View Full Version : Suggest a good zoom lens for my 300D

05-08-2005, 03:03 PM
I just got a 300D as a gift. I have a 35mm Nikon (N65). I use my Nikon 70-300mm lens a lot. I would like something comparable for my Canon - since my Nikon will not autofocus on the Canon. Is a 55-200mm comparable (because of the focal length difference)? Are Quantaray or Sigma OK brands? I have had no problems with my Nikon lenses - I don't know much about Canon brand lenses. Thanks

No personal experience with SLRs but here's what I know:

First off - to find the equivalent FOV on a Canon digital SLR, multiply the focal length by 1.6 .. so a 55-200 would be something like 88-320.

Second .. from all I've read Sigma is a quality brand .. they make several lenses that rival Canon and Nikon's top lenses. However, the only advice i've seen regarding Quantaray is to stay far far away.

For lens info ... you could check out PhotoZone (http://www.photozone.de) and FredMiranda (http://www.fredmiranda.com), they have a bunch of lens reviews and ratings.

If you want a consumer 55-200 then the Sigma 55-200 4-5.6 is a VERY good value for money option... you should be surprised at the quality for the price....


If you want a high quality, bright zoom then the Sigma 70-200 f2.8 is a great lens also.... Obviously a fair bit more expensive....

Two good and reasonably priced tele-zooms for you:
Canon 75-300 IS USM
Sigma 70-300 APO Super II

The only caution I would give is that QC can be shakey at times for 3rd party lenses so either buy at a retail store where you can test the lens or make sure the estore has a good return policy. For whatever reason, Sigma has a problem with maintaining compatibility with their lens chips and new camera bodies. I had the problem on my old Nikon film bodies. Several have reported the same problem (although now they will re-chip their lenses as long as it is still the current model - if too old, it's become a paper weight). The Sigma 24-70 f2.8 had 20d owners returning the lens until Sigma came up with a chip upgrade while the lens worked fine on the rebel. You are guaranteed forward compatibility with a Canon lens (as long as they keep the EF mount).

A lot has to do with your price range. General questions without either usage information or price range make way too difficult to make suggestions that pertain you how you will use the lens or fit your budget.

Canon's 70-200 f4 L lens is great ($550). If you need lower light capability, the f2.8 version is incredible ($1100). No one makes a really good wide to long zoom lens - apparently it's beyond today's technical capability but they do make some decent ones. The Tamron has gotten some good reviews and I've never heard of them having chip issues going to a new body.

If you pay $780 for a Sigma 70-200 f2.8, you might want to know that when you purchase the replacement for your present Canon body, that it will work on your new body. If it doesn't, the Sigma service center will re-chip it IF your lens is compatible with whatever 70-200 Sigma is producing at that time (expect to be without that lens for 6 weeks while they re-chip). For $300 to 400 less than the equivalent Canon, it's an incredibly good deal. Having gone through this Sigma idiosyncracy of their chip not working on a newer body, I decided it wasn't worth the risk.

Let me tell you one thing about coming from a film slr to a dslr. I was very satisfied with my Canon 28-105 f3.5-4.5 and Canon 100-300 f4.5-5.6 while using film (mostly 4X6 prints with occasional 8X10s). Now that I can view my pictures at 16X20 or whatever huge size my 20d is capable of on the screen, things aren't so pretty anymore. Using exif data and histograms, you can see exactly what went wrong and I found a consistency that told me I needed to upgrade my lenses. I'm using the Tamron 28-75 f2.8 and Canon 70-200 f2.8 (non-IS) and I'm very happy with the results - I don't have to stop down to get great clarity/sharpness. Now, when a picture doesn't quite come out, it's operator error rather than a weakness in the lens (like forgetting to reset my focus from one shot to AI for moving objects and shooting in continuous mode).

"consumer" grade zooms - everything is a trade-off between price and quality of image. I can personally tell you that the Canon 28-105 f3.5-4.5 is a great lens as long as you can live within it's boundaries.

As one poster wrote, use the fred miranda and photo.net sites to see what is out there and user experiences then do a google on the lenses you find interesting for more views and prices.

I just got the sigma 70-300 macro and love it. It does great wide open for a consumer lens. I use it pretty much as an 300mm f/7.1-8
