Toyo 45A 45AII 45AX and 45CF Resource/Fan Page

According to the specs, the CF bellows if longer than the bellows on the AX and will accommodate a 400mm lens vs a 360. I also own the AX (same as the AII) which I assume is similar to the A.

The CF bellows are indeed longer at 356mm, vs. 324mm for the AII. I believe the CF cannot accept the extension backs that can be used with the other A models. The AX is the same as the AII, except that it has a reversible back, not a rotating back. It is the same difference between the A and the AR.

As a reference I was checking the GG of the Toyo 45CF and it appears to have a stock GG sandwich of Ground-Glass on the outside Fresnel on the inside. Upon further examination it seems I may have a 9x12cm back, because it crops the 4x5 down to 9x12.

The back of the glass is shiny, there is a matte surface on the interior side which rests on the left and right 9cm sides (horizontal) on a machined aluminum surface (looks like two silver rails at the focal plane). Inboard of this matte glass is the ring-etched fresnel surface of the clear plastic fresnel lens. The fresnel is not as wide and stops just short of sitting on the aluminum rails at the focal plane. The polished-smooth side of the fresnel lens faces the inside of the bellows and lens. The Toyo View script on the bottom right of the fresnel reads correctly from behind the camera (through the matte GG). This two piece sandwich is held together by two deep black U-channels top and bottom.

Toyo GG and 9x12 springback

The 12cm wide side of the Toyo Glass is 126.25mm and as near as I can measure the space it fits into between aluminum hard stops on the spring back is 127.5mm* ( I have a Cambo 4x5 GG and that is 125mm wide exactly and it fits onto the focal plane rails (which are 122.75mm apart). It will work in a pinch, if you aren't careful it could slide and fall into the space between the aluminum focal plane rails. But I will use it as a backup fo now- The Toyo GG did not work on the Cambo, it is 1mm to wide)

I could believe if this 9x12cm GG is the same actual "glass" as the 4x5 springback with a different mount, back and channels and perhaps the u-channels at the top and bottom might not be so deep on the 4x5. Let me know if that's the case. I'm an old hand at Cambo but new to Toyo this month, except for the 8x10 G that I rarely use. I believe the Toyo and Horseman 4x5 and 5x7 GG are the same but I may be mistaken.

Do the specs say it can accommodate a 400mm or a 400mm Telephoto?

[tgtaylor]

The specs say that it will accomadate a 400mm lens but I never used beyond a 300 with it. The Fresnel was a option and after a year or so I installed a Fresnel out of a Toyo 45 C ordering the spacer set from MAC group. The 45C back is not interchangeable with other Toyo cameras ( so I can't use the Robos's revolving back with it as I can with the AX) and it won't crop a 4x5 negative.

I dug up a CF manual and it says 360mm max non-telephoto, but also has applicable telephoto lenses out to 500mm Tele Congo.

Bellows arrived... note the special taper and the smaller ribs where the bellows tucks under and into the 45CF or 45 A body.

Has anyone heard of World Field 45F? It looks just like a Toyo 45A. I found this one on eBay. It came out of South Korea. I have searched the web and come up with nothing on them. It had a bad pinion shaft. I ordered a replacement for a 45A from MAC Group and it fits and works perfectly.
Just wondering if Toyo cameras were sold under a different name or where this camera came from?

[B.S.Kumar]

Toyo view cameras were sold under the Omega brand name in the US for some time, but not the field cameras, to the best of my knowledge.
This camera may be a copy, just like the Penta (also out of South Korea) is/was a copy of the Wista 45N. The leatherette seems to have been applied rather clumsily, so it may actually be a Toyo 45A with a new covering.
