Canon 28-300 F3.5-5.6L Is USM

Tue Apr 18, 2006 2:57 am

Hi all,

I am contemplating the purchase of this interesting lens.
The main reason is to eliminate the need to constantly switch lenses when moving from location to location and collecting dust spots.
Just wondering if anyone is using it for aviation or other photography and their opinions of it.
Thanks!

Cheers,
Kaz

Hi Kaz,
I love this lens. You don't have to swich lenses all the time and you have great pictures. But don't forget that it's a heavy one. Just watch my pictures here on A.net.
greetings,
Wim

Wim,

Excellent photos! I've heard that the push pull is a dust-magnet. What has been your experience?

Cheers,
Kaz

I have the 100-400 for 2.5 years now, no dust problem at all. Basically all zoomlenses (except shorter focal length zooms) have bits going in and out. The push-pull design allows very fast zooming, but will that cause it to act as a pump? I have not encountered that...

I think the dust problem only comes into play when the rear element moves alowing air from the lens to circulate into the body.

Ok... I thought the question was about dust inside the lens, not on the sensor. The sensor gets dirty anyway, no matter which lens you use.  Smile

Hi Kaz,

I also happen to be a happy owner of the 28-300L as well as the 100-400L.
The dust problem is very little to none as far as I can tell from the amount of spots I can find when enhancing contrast to eliminate them in PS.

The image quality of both is excellent.
I tend to use the 28-300 from 50 mm and above. At 28mm it is better to stop down a bit to lets say F/8 - F/11 to boost sharpness a bit.
From 50-300mm its sharpness is great! From 28-50 it performs like the normal grade wide-angle EF lenses.

Also the IS on this lens is much much better than on the 100-400.

Just check my pics in the DB. A lot of them were shot with the 28-300.

rgds,

Jeroen

Thanks for all the info everybody.
Now I just have to find out which place sells it the cheapest.  Smile
