Which 90mm Lens?

[Paul Ron]

i have the 5.6 lens and love it!

I've had great luck with my 90mm f/6.8 Rodenstock Grandagon-N (multi-coated) for both 4x5 and 5x7 formats. A nice compromise in that it is relatively compact yet still has decent brightness, which does help for focussing. Typically fairly reasonable price-wise also.

I bought my first wide angle a 92mm WA Dagor lens as my second lens, following a 180mm Symmar lens that came with the first 4x5 camera I purchased (this was in 1974). A 90mm is especially useful for landscape, architectural, and urban images. I also have a f/6.8 90mm Grandagon which is a great lens. It is my most often used lens for images of buildings. I used just these 2 lenses for many years - and still do use them. As mentioned above you do need to make images as much as possible!

Any of the common 90mm f/8 lenses should fit the Intrepid as far as being able to mount the lens is concerned. Bigger ones, like the f/5.6 versions may have a too-large rear element to make mounting the lens possible - I don't really know, since I haven't worked with the Intrepid, but that is the case with lots of wooden folding field cameras. You might have some issues with bellows compression when using extreme movements. It that is the case, then a recessed lens board will definitely help. All my 90mm and shorter lenses are on recessed boards.

Multi-coated is definitely a plus. I wouldn't worry so much about not having images of the glass itself if you're buying from a really reputable dealer like KEH. If not, get good pictures and a return possibility if the lens doesn't match the description.

FWIW, I think the f/5.6 90mm lenses are just too larger and heavy. Plus they need a rather larger filter. My 90mm lenses take 67mm filters, which is as large as I go (I like small and lightweight). Get a decent dark cloth and you won't have any problems focusing the f/8 lens.

Center filters are not really necessary if you plan on only working with black-and-white or even color negative film. The light fall-off (a characteristic of short-focal-length lenses; not a defect) is correctable when printing (or in post). If you plan on using color transparency film, a center filter will really be helpful. I've been photographing for 40+ years, black-and-white only now, and have never owned a center filter for my 90mm and shorter lenses. I do give extra exposure and burn in the center of the images when printing though if needed.

As for a lens kit: a 90mm and a 210mm are workhorse standard lenses in just about everyone's kit for good reason. Fill in the gap with a 135mm or a 150mm. My personal preference is for the 135mm, since you can crop the image to get the 150mm view, but not vice-versa. 150mm lenses, however, have bigger image circles than their shorter cousins, so choose according to need.

Have fun!

Thanks so much for your advice. A lot to go away and think about.

Looks like a Schneider 90mm f8 super angulon in a later Compur shutter (late 60's to early 80's). Get an image of the lens front element, the serial number will give a date of production range using this chart:
https://ground-glass.net/schneider-lenses-age/

Prime difference between f8, f6.8 -vs- f4.5, f5.6 wide angle view camera lenses of the Biogon style is image circle, not ability to focus.. Yes, larger full aperture can aid in focusing but it is NOT the prime consideration to decide which wide angle lens.. It is much more about image circle, typical 90mm f8 will have an image circle of 216mm -vs- typical f5.6 or f4.5 image circle of 236mm exception being the Schneider 90mm f5.6 super angulon XL with a whopping image circle of 259mm and this WA lens is BIG, the rear element will not fit into a good number of field folders. Later versions of the 90mm SAXL had a modification to allow fitment into cameras with small lens board and front standard openings.. The other exception is the 90mm f8 sw Nikkor which has an image circle of 235mm in a small sized package.

Regardless, the camera (Intrepid) will be the limiting factor on lens performance via camera movement. 90mm lens means compressing the camera/bellows closer to the rear standard which greatly restricts camera movement ability. Solution to this is to use a bag bellows.

Check to see if the Intrepid's front lens board and front standard opening can fit the rear element of the lens of choice before deciding on any lens.. Which brings up the topic of "range of lenses"... camera's ability to properly support a given lens is dependent on the ability of the camera to compress it's distance between front to rear standards and ability to extend the distance between front to rear standards, remain rigid, stable, flexi free and allow minimal restriction of camera movement swing, tilt, shift, rise-fall for both front and rear camera standards.. Unlike lens fixed to the box cameras be they digital or film, view camera lenses are not designed/made with a fixed back focus distance. This demands the camera have the ability to do what the lens focal length demands..

Partial list of modern view camera lenses:

Keep this in mind for any lens choice. The better way would have been to decide on image goals first, lenses needed to achieve these goals followed by camera that best fits these goals.

As for multicoating -vs- singe coating.. it makes less difference than believed due to the fact view camera lenses tend to be simpler with fewer lens elements than lenses made for digital or roll film cameras. This mean fewer air to glass surfaces to cause internal flare and reduction of light transmission. This is why a uncoated Dagor made circa 1900's produces excellent image contrast due to the limited number of air to glass surfaces. Improvement in flare/contrast is improved by simply casting a shadow on the lens front element using the film holder's dark slide or similar.. Better would be a compendium lens shade. The only image making situation where the most modern multi coatings might make a visual difference is in very extreme back lighting situations which is very specific and not a common way to use any lens..

~Condition of the shutter is one of the greater concerns as many of these shutters are decades young, cycled many, many, many thousands of cycles and often in need of proper care ala Clean-Lube-Adjust.. Vast film burning grief can be caused by a ill feeling shutter in need of proper care.

Do keep in mind, there were no "hobbyist" view camera lenses made by the big four, Schneider, Fujinon, Rodenstock, Nikkor. They designed and produced view camera lenses for folks back then using these lenses to put a roof over their studio, food on their table and keeping the bill collectors from busting down the front door..

There will be a tripod involved, don't skimp on this as the tripod and tripod head is often as or more important than the camera outfit. Tripod stability, vibration control, ability to easily adjust then hold settings and be durable-reliable over the passage of images made are the prime tripod considerations.


IMO, at this point better to make images with that 210mm lens instead of searching for another lens, what is most needed at the beginning of the LF view camera journey is practice, practice, practice burning a whole pile-O-sheet film. As for film exposure apertures, yes, modern view camera lenses are optimized for f22.. This does not and should not mean chronic film exposures at f22 or when in doubt of what is in perceived focus closing the lens down to the smallest aperture on the lens aperture scale.. as image quality will and absolutely does degrade post f45 due to diffraction and this is an unescapable way of Nature..
The cure for this is to apply camera movements as and when needed to improve what is perceived to be in focus. Know all lenses have a single point or plane of actual focus, making the lens aperture smaller improves what is perceived to be in focus.. This previously posted guide on camera movements is a worthy read.

Thankyou for taking the time to advise me so comprehensively on Large format lenses and with specific reference to the intrepid. I thing your closing paragraph where you advise going out and shooting with my current 210 lens and becoming more familiar with the format makes great sense. I think I will put the 90mm idea on the back burner for now. Thanks again

i have the 5.6 lens and love it!

Thats nice to know. Thanks

Wise advice. When you do come back to get a 90mm I would suggest the Nikkor 90mm f8, it is multicoated, there are usually quite a few for sale from Japan, and it uses a 67mm filter which is a pretty standard size. For my take on a lens set for 4x5 you can read this: https://www.angusparkerphoto.com/blo...x5-view-camera

I was thinking the more I invest the more I will make time get out and start really using the camera

Would strongly advise against going overboard with lenses and other equipment during this phase of your journey. Maybe add that 90, and perhaps either a 135 or 150 to your existing 210 - live with this (three lens) combo for awhile...and who knows, this might just be plenty for the long haul!
