www.apug.org/forum/index.php?...-lenses.16395/

Which may or may not be helpful. What aperture are you using your current lens at? There are lots of options in that focal length, so don't be too hasty with a purchase. I'm sure lots of people will give you advice here...I'm happy with an uncoated 15cm Tessar! I'm not chasing optimum sharpness though, others will be far better qualified than me to offer advice.

The Sinaron S is the exact same lens as the Apo Sironar N. if you want to improve you need the Apo Sironar S. The Sironar N MC was relabeled the Apo Sironar N when the Apo Sironar S series was introduced. The Apo Sironar was renamed the Apo Sironar W at the same time.

Gosh... they dont make it easy do they.

If I have read you right, you are saying that the lens been offered is probably no better than the one I already have apart from its appearance ?

You've already got a superb lens, stick with it. I've had my 150mm Sironar N for about 30 years and wouldn't think of changing it. Bob's saying it's a rebadged version of the same lens.

I don't know what apertures you're using LF lenses are optimised for f22 and that't affect edge/corner sharpness.

Always blame your photographic shortcomings on the equipment !!

Yes, it is a rebadged version of the Apo Sironar N but it is also an older one. So they newer ones might be a better performer, marginally.

I think the key word here is "marginally".

The Rodenstock Sironar - N MC f/5.6 is the rebadged or the SINAR SINARON S F5.6 150MM is the rebadged
