Yes.

Velvia 100 (not 100F) LF film is not available even in Japan. 35mm and 120/220 only.

He is the chairman of JAPA (Japan Alpine Photographers Association).<br>

I have searched Japanese and English web-sites for days but can not find out his nor JAPA's web-site except for the following info of JAPA.

Used 550EX price would be 25000 - 30000 yen (US$210-250) plus 5% tax, and no shop warranty is available for overseas (out of Japan) use.

The MSRP was formally announced in Japan for 162,000 yen (about US$1350).

So what? Don't you need full 36mm x 24mm images? If you do so, you will get vignetting images.

Sigma 15-30 does not have filter thread. It has a gelatin filter holder on the rear. So you can't use 82mm filter on that.

It's not 1:1 but 1:2 macro lens, and does not work on EOS3 or newer EOS body without re-chipping. I'm not sure whether SIGMA will re-chip it.

The identical question was made by a Japanese camera magazine to Canon when 1v was released. Canon answered "No", and said "though sealing performance is much better than 1n, it's not waterproof. Using 1v in a rainstorm may cause trouble."

I have just found the news bellow at a Japanese website, and would

like to inform you in this forum.

 

"Sakai Special Camera MFG. CO. LTD, the manufacturer of TOYO VIEW and

TOYO FIELD closed their business on October 31, 2002. A new company,

Sakai Machine & Tools inc. is taking over the operations of sales and

service of TOYO cameras."

 

There is no clear description whether the new company will develop

new TOYO cameras in the future. The announcement said just sales and

service operations to be taken over by the new company.

Sorry, I might be wrong. The RING USM system is a kind of differential gear system, but small RING USM has rollers instead of gears.

The RING USM system (not USM Motor) do have the gears which enable us FTM focus. So Cathrine's problem on EF100mm F2.8 Macro USM is not impossible.

Nikon 14mm F2.8 is made by Tamron. It's OEM product and optical design is identical with Tamron 14mm.

But lens coating spec. is different and it is said Nikon has better coating.

Discussions here are very interesting, but I don't think data source is solid. I'm working at a manufacturer (not Canon) and am in charge of long term product strategy and planning. We never leak long term plan to dealers, even not to sales division inside the company and we let any rumor as it goes. But it should be true, as the previous post mentioned, Canon will not need to update EOS-1V for years and engineers are working for other cameras today. It does not mean Canon has decided to produce no more pro film cameras in the future.

 

 

As to a "self-proclaimed" Canon's engineer emerging in a Japanese forum, they are busy on developing Kiss (Rebel) Digital and EOS-1Dx. So 1Ds will soon be old, as is always the case with digital cam. And, I guess Kiss 5 LCD layout should be designed not for a big indicator of film camera but for a viewer of digital cam. It's just for your info.

Everyone might misunderstand TOYO 45CF. TOYO explains it's body construction as follows in TOYO's web-site.

 

 

We are pleased to announce the launch of the new TOYO 45CF (TOYO 45A board version) / 45CFL (Linhof board version). We have realized light weight by applying plastic to the body parts, but we use metals to all the parts where rigidity is required.

Toyo45A-Linhof adapter lens board; Part No. 1631 AL4F.

Toyo45A-Horseman adapter lens board; Part No. 1632 AH4F.

 

These are available from Toyo and you can fit Linhof or Horseman board on your Toyo Field 4x5.

The later version of 45A has universal back but the earlier version 45A does not. Neither of 45A has revolving back (it was optional). You�fd better check the back of used one you�fve found, as you may have difficulties to use roll film holder without universal back.

I have 45A with universal back and am very happy with it.

Discontinuation of EF50/1.0L was formally announced in Japan.

I'm afraid you can't attach Canon 1.4x extender to Sigma 70-200 f2.8 EX. Because Canon 1.4x front element comes out more than Sigma x1.4 EX telecomverter. And when I compared my EF70-200 f2.8L and Sigma 70-200 f2.8EX, Canon has bigger recess of the rear element.

Ni-MH surely has the memory effect, though it's smaller than that of Ni-Cd. Rechargeable battery without memory effect is lithium-ion.

DOF of 200mm f2.8 @ 2m is approx. 1.6cm.

 

I have this lens too. It's very sharp at f2.8 if a subject stays within DOF.

Output of alkaline AA battery is initially 1.5V but is continuously decreasing as it being discharged and finally down to 0.9V. Shortly after starting discharge, output of alkaline battery falls bellow 1.2V. Ni-MH (and Ni-Cd), on the other hand, has 1.45+-V output initially and soon falls to 1.2V and keeps 1.2V till its life end. Actually alkaline has lower voltage than Ni-MH in the real usage. So Ni-MH should have no problem in terms of low voltage.

 

I enjoy Ni-MH with my EOS3 and BP-E1, and have had no problem for years.

I agree with the above three gentlemen, and I put BP-E1 battery pack instead of PB-E2 for landscape work to save weight and for capability of using AA batteries. BP-E1 can hold 4 AA batteries and 2CR5 lithium together. When AA batteries come to dead, all you need is just to turn the switch to 2CR5 and you can continue taking photos.

FYI, Toyo 45CF comes takes Toyo Field type lensboards (110x110mm) and 45CFL takes Linhof type lensboards.
