Michael,

actually it's not for sideway mount, it's for doing some back or front standard sideway movement of the field camera. I tried the univeral one, doesn't tight enough for preventing twist....

Michael,

u are absolutely right, they are borderline rude. When I ask why don't they provide better payment method, they said they have more than enough business right now, so ask me why do they ...

Hi all,

I got a Arca-Swiss type univeral quick release plate for my Toyo 45Aii, it got a one inch wide one mm deep grove in the middle, I was wondering if I can make a metal plate "L" in shape...

may be take off the back element

Hi Bod & J., thank you for the information. Right now I am using a Peak 22X loupe, a friend told me to use this one when I was new to LF. I know it's overkill now. But I am thinking if 4X is good...

I was consider to buy that too, now I take off the rear element of my apo-symmar 210 f5.6, this becomes 370mm f12, I will use it for the mean time before I find out I use it more than 20% of the...

Paul, thank your for the confirmatiom. Bod, are u saying the direct viewer has not enough magnification?

Regards. Chin.

Paul,

Thank you for the comments, I 'll have to find out if a Horseman direct viewer can installed to Toyo 45Aii.

Walter, thank you for your extensive opinion, and thanks Wilhelm for telling me the way that BTZS works. I may like to try to pleat elastic things on my horse blanket to try to simulate the BTZS,...

Nathan,

u are absolutely right, for no movement focus, since we are doing landscape, we will focus the 1/3 the distance from near to far point, so the absolute focus accuracy is not a concern...

Hi Steven, your concern is exactly my concern too. I don't have room for this binocular in my back pack, that means I have to spend another couple of hundred dollars to buy a bigger one. And I...

Hi Paul,

I use toyo 45 Aii, the bino is selling USD5xx at B&H.

Chin.

Hi all,

I take landscape exclusively. I find using dark cloth to focus is a bit slow som etimes. So I am thinking if a Binocular Reflex will help focusing.

My questions are how many of you find...

one more, I don't observe any noticeable difference in sharpness campare to phots taken with or without the back element as long as it's stop down to f/16 or more

It looks pretty sharp to me under a 8X loupe, it's more than expected, it's acceptable to me, i think i will still use it that way.

Thank you all. Chin.

With all u guys comment, I think I will process those scene that I am satisfied with, and throw away the others.

Roberto's idea is pretty interesting too, I will consider to add something to the...

Hi guys,

unfortunately, the pro-lab I usually go to close today, I'll have to wait til monday to let you guys know the result.

I stop down to f/22 which means the effective light is as dim as ...

Hi all,

Thank you for the responses, I tried my Apo-Symmar, looks like it works, under the ground glass, the image is OK, let me process the film, may be it will be not acceptable.

Chin.

Thank you for all your response.

Robert, I shoot transperancy. To save money, I havn't develop the 2nd exposure if the 1st one is fine. Looks like 2 out of 2 people (100%) will develop both, may...

Hi,

recently, I was notified that Symmar designed lens can have their front or back elements use separately. For example, my APO-Symmar 210 f/5.6 can become a 370mm f/12,

my question is how to...

should be "what" not "whay", sorry for the confusion, I should have check carefully.

Chin.

Hi all gentlements,

I usually shoot 2 identical exposure for backup pupose, but when the first one p rocess fine, if I throw away the backup, will I need it in the future? To keep it, a very well...

Hi Bill,

I tried it, it works. Thank you very much. But in order to have a good DOF i.e. a small COC, it have to be stop down 3~4 more stops, i.e f/36~48 which will make the exposure time too...

Dear William,

do u mean I can take off the rear element of the 210mm then it becomes a 370mm?

Thanks a lot. Chin.

Nathan,

u are right, I wouldn't want to carry a 10% usage lens with double the weight of another alternative. But another factor as u mentioned is I have only a Toyo45 Aii which provide a 324mm...

Wilhelm,

could u please tell me what is a convertible symmar? Is it something like a tele extender? Also where can I get more info and buy it?

Thank you very much. Chin.

Hi Michael, Nathaniel & others,

In Robert white, the Schneider APO Tele Xenar 400/f5.6 compact is almost the same price as Fujinon C450mm/f12.5, besides filters size and weight advantage, how...

Hi all,

I already have a 80, 120 & 210mm, I am thinking to buy a 400mm for some distant landscape which happened occasionally. But this will introduce a new set of filt ers (82mm) and carry an...

Sorry I havn't make myself clear, I mean how to origranize the films into pairs after shooting.

It will be too much to carry if all of them is sit in the holder duriing the trip, I usually just...

Hi all,

people usually shoot 2 identical shots a process one after another if it need to push or pull. With quick load, it's easy to identify which 2 are a pair, what a bout using normal sheet...

Hi all,

I think focusing with a dark cloth is too slow, it usually makes the interesting light gone. So I am thinking about either to use a monocular or a ballon focusi ng hood. I heard that it...

Ellis and others'

my loupe is a Peak 22X loupe, it doesn't focus when I reverse it, can u tell me what loupe u use? Sacripant suggest the Silvestri tilting loupe, I wonder should I get this one...

Ellis,

try to point the loupe more towards the center of the lens may lead to the loupe being not flaten or say not full contact with the fresnel screen, then the image is not focus through the...

Sandy,

when I use my 80mmF5.6 on my Toyo 45Aii, the found the rim very dark and it's very hard to check the focus for the upper and lower part of the fresnel screen with or without a loupe. I...

Glenn,

I still cannot figure how a binocular can facilitate focusing, especially on a tilt movement, can u explain more?

Thank you. Chin

Can u tell me how can a binocular enhance the speed of focus? Does it help speeding up tilt and focus as well?

Hi guys,

I am looking for a tilt & shift capable medium format for Landscape as a hobby ( may accumulate stock) and to replace my Mamiya 7 and 4x5 Toyo with Schneiders. T he reason being Mamiya 7...

I own a Toyo 45Aii, a schneider APO symmar 120 & 210mm, just want to get a wider lens like 75mm. But I am not sure if this lens will be in the way, cause me to drop the bed to avoid it?

If so, I...

Just want to make sure 75mm doesn't need drop bed on Toyo 45 Aii. Anyone have experience about that?

If it desn't need drop bed, than propably the Super Angulon 75mm f5.6 may be in a quite...

Hi Emil,

Thank you for your explanation, I become fully understand it now. And thank you for further comments too. I think I will not buy 65 or shorter for that tedious drop bed action. A 90mm...
