That looks like an equatorial mount for a telescope.

Mike

Is that crank underneath the autofocus?

Bill,

I can't say I look at it nor could I - easily anyway. It's all by feel. But I think the most important thing is my left hand stays on the camera strap until the camera is secure and almost...

I just don't see the AS mount as a problem. Once you get used to it, it is very easy to drop the camera mount down into the bed and I just don't let go until I know it's secure. It only takes a...

I'm not 100% certain that Mamiya American repairs the Toyo's but they are the distributor and I'd consider it unlikely they do not.

Here's the page for their medium format repairs:

No offense but if you obtained better results with a Caltar 150 in the macro range than at longer distances and all of that at F64 then I'm not sure your testing is over <g>. A general purpose lens...

Also with due respect for Bob and for his active participation in these forums, tilting or swinging the back on axis or with base tilts will not move the film outside the cone of light. Rear rise...

You didn't mention whether artificial light is being used or daylight. If light levels are low, reciprocity characteristics come into play. Those adjustments for reciprocity differ between films. ...

Toyo made a 5x7 field some time ago. Occasionally, you will see one for sale. I'd venture to say I've seen them often enough that you could easily find a whole camera. Whether or not a back could...

I cannot speak from personal experience either and, perhaps, the previous poster and I have heard of the same workshop (Palm Beach Photographics in Delray Beach, FL put it on) but I know of a...

I used the less expensive LPL 4500 Dichroic for a number of years and was very happy with it. It is not really adjustable for alignment so if you buy used, make sure it's close to perfectly aligned...

I've just returned from a trip on which I used Readyloads exclusively. I made the decision to take them because I've had some trouble with getting boxes of film through security. While they are...

I can't say that I've had to do that repair (yet). But, here's what I would do if it became necessary. First, look at the website http://www.fargo-ent.com/index.html

They carry most camera...

A fresnel installed on the eye side of the ground glass won't affect your plane of focus.

On the lens side, it's a different story. Some compensation must be made.

Mike

I'm partial to the F64 backpack. It is very comfortable to wear, lightweight and has plenty of room. More, in fact, than you might need. It carries a Toyo, 3 lenses, meter, cloth and a polaroid...

Lesson one in Photography 101 should be, "If you find something you like and you can afford it, buy it". That should come before lens testing, what iffing and darn, it's $5 cheaper at xxx.

I'm...

Bob & Arca Swiss:

Thank you both for the information.

Mike

The Arca Swiss catalog is beautifully done but it confuses me a bit (possibly be cause of the large number of configurations available). I am trying to figure out a 6x9 configuration but wi sh to...

The Symmar-S takes a 77mm filter and the APO Symmar takes 72mm. The APO was noticeably sharper and contrastier than the S-S but the Symmar S was sharp and contrasty enough.

Mike <- 10...

I've used pre-exposure with Velvia to cut down the contrast. It works quite well up to about 1 stop of reduced brightness. On the occasions that I use it, I set up the camera with all movements,...

Ellis, I thought you were kidding when I read what I thought was your second po st. You should nail him. AOL will not look kindly on that kind of behaviour. This was a fairly innocent instance but...

I've only been using the 150 "S" for about a month. However, I photographed a Ni kkor 300M lens and filled about 80-90% of the frame on the diagonal (lens was mounted on a lensboard). I don't k now...

I've been using the Calumet 4x loupe (which is made by Rodenstock) for about 4 years and it has worked great. The wider field also allows it work well on the light box.

A pane of glass 4x5" in size can be held against the flat surface of the back if you cannot attach a metal plate to the dial caliper. (It must be something that does not flex.) In this case you must...

It's, of course, not totally impossible for an mfg to have something wrong or a lens to be out of whack (or is that "in whack" if it's wrong?) However, I would certainly suspect something other than...

Just to prove how right Ellis's statement is, after all the hours I spent once i n calibrating, checking, rechecking, emailing, etc., it turned out the previous owner had simply installed the screen...

The ground side of the glass should face the lens.

As I recall, the depth should be .192" +/- .007. A fresnel or after market scre en may change the depth required. Didn't the early Technicas...

While I haven't had the two you are considering, I have owned the 125 F8 and sti ll own the 250 F6.3. Both are very sharp with excellent contrast. If you look throughout the Fuji line, you'll find...

I think I know exactly what you're talking about. When I look at a medium format image, I simply feel like I'm viewing a transparency. When I'm evaluating a 4x5 chrome, I feel as though I'm in the...

I admire you guys for using an 8x10 in the field. The only time I've seen it done was by a less experienced 8x10 person and, frankly, it seemed a laborious, daunting pursuit.

Naturally, I don't...

I've had pretty good luck with a Calumet 4x loupe made by Rodenstock. The Toyo was crisper and about 1/2 the price. But, the wider field of the Calumet has been an aid to me, possibly because of...

I had my hands on one once at a local dealers and it looked to be a very nicely made, sturdy camera. I do not recall the movements it had but I suggest you confirm it has tilt and rise (pretty sure...

For what it's worth, I've use a Beattie on a Pentax 67 and on a Tachihara. As a comparison, I now have a fresnel with my Toyo AX.

Without doubt the Beattie is brighter. In fact, with a Tachihara...

The problem with writing newsgroups posts on the spur of the moment is clarity. On rereading the post I entered, the impression may be given that tilt isn't usable with a tele-design lens. That is...

I live in Ft. Lauderdale, FL and do occasionally worry about the humidities effect on my equipment. There are much damper places than even here and you don't say where you live.

My concerns have...

My personal opinion is that you would be happier with a conventional lens from 250mm to 300mm unless you have a severely restricted bellows.

I use a 250 Fuji CW-M and find the focal length...

IMHO you can't go wrong with the Tachihara. I do strongly suggest a new one. I don't know when they added the nylon washers and the little tab that helps keep the front standard more secure, but...

You might also consider the Tachihara, which you should be able to find at a reputable dealer even if in the US. Payment could be made by credit card. Shipping would be somewhat expensive due to...

I had the chance to handle a new Tachihara today. Someone posted that the new on es had the nylon washers installed at the factory and that is correct (not that I doubted it).

There were other...
