A long time ago, I began collecting "MC" (this goes way back) reduction lensboards that take a smaller, circular, "bayonet" mounted board. They made reduction adapters for many cameras, including a...

There were many kinds of reduction adapters for Cambo, of which Linhof Technika was one. Moreover, many cameras brands made Technika reduction adapters for their camera.

With the smaller sized...

Driving by a trailer lot, I caught a glimpse of a pop-up trailer like the one shown. I stopped to get a closer look, and that was it. When my little Metro gave up the ghost a couple of years later,...

This is really interesting. I've used my timer for at least a couple of decades or more, and I didn't realize that these adjustments were available. (Yippeee! :D)

It looks like the two...

Richard, What are the pods that you refer to? Thx.

This is a reasonable query.

I think that there will always be moderators; they've always stepped forward, and they've always been dedicated to the task. This says a lot about our LF community. ...

I think that it's important to treat framing independently from perspective, the latter being camera position. In approaching a composition, I like to explore different camera positions without ...

I purchased a 24" BenQ last year that currently sells for $399 from B&H, and I think that it's an excellent monitor. I have the X-Rite I1 Display Pro Colorimeter that works well with the BenQ...

HP-5 . . .

Long live Ilford.

I enjoy photographing architecture, and I finally came to the conclusion that the "progression" from 90mm to my 121mm Schneider Super Angulon was too much of a jump. My solution was to purchase a...

I have two of these, one for 8x10 and a second for "4x5". They're well made.

The 4x5 version works fine for my 6x9 view camera and works well enough on a Sinar F. As to the latter, it fits fine...

Something else worth mentioning that Kerry Thalmann observed in his comments on the topic. . . The Nikon 90mm f8 lens has eight elements, whereas other 90mm f8 or f6.7 SW's have six elements.

Good point. To be considered, but not an end-all, be-all. I've sold lenses because of their high contrast.

That said, I gathered that high contrast was an important consideration for Ansel Adams,...

I think this makes a difference when making focal length comparisons between different formats. But for me, it wouldn't make a difference when deciding on lens progressions.

Well, I'm back, and I thought about it. :)

For me, the multiplicative approach (above) works best. Every time I've increased the focal length by 1/3rd, I've "shaved" off close to 12.5% on each...

I use HP5+ with D76, and I seem to do OK with expansions that I use. But, there might well be a better combination.

As a comment, if one's extending contrast by increasing development time,...

Just a comment . . .

I used to have the 171mm front format frame on my Arca, and I liked the "wide angle" pleated, leather bellows, because they could handle wide angle optics, yet extend far...

What was his name?

In the old days before PayPal, I would only take a check for an item I was selling, if it was allowed to clear prior to shipping. Ditto any other type of payment: cashiers check, money order,...

I'm thinking that price depends on the following: Capability, Rarity, and Reputation/Perception.

Under capability comes, image circle, maximum aperture, focal length, and shutter. Generally...

Versus a zoom 24-70mm lens, all be it "macro", I would think that a 35mm, fixed focal length, macro lens would be preferable for DSLR scanning. A zoom lens is prone to chromatic aberration and...

What's a good source for an 8x10 ground glass. (It's for an 8x10 Burke and James.) Thx.

I think that this is more about the "design" of a Linhof Technika, versus whether or not the OP picked the "right" lensboard. The fact is, focusing a lens this short on a Linhof Technika is a pain...

My favorite definition . . .

"If it works, it's art."

:)

Welcome to the forum.

Although a wee bit on the heavy side, you have a very good camera system. If you don't already have one, you'll need a bag bellows . . . especially for architectural...

For the 90mm focal length, there's a pretty clear response . . . A 90mm Nikon f8 lens would be excellent. I have one of these. I photograph both landscape and exterior architecture, and this lens...

It's 50% more surface area on the negative. That's quite a bit.

I've considered going to 5x6.25, which is the largest 4x5 ratio one can pull from a 5x7 negative. But, I print small, so why...

Many excellent points made. I especially like Rod's comments on how contact printing can expand the number of stops that display detail, and his observation that, in viewing the ground glass, it's...

Multiple 8x10's I've had (and have) have been (are) prone to internal reflections. That was true with a 2D that I had, a Sinar, and now with my Oschwald era Arca Swiss.

I use a Lee compendium...

With what camera?

I'll soon be selling my Sinar outfit that I've enjoyed customizing and using. That will leave me with the only camera that I really need, an Arca Swiss kit that I've assembled over the years.

My wife and I are retired. While age makes us vulnerable to COVID, our retirement status and income has enabled us to STAY HOME! As a result, it's been a relatively productive year, both in...

Top to bottom using my calipers: 93.7mm.

But more likely, 93.5mm, given a dimension given in the green table for 300mm Rodagon-G lenses.

So even then, a -G wasn't necessary. Interesting.

I'm still wondering if there are uses for a lens like this in today's world? But, maybe not.

For a number of reasons, large format RF just does not make sense to me. Medium format RF can make sense, but not large format.

Woe, talk about days past.

Sounds like I have a relic. :)

(Wait a minute, I'm a relic.)

Thanks Bob for your reply.

How would a lens like this be used for billboards? Based on size, it makes sense. But, what would be the (simplified) process that makes use of a lens like this? Is...

Thanks for the graphs. Wow indeed!

It's funny . . . I print small and typically don't print larger than on 8x10 paper. (Maybe I'll start printing 80x100's.:) Trouble is, my darkroom is...
