EOS 50,50e &55

greenspun.com : LUSENET : Canon EOS FAQ forum : One Thread

i know that eos 50e is the eye-controlled version of eos 50 but how about eos 55?Also what's the difference between 500 and 500N ? did canon produce a medium-to-tele lens(focal length forgotten)at constant aperture of f/4? i read from some books that EV is calculated by logarithm,is that true? wide opening aperture creates the effect of background which portraiture requires,will tele lens (eg.100,135,200mm)do so? Thanks

Yikes. What a pile of questions. Let's see if I can answer any:

1) The EOS 55 is what the EOS 50/50E (Elan II/IIE) was called on the Japanese market. It had eye control, date back and a panorama mask which, like APS panorama, simply masked off a chunk of the negative and so altered the aspect ratio of the image at the cost of losing a big part of the image area. The EOS 55 was made in groovy-looking solid black as well as the usual black/aluminium of the EOS 50. I don't know of any other differences because I've never seen one and thus am less than an authoritative source of information on the topic.

A couple people have mentioned recently on the EOS list that they like the panorama mask not for panoramas but because the panorama lines in the viewfinder serve as useful horizontal grid lines. I've noticed that KEH.com occasionally has an EOS 55 to offer.

2) The EOS 500 is the Rebel X S in North America. The EOS 500N is the Rebel G in North America.

3) Yes. Like the EF70-200mm f/4L USM (still available) and the EF70-210mm f/4. (now discontinued, I think) You can look up those zoom lenses at:

4) A smarter person than me will have to tell you the answer.

5) Longer lenses have basically a shallower depth of field effect in photos, yes.

Not necessarily smarter - just happen to have the answer :-)

Yes, EVs are logarithmic. Each change of 1 EV represents a factor of 2 change in light level - EV 11 is twice as bright as EV 10, for example.

Not so much an answer as a further query prompted by the earlier discussion: I do like the facility of being able to shoot 'panoramic', even tho it is on a small piece of film. So much so that I carry a compact with that facility together with my Canon gear. But I would dearly love an EOS that was designed for that. apart from the elusive '55', can anyone tell me of any more widely available models that permit that?

Cheers JIM

Legnum,

I don't think Canon has stopped producing their APS EOS SLR bodies, have they? The EOS X & X Lite or some such. They accept all or most of the EOS lenses, and give you 3 different shooting formats (including panoramic) to choose from -- and you can switch as often as you want on the roll! Carry one of those bodies with you, and you can use the same lenses between the two bodies!

Did you know that you can have any 35mm negative printed in "panoramic" format at just about any lab? The machine will simply print what's in the middle 1/3rd horizontal segment of whichever negative frame you want -- what you are missing are the frame guides in the viewfinder to help you compose that shot.
