Canon 100-400mm Is At Airshows

Thu Jun 30, 2005 1:40 am


I have just brought the Canon 100-400mm IS lens, and I since a lot of you in this forum has this lens, I was hoping you could answer some of my questions about using this lens at an airshow.

1) When do you use the IS?
Do you always have it on in Mode 2, or only for takeoffs and landings and turned off during the display routine, or do you keep it turned off at all times?

2) How does the IS affect battery use?

Thanks in advance.

I leave IS on in Mode 2 all the time, except when using a tripod. It has no noticeable effect on battery life.

Mode One is for still photography. Mode two is for panning. There is a considerable difference with IS than without IS so keep it on if you can. The batt. issue I haven't really noticed as I have the grip.

Well i use IS on all my lenses and have noticed no issues withbattery life at all.
I also use the grip on my 20D and get around a full day out of a pair of batteries which will get me 2000-2500 shots.
Like everyone else mode 2 works well at airshows.

I always leave it on. I have not noticed a significant reduction in batt life although maybe there is a slight reduction.

Personally, I have not gotten the most out of this lens.....yet. I think it may be me, my skill in shooting steady and using the correct settings. I do have a lot of good pictures, but haven't gotten the "money shot" yet, such as Darren's shot above.
