EOS 20D Lens Support

[bryanfisher]

Hi,

I'm new to the forum, and have looked around for this question, but can't find it, so if it's been covered before, forgive me...

I have an EOS IX (APS SLR) and a couple of lenses (quantaray 70-300mm and canon ef 22-55mm)

I will be lucky enough to receive the 20D for Christmas this year, and my question is will my current lenses be compatible with it? Should I keep them, or should I just buy new lenses anyway?

thanks!

Welcome to the forum.

Compatibility depends on how old the Quantaray is. Some older 3rd party lenses don't have all the functionality of Canon's EF lenses, and may lock up, or lock the camera (Err 99 is the commonest message). It won't break anything if it happens, but you won't be able to use the lens, and may have to turn the camera off or pop the battery to get bake in operation. Sigma has offered to re-chip older (but not oldest) Sigma lenses that were incompatible with the newer EOS cameras, but I've never heard of Quantaray doing anything similar. The Canon should work OK. They're both cheap lenses (sorry!) though, I'm afraid. Some people here will tell you to run away from any Quantaray lens, in fact. If they do both function OK with the 20D and you've been reasonably satisfied with the results you got from them on your IX, you can look at getting other lenses to complement them. If you're not really happy with one, the other, or both, this would be a good time to replace them, especially since Canon's got a very nice rebate program on now.

As you're already working in APS, you should have a pretty good feel for how these lenses'll frame on the 20D and you can safely disregard everything said on the board about the "crop factor" of lenses. In fact, if you're reading a thread and the phrase appears, you can safely stop reading - nothing from then on will be of any real value to you.

Thanks for the reply!

i realize that the lenses are cheap-o's, so i suppose i might as well upgrade.

It seems that a lot of the 20D "packages" that ship with a lens or two all come with different lenses...i've heard good things about the EFS 18-55mm lens...is there something that you would reccommend for a good all around lens?

thanks again

I love my Tamron 28-75 F2.8 for a good all-around lens.

Are you keeping the IX? If so, the 18-55 wouldn't work on it, so you'd end up carrying around both that and the 22-55. I'd guess (don't think anyone's done a head-to-head comparison) the 18-55 isn't going to be a lot different from your 22-55. There are a number of people here who like the Tamron 28-75 f/2.8, and it often seems like the only people here who wouldn't tell you to get the 50 f/1.8 are those who tell you to get the 50 f/1.4 instead. On the rebate list, (since you're getting the 20D, you already qualify, I think, for double rebate with one lens) the 17-40 f/4 L is very good. A number of people like the 28-135 IS for a walk-around lens. The 75-300 IS isn't a bad lens, not the absolute highest quality but it doesn't claim to be either. How much do you work at the wide end of your lens range? At the telephoto end? Let that be a guide as to where you'd like to concentrate your lens effort.

What's in my bag? Sigma 15-30, Tokina 19-35, Canon 28-90 (came with the Elan 7), Canon 35 f/2, Tamron 90 macro, Canon 75-300 IS, and Canon 100-400 L. 50 f/1.8 on order.

thanks for the responses!

looks like i have a lot more research and soul searching to do..

Jon- i will probably keep my IX, but also will probably not really shoot with it much. and i suppose i shoot more in the wide-angle range, but i'm a fan of experimenting and shooting as much as i can as differently as i can.

for what is worth..........I bought the 20 D body without a "kit" lens. I already had the 22 - 55 that I was using on a film camera. I used the 22 - 55 to "learn" the 20 D. For being a "cheap" lens it worked VERY WELL. You might want to consider doing the same and putting the $$ you save from buying the "kit" towards a nicer chunk of glass or some other goodies.

many of the shots in this gallery were done with the 22 - 55

I susect there is a very good chance that the Quantaray will indeed NOT function... as described in Jon's response. Many of the Quantaray lenses were Older discontinued Sigma designs being ade for Ritz. And these old Sigma's are the most likely to have problems with new DSLRs.

Although you are already getting the 20D, if you need new lenses don't overlook the drebel and lens rebates. Get a great camera and da kine L lenses for that "20D+ "later"
It's a steal if you need them, or give the cheap rebel for a present...

If I'm reading the rebate certificate correctly, the 20D counts as "one" for the rebate program. $0, but means the first qualifying lens is good for 2X rebate, 2nd means 3X rebate.
