:?I use to have a Canon 300mm lens for my Canon T90. [have since sold everything thats non-digital]Since purchasing my DSLR 300D I have a 28mm-85mm and a 135mm. For wildlife photography I am considering purchasing Canons EF 300mm f/4L IS USM lens. This sucker comes at a heavy price. [$1140] Do you think that this is too much lens for my300D? However, I do like the stabilizer feature. Would rather shoot without a tripod since many wildlife opportunities just don't wait aound until you get all set up.

For a Canon prime tele lens setup around 300mm and around $1000-$1500, you have two options. One is the 300 f/4L ISand the other is the 400 f/5.6L.

If you go with the 300, you can easily hand shoot in decent to (relatively) poor lignthing because of the IS, and you can also add the 1.4 teleconverter to give you 420mm f/5.6 with IS which bests the 400 f/5.6 without IS. However, the 400 in good lighting will focus and track noticably faster and arguably give you sharper images.

If you are shooting active subjects, then the IS is worthless because you are going to want to shoot at a high shutter speed (1/1000 sec or so) to freeze the action, and at that speed, camera shake from hand shooting is not a factor.

I've used both andended up usingthe 300a lotmore because of both the IS and a faster f-stop, but again, in good lighting and especially shooting moving subjects, the 400 can't be beat (at that price)

I'm sure others can comment on Sigma lenses

And about buying a lens thats "too much" for your Rebel, forget it, a good lens will still be a good lens when its finally time to replace an obsolete camera body (probably many times over).

:-DThanks tjk3052 for the feedback. Been leaning towards the 300 and adding a 1.4 converter to my equipment.

I guess that I should have asked if the EF 100-400mm F/4.5-5.6L IS USM would be a better choce than EF 300mm f/4L IS USM ?

Something I forgot to mention isthat if you want to use a 1.4x teleconverter with the 400 or the 100-400 (at least near the longer range), you will lose autofocus. You will not with the 300 (although focus might be a little slower).


Read this, it sums up your dilema perfectly. Itcompares the 300, 400, and 100-400.

If you can afford it have a look at the Sigma 120-300 EX F/2.8.You don't get IS but at F/2.8 you dont really need it.Also you can use a 1.4x for 168-420 at F/4 or 2x for 240-600 at F/5.6. Cheaper then the Canonand half the price of the 120-300 you can have a look at the Sigma 100-300 EX F/4 which i believe was delivered from the 300m prime sigma.

Well I sprung for the Canon EF300mm F/4.0 IS USM lens which I received in the mail yesterday. Ran down to the local park this morning to try it out. Took about 40 pictures of very thing from swans, geese, ducks coots,heronsand some otherstrangle looking water fowl. Had a back up battery along not sure how much juice that big lens would use. When I got home opened the card door to remove same & :angry:dummy me I had left the card in my ScanDisk reader. Well tomorrow morning will do it all over again. Have you ever done anything that stupid?
