Please Help with 100-400 L IS

[rebel61021]

was taking pictures at a air show today and almost all the pictures are a little fuzzy don't know if it is problem with the IS or is it to slow of shutter speed becasue it is a cloudy rainy day? here is one of the pictures that is the better of the ones I took the rest are so blury that they are junk. any comments on what I should do to check this would really help me. the exif info was AV Mode, F\10 1\15sec ISO 100 at 190mm.

That lens loves light. I always change my ISO to a faster "film" speed when the conditions warrant, very often going to 400 and 800.

Yes, I agree.

Crank up the ISO so that you can get away from that 1/15 second stuff.

I would have had the camera around ISO 800, and then let the I.S. in the lens try to do its best with it.

1/15 sec. for moving objects, and with a tele? :shock:
Don't blame the IS, it can't help! ;)

f10 on a cloudy day and low iso. Not the lens' fault ;)

A few adjustments in PSE and your picture really is quite impressive considering you only used 15th sec and a focal length of 190mm.

Methink that everything has already been told, but I'll chime in trying to summarize:

Too slow shutter speeed for the focal lenght: you have one of the finest IS of the world, but @1/15 and about 200 mm it can't help too much.


Low ISO: your DR lives happily with ISO up to 400 and even above . This means that you would have recovered at least 2 stops. From 1/15 to 1/60. And at 1/60 the IS does wonders even @400 mm. forget about the 200.


F/10: shooting at full aperture would have recovered almost another 2 stops. That 1/16 would then have been (total 4 stops between ISO and f/stop) 1/250.
Honestly, considering the conditions, I see a GREAT picture. Cannot blame the lens at all. It is a lens that even in those conditions (low ISO, slow shutter, too close, on a cloudy/rainy day) have done absolurtely wonders. Thry that with other lenses and then you'll see what is a really disappointing picture. :D



Give it another try, possibly in better conditions, and you'll be amazed. This is what the 100-400 can do at full aperture and 400mm (exif included and not cropped od postprocessed beside size for posting)... Don't blame the lens and have a lot of fun with it. :) :)

Hope it helps.

Edit to add: I forgot to mention the fact that you need some sensor cleaning ;)

Thank you I was hoping it was me and not the lens now I know. guess I have lots to learn yet. I just wished we would have had a better day for the show.

We all have to learn every day, don't worry. As for the weather well.. for that you have to talk with The Guy In The Penthouse, we can't help :)
