Upgrading from 300D to 10D need a lens to replace 18-55mm

[leehal]

I didn't realise that the lens that came with my 300D cannot be used on the 10D unless it is modified (and probably not worth using ?).

Can anyone recommend a replacement lens that isn't too expensive - bit skint at the moment ! :shock:

There's always the Sigma 18-125. It's under $300 IIRC. If you get the money, the 17-40L is very nice and not that expensive for an L lens, about $700.

The 24-85 f3.5-4.5.

If you don't already have a prime lens, why not get yourself a Canon 50mm 1.8 Mk II and use that for a bit until you can afford a decent zoom. It's very cheap, and very good, but it doesn't zoom :D

When I bought my D60 a little over 2.5 years ago, I had to pick a lense for I had none to go with the camera, fortunately the one I got was the 28-135 IS USM. I absolutely love it, it is the main lense for my camera, the only time i take it off is to take a couple of shots that require a different lense, but then it goes right back on. Yes with the 1.6x conversion it did not really allow for close ups with a good field of view, but don't think I could really live without that one, nor would I want to. As you can see from my list I have a few other lenses now, but that one was my first.

I already have :-

70 - 200mm 4.0FL
50mm 1.8FL

And want to take wide angle shots :D

the 17-40L is a wonderful lens
but the 78mm filters are a little pricy...j

Ok, well either I missed it in your original post, or it wasn't there, that you already had those lenses. I like my Sigma 12-24mm but I think that is more then you wanted to spend, it has a fantastic 122 degree field of view at 12mm, but am wondering if I would not have been better off getting the 16-35mm L with a little less field of view. Guess I will never know unless I ever get a chance to try them side by side.

I´m still missing a wide angle lens in my collection for my 10D. The next lens i´m going for is the EF 17-40L.

How about you?

The sigma 18-125 is a DC lens, which probably means that it is designed for a 1.6 crop factor. Does anyone know what happens if it's used on a camera which has a better crop factor of say, 1.3 or even 1.0?

Sorry Raman... can´t answer your question. I´ve been wondering myself. But i´m going to stick with Canon Lenses. Why? Well someday when full frame DSLR bodys are available at a affordable price, i´ll get one. Hopefully they will still have EF mounts! Then i´ll be able to use all my Canon lenses. If i would have lenses specially bulid for 1.6 or any other crop factor, then i would need to start all over selling and buying new lenses. And with non Canon lenses i would maybe have to (if possible) get the lenses rechipped.

I could be wrong tough !?

Sigma 18-50DC is a cheap solution. I find it quite soft, but gives a nice wide field of view whilst I'm saving up for a trip to the US to buy a 17-40L.

UK price is about 99 pounds, it's not a bad lens for the price, but it's not a good one :-)

Note that the DC lens is 'optimised' for the 1.6 crop factor of the current range of digitals - it won't be much use if you ever get a full frame sensor digital.

I think it will just give you a wider angle of view but less zoom. I don't know if DC lenses are specifically *designed* for digital cameras...I think they are just "labeled" for digital camera use ... for instance a 12 mm normal lens is like an 18 mm lens with a 1.6 crop, so perhaps they just build a 12 mm lens and label it as an 18 mm lens instead of labeling it as 12 mm. I have no idea though.

Thanks for your comments, going to wait until my trip to the USA in September and get a Canon 17-40mm f/4L

Cheers,

There was another thread about this a few days ago. DC means you can only use the lens properly on a digital camera with APS-sized sensor (a crop factor of 1.6x (Canon) or 1.5x (Nikon)). You cannot use them on 1.3x or 1.0x cameras. From Sigma's website:

DC lenses: Theses are special lenses that are designated for interchangeable lens type SLR digital cameras because the lens image circle is designated to correspond to the size of the image sensors of most interchangeable lens type digital SLR cameras.
The specialized design gives these lenses the ideal properties for digital cameras.

An image sensor element larger than than those corresponding to APS-C cannot be used in digital cameras or 35mm film cameras. If such an element is used vignetting will occur for digital cameras.

Actual angle of view will be different depend on the camera image sensor size.

About the 18-125: I think it's not yet available, it should be available from September 2004. According to Sigma's description (http://www.sigmaphoto.com/Html/18-125.htm) it's exclusively designed for digital cameras. "Image circle is designed to match the size of the image sensor of digital SLR cameras." In other words, not full-frame.

Saw the following on the "Features" tab of 18-125 sigma lens on b&h site (does not look like a feature to me though :shock: ):

Note: Not compatible with 35mm cameras or digital cameras using full-size image sensors (e.g. Kodak DCS14n or DCS PRO SLR/n).

i have the 17-40L

i opted for it rather than spending $500 more on the 16-35... i think for me the extra stop will be well worth it on a longer lens...
