Hello all,

I'm brand new to SLR photography. In fact, I haven't even bought any
equipment yet, but I'm doing all the research now. I'm very confident
that I'm going to buy the Canon Rebel XTi body, and I'm about 50%
confident that I'm going to buy the Canon EF-S 17-85mm f/4-5.6 IS USM
lens (I'm debating between that and the more expensive Canon EF
24-105mm f/4 L IS USM). My question is that if I buy the 17-85mm lens,
what real benefit would I get from buying the Canon 10-22mm ultra wide-
angle lens? I want to take a lot of landscape shots and only want to
invest in the additional lens if it's really going to make a
difference. Also, any other advice on what I should be considering
would be greatly appreciated.

Thanks in advance,
Shannon

I have the 17-85 is and like the lens very much (and can't justify the
L lenses due to price) but one thing you have to remember is that on
these digital SLR's the sensor is less than full frame (in relation to
a 35mm film SLR) and as such have a focal length multiplier..

So, the 17-85mm is really equivalent to a 27-136mm lens. Much less wide
than you may have initially thought. That makes the 10-22mm lens a
16-35mm lens and may be approaching the wide angle you were expecting.

Then again, if you know about the focal length multiplier you can
disregard everything I've said..

Thank you so much! That is actually quite helpful in making my
decision and in my overall learning. I'm vaguely aware of the focal
length multiplier. I read it's definition but haven't found (or even
looked for) a practical example of how it's used. Therefore, I did not
take that into account. That makes me confident that if I buy the lens
I won't be wasting my money (or at least it's worth giving a shot).

Thanks again,
Shannon

Thanks for the reply, Tom! The wide angles on those are impressive.
How impressed have you been with it? Also, what do you use for viewing
CR2 files? I assume Photoshop but I don't have a copy of that. I tried
a free program that installs a Windows shell extension so you can view
it as a thumbnail, but I can't open it full size.

Thanks again,
Shannon

L glass is worth every penny. I have a friend with the 17-85 and I have the
24-105, it is easy to see which lens took which picture. The only drawbacks
to the 24-105 is it's size and obviously it's price. If you don't need the
long reach, the 17-40 f4 L is a better match to the smaller XTi. If you
don't need the wider angle of the 17-40, the 24-105 does an acceptable job
and nothing stops you from stitching two or three shots together to make a
panoramic shot.

On a recent trip, my wife used a 17-40 on her Xti and I used a 24-105 on a
20D. Only a few times did I wish for more of a wide angle, but the pictures
I took and stitched looked great. On the other hand, the longer reach of
the 24-105 and the IS were more useful to me.

Buying cheap is not always a good move, you may spend more when you do get
the best product in the end.

Stop this myth, you are cropping! You aren't multiplying the focal
length. If I had a 1.5X teleconverter (presuming they existed) and
mounted on a 50mm lens on a 24x36mm film or dSLR I would have a 150mm
lens. If I mount a 50mm on a APS-C sensor like a Nikon D80 etc, I would
only have a 50mm lens, but the field-of-view would be cropped. If I put
the same 50mm lens on a 35mm SLR and looked at the same scene from the
same vantage point the perspective would be the same. Shoot print the
dSLR to 5x8, print the 35mm to 8x12, and cut a 5x8 from the center of
the 8x12, and then shot the exact same thing with a 100mm on the 35
print that at 5x8 it will have a different perspective than the other
two examples.

You are cropping not multiplying...

Thanks for the input Jean. I completely agree, as I am always willing
to spend a little more to get something I want. I'm just weighing a
lot of decisions regarding the lenses (because I'm planning to buy up
to five) and hoping that the 17-85 will be enough for me. Clearly, my
cart total is skyrocketing! Therefore, I keep flip-flopping between
the 17-85 and the 24-105. I also have a little voice in my head that
tells me whichever one I pick will be my primary lens, and I should
invest more in it to get the best quality. Here are the lenses I'm
considering getting (all Canon brand):

100mm macro
10-22mm ultra wide-angle
17-85mm IS or 24-105mm IS standard zoom
70-300mm IS telephoto
50mm f1.8 prime lens (only because it's cheap, has a wide aperture,
and is highly recommended by customers on Amazon)

How do you feel about this list? Are any of them unnecessary or not
very useful? In my mind I can imagine different scenarios where each
would be useful, but like I said, I have no experience.

Thanks again,
Shannon

Thanks, Tony! That's very helpful because I'd hate to make a decision
I regret.

And still, some of the sharpest and best Canon lenses are not "L" specified!
The 50/1.4 for example!

Would you mind expanding on that a bit? I understand the basics on DOF
and lens/sensor, but that's about it.

You are welcome and glad to see someone actually looked at them Smile.

Well my talking about how much I like anything in a camera is worth only
conversation.
I wouldn't suggest you go out and buy anything based on what I say. This is
my first DSLR
and this is the first camera that I have been shooting in Raw.

Those were actually my first outside pictures with this camera and lens.
and don't judge the 40d or the lens by the pictures I take.

hmmm so you only were able to see my pics in thumb nails?
I have just upgraded from elements 4.0 to Photoshop CS3 and love it.
If your computer can handle it you can down load trial versions of Photoshop
CS3
and get to use it for 30 days. but I would suggest is first down loaded the
trial of Elements
and get used to the basics after 30 days experience then treat your self to
CS3.

there are a number of programs that you can down load for 30 days.
but if you cant or just don't want to go with a paid version than its
probably best
you start with a free version.
being you used the term " Windows Shell Extension" you probably know more
about computers than I do.
but can offer some help in MS Office, Dreamweaver and dare I say Photoshop.

Am I correct in assuming that reducing the aperture one f stop will equalize the DOF?
