My personal opinion:
I have a Sigma 17-35 EX and I do not see on the lens or in the box
anything close to "Canon EOS certified" this means to me that they are
on their own in terms of design and meting specs. The difference in
price that you save, you pay it in the risk of buying 3rd party.
Do you think Sigma knows Canon R&D plans? How can they assure
compatibility?
I'm not an expert like you guys but my sigma does not work well with my
1v, it's a problem with AF. I should've saved more money to buy a Canon
lens
Anyway, my 2 cts
Have a nice day (or night, or evening)
Help me understand - why do old Canon lenses work and not Sigma?
Did Sigma not design to Canon's specs? Did Sigma have to guess what the
specs were and guessed wrong. Do you want cameras not to improve
because it
might make some accessory unusable?
If you develop a product and lots of people make accessories to
attach to it and, of course, pay you nothing for attaching. Then is it
really your responsibility, when you come out with an updated version,
to
test it with all of the accessories which have appeared to be sure your
product works with them. I think if you published your specifications,
others designed to those specifications and they were tested to the
specs,
then there is some room for complaint. But if the specs were never
released
(which suspect is the case) and some company chose to design for that
product, and you decided to buy (that lens for that product) I don't
understand where the complaint is. You got the lens for a camera, it
worked
well and you were happy with it, and you saved money. If does not work
on
the next camera - I understand the wish that it had done so, but I don't
see
it as anyone's "fault". If it is anyone's fault I think it is yours.
You
bought something advertised to work with a camera, it did, and now you
want
to blame someone else because it does not do more.
