End of an Era?

Pyre of Fyre · 18th August 2004

Hi all, just wondering, with the influx of the new EF-S lenses coming into the market, would the current existing EF lenses slowly be put to waste like Canon's previous mountings like FL, FD and so on?

What's going to happen to the current lenses that I've accumulated? And what about maintenance and customer service?

POF

Most definately NOT.

EF-s will only work on the 1.6x digital bodies.

In the future, everything will be full frame, no more 1.6x. So EF will be around for some time yet.

So now you've got me confused... What's the difference again between an EF and an EF-S lens? Is there anyway to mount an EF-S onto an EF body through some form of adapter or something?

POF

EF-s lenses are built specially for use with 1.6x digital bodies, because the size of the sensor used on such bodies is smaller than full-frame/35mm film.

EF lenses can be used with 1.6x digital bodies, as in they are compatable with, but they were built with 35mm in mind. Hence some of the glass in an EF lens will not be 'used' in the image which is captured on a 1.6x digital body, because the sensor is smaller that 35mm.

You can try reading the link below and see if you get a clearer idea regarding sensor sizes, and what the relation so EF-s and EF lenses that means.

Hi POF,

I was also confused initially with the 1.3x or 1.6x factor of digital bodies. What I have figured is that it is NOT a magnification factor but a cropping factor. If you can figure out the difference btn the 2, you are 1/2 way there.

Cheers!

Or maybe there'll be EF-S XXXmm L lens?

Doubt it since EF-S is for consumer market.... but then again I might be wrong since Canon has made pro1 attach with L lens (but quality is suspectable).

yes if thick black boarders become fashionalbe on flim prints.
yes if they make smaller more high definition film. APS sized.

Have you all forgoten about film?

And what about maintenance and customer service?
I just saw someone bring in the canon lens that was the same model used on the moon, the 50mm... something i cant remember.. anyway this nice older lady was bringing it to service. So i dont think Canon is going to say no to your EF 14mm L or your EF 50mm 1.8 anytime soon.

Why make an EF-S L lens? Doesnt really make sense. Then again... who knows...

EF-S because it doesn't need to produce a FF size image circle, (ie: only 1.6x smaller size image circle) uses less GLASS and Less material, thus is cheaper/lighter .

so its a way for consumer's to afford wide angles.. (albeit the EFS10-22 is USD799)

From what I see, it would seem that the new 10-22 EF-S lens does have some properties of a L lens, but not all. One thing it is a variable aperture lens. Another thing is that it does not seem to be DWR. However, it does employ the optical elements present in most L lenses like Super UD elements and aspherical elements. Granted that for such a lens, they will need to use elements like this as the distortion will be pretty severe. However, I think from an image quality perspective, it should compete quite close to that of a L, but not L. Just like the 70-300 DO, which has a high end DO element, but yet not classified as a L due to the lack of weather sealing and constant aperture. Granted the 70-300 DO may not produce an IQ as good as most L, but it's a pretty decent lens. The 10-22..employing such elements should produce pretty decent quality too.

In general, to be classified as a L lens, the lens must have certain features and also meet a level of performance. The new EF-S lens may not have all those features and requirements, and may not produce an IQ as high as most L, but i believe in terms of IQ, it should compete pretty well..

Just my 2 cents..

USD799? that is more than 1 k in sing dollars! How disappointing!

Pretty cheap, in this case, isn't it?
Of course, I'm comparing it to a 35mm equivalent lens, the 16-35mm L.

Anyway, you still can use EF lenses on EF-S mount cameras. Also, there's still the EOS 1Ds to think off--a full-frame DSLR that requires EF lenses.
