Default Lens advice.....

Here is the situation.

I am about ready to go and buy a new lens. It will be a wide angle and it will be a Canon L lens. Those are the two things I known for sure.

Now, the problem is timing and the 1.6 crop factor of Canon cameras.

1. I currently have a Canon 20D.
2. I am PLANNING to (but am not quite sure yet if I will) buy a Canon 5D. This is important.
3. Before I buy a new body I am going to purchase a lens.

Now the dilemma.

If I get the 17-40 f/4L it will be a great lens on my 20D. It will be around 27mm at widest, something Im very used to. I have a 17-35 Tamron lens now which is quite good.

If I get the 24-70L or 24-105L they will be awesome on a 5D but useless on a 20D for me (the 24 would become almost a 40mm focal lenght and I need a wide angle)

If I get the 17-40 and then get the 5D that would be quite wide. Im prepared to try that though, I think.

The again, I might end up getting the 30D:)

So thats my dilemma. What would you do? Wait till I have money for both a 5D and a 24-70 at one go?:)

How is the 17-40 on a 5D?

Why not a 16-35L F2.8 II? Recent reviews I read where very good..it performs better than the older 16-35 (yeah I read Canon lens reviews :))) ) maybe to expensive for you??

Another point is..Ask youself : Why would I get a 30D if I have a 20D?
It's not such a major upgrade, then wait for a 40D.
Else save more for a 5D which has more advantages, excellent noise performance, full-frame, bigger view finder, etc

A 24-105 will give you a nice range on a 5D..a 24-70 aswell, although a bit shorter ofcourse.
17-40 on a 5D should be very wide..but when you have it you'll probably find occasions to use that.

I love my 17-40L on the 30D and have the feeling that would love it even more if I had a 5D. For me, it's the market budget L lens. For the street it's a bit slower (in low light conditions) sometimes, but I love to use it. The focus is incredibly fast and the luminosity and sharpness is what you expect from a L lens. Nowadays, I carry it all the time.
I am buying my second L these days and it will be the 24-105. I thought it over the 24-70 but after weighting the pros and cons decided to go with the 24-105. But I wouldn't buy it before the 17-40...

Concerning the 30D... don't trade yours for this one. You really don't get much more than what you already have. Save the money for the 5D and buy the 17-40L.

If you want to buy a 5D then there is only one advice....buy the best glass there is. Those FF camera's (also his big brother the 1Ds) are asking a lot when it comes to quality of the glass.
When you have the money buy the 24-70m/m, although he is heavey, it's worth every euro.
Of course the other lenses also are good like the 17-40 and the 24-105, but in the corners, espcially on ff camera's they have some softness.

Don't buy ther 30D, the step forward is nothing compared to your 20D, then it is wise to wait for the 40D and see what that thing brings.

There are a few her that use the 17-40 and 24-105 on the 5D...maybe you should ask Luko about it.

Regards,

Henk

I would buy a full frame camera, the 5D or its successor.
I had the 17-40 lens, on my 20D is was very good, a bit short on the tele end though. I tried to use it on the 5D late - that was painful, terrible distortions and very limited range, not a lens you would use for the whole day.
I would get the 24-105, on your 20D it will be line 38mm - is not that narrow, I used to shoot with a prime 24mm f/2.8 lens on 20D - it was fine. then after you get the 5D you will have a perfect combination.

or just use what you have and buy 5D + 24-105 together. do you really need a new lens for your 20D?

but before buying any lens you have to decide whether you will use it on a full frame or small sensor camera. I made my decision and I stick to full frame cameras now

That may be the best idea. Just save up cash and buy it all at once. Ofcourse full frame is what I want to stay with..although I dont know..its tough:)

38mm is too narrow...much to narrow...

As you might have seen, I use both on my 5D.

I don't have the same opinion about the 17/40 on the 5D than Maciek, of course it can be peculiar and it distorts, like any very wide angle will, but if you don't have his reservations against distorsion, like I don't, I think it's an interesting alternative which I find more contrasty than the 24-105/4 at the wide focal ends, like 24 or 28 for instance.

More over the 17/40 is much resistant to flare unlike the 24-105, I also find it focuses faster... on the other side, 40mm is really too short and it doesn't have that fantastic IS feature.

Talking about glass quality, the 24/70 2.8L beats them all.

It's really a pity that Canon hasn't gathered all the benefits of these lens in a single one :
- 17/40L wide range, lightness and contrast
- 24/70L aperture and glass quality
- 24/105L IS feature.

... that's it : I'd like a 20-85/2.8L IS, puleeeeze Mr.Canon...

I agree with Luko about the 17-40 on the 5D. Although I never used one on a FF body, I've seen his and also Adam Burton's photos and the results are impressive. Distortion you will get with all these wide angle zooms. I guess it's all a matter of taste like Luko says. I like the feeling...

If you have no problem with weighty equipement, rafal, i'd go for anything that gives me f/2.8 aperture possible. that's 16-35, not 17-40 and 24-70 instead of 24-105. I got stuck many times at f/4 when I needed that extra light or speed, last trip. On the other hand, the 5D has good high ISO rating, and you affectionate the grainy film look, I think, so f/4 at ISO 800+ might give you the speed and light you need. But it's already a compromise, and you are about to spend $$ for a 5D and a L lens. Why compromise... Go f/2.8, whatever lens, is my 2 pennies.
