Newbie question: lenses
Hi. I'm brand new to LF, and just bought my first camera and lens. I have a
question about the lens, a Schneider Angulon 90mm f/6.8. I know it's old; the serial number is is mid 5 million, making it a two years my senior. The trouble is, I can't seem to find any information about it on the web. What I did find conflicted with everything else. I'm looking for just the angle of coverage and coverage at infinity focus. It was mere curiosity before; now that I have it in my hands, I'm concerned. I have loupes with more glass than this lens has; it's not at all what I was expecting. Is this reasonable for a 4x5 wide angle lens? Will I get reasonable coverage and movement on 4x5? The camera hasn't arrived yet, so I'll have to wait a few more days to find out. In the meantime, you can help drive me crazy with more rumors and suppositions. What can you tell me about this lens I bought? Thanks. Mike. |

Ah, someone else like me who buys first and asks questions later. : - )
I believe this lens has an image circle of 154mm and an 81 degree angle of coverage (these numbers are taken from a secondary source, not from Schneider, so it's possible they're off a little). Since 161mm is about the size of the image circle required to cover 4x5 you won't get any movement to speak of with this lens. It just barely covers 4x5 when stopped down. However, many people happily use this lens for landscape work since movements often aren't necessary with that kind of work and its small size makes it ideal for backpacking. If you do architecture, product photography, or anything else that requires movements you probably should return the lens or buy a second one with room for more movements..

What I Schneider is one company that provides a lot of info on the web. Others IMHO could learn from Schneider. http://www.schneideroptics.com/info/.../6,8-90mm.html Nick |

As you know this is an older lens and IMHO not a very good one.It has an image circle of 154mm at f16. In reality it may be slightly more but not much. The image at the edges of the image circle is also not very sharp and there is not much you can do about this problem.The Super Angulon is a newer and much better version of the same lens. If you are going to be buying used lenses you might want to go back through issues of View Camera magazine. Over the years we've run articles on most of the lenses you will find out there. If you are moving up and want to find lenses that are the equivilent focal lengths to what you may have used in smaller formats there is a lens chart on our web site in the Free Articles section. www.viewcamera.com Go to the Free Articles section in the black menu bar. There are several articles that might be helpful to you. steve simmons |

I might suggest getting one of these books as they might be helpful as you dive into large format User's Guide to the View Camera by Jim Stone Large Format nature Photography by Jack Dykinga Using The View Camera that I wrote a few years ago. All should be available from Amazon.com There is another book that some people suggest called View Camera Technique. As a reference this is very good. As a starter book it is a tome. steve simmons |

I believe this lens has an image circle of 154mm and an 81 degree angle of
coverage (these numbers are taken from a secondary source, not from Schneider, so it's possible they're off a little). Any thought of identifying your secondary source? It might be helpful to the questioner and to others who might have the same question if they new of a place to go look for this type of info. steve simmons |

Look at http://www.hevanet.com/cperez/results.html and see the variations in results from different samples. This is true of most lenses especially older ones. I would never buy a used lens (or new?) without some sort of "return if it's a dud" warranty. I'd consider the small size of the lens, whether you need movements and finally testing the sample you are send and decide if it might be useful. A SA has more coverage but is a MUCH larger and heavier lens. -- Stacey |

.com... Ah, someone else like me who buys first and asks questions later. : - ) I'd been lurking here for about a month now, and noted the relatively low message volume. I absolutely didn't expect this gushing forth of on-topic information. Wow. :-) Thanks, guys. All of it was useful. |
