Evening all,

Quick question to those using or have used the IS (image stabilized) EFS 18-55 Lens on the popular T2I; Does it work?

With the IS housed in the lens I'm guessing it's a mechanical function and with our sometimes high freq vibes I almost imagine that instead of stabilizing the image it too would eventually vibrate. Jello? I don't know. If anyone has any experience with this lens I would enjoy hearing what your thoughs are on it.

Thanks, goodnight.

It's a good lens with fine image quality but not really wide enough for low level AP in my opinion. You'll want to be around 12-15mm most of the time. A Canon 10-22 is perfect!

+1 for the canon 10-22mm f3.5/4.5 for around $800 new

The tokina 11-16mm f2.8 for around $650 new is not a bad choice either...depending on the camera of course...

Great advice. Thanks guys. I'll look into those lenses.

Craneman · 09-08-2011, 09:53 AM

I have a Sigma 10-20, it's cheaper than the Canon and very nice in my opinion.

mbrashear · 09-12-2011, 08:01 PM

Tamron? Good, ok or no?

what would you suggest for the 550 for aerial videoS??

Thank you!

For those of you shooting with the Sigma 10-20 and Canon 10-22 are you shooting near the 10mm range?

It seems like anything wide with barrel distortion around the edges will be magnitudes harder to stabilize and get looking good in post. Are you guys correcting for distortion before stabilizing (loosing even more resolution)?

I like the Sigma 20mm prime. I've had problems with distortion on the Sigma 10-20, the Canon 10-22 and the Canon 14 f/2.8 on the T2i.

yeehaanow · 09-14-2011, 01:25 PM

I have definitely had problems smoothing out anything bumpy with the sigma 10-20mm when below ~17mm. And even still at 17 and above sometimes, which is where I always shoot now. If there's vibration and that slow wavy jello at 10mm, forget it.
I was thinking the canon 10-22 would be better but it seems like it's not.
My favorite lens for wides is the canon 16-35L. $$$$ and it's heavy but to my eye has the least barrel distortion. Never tried it on the heli before though.

10mm on the Canon is too wide, never use it there. Most of time around 16-17. The further you are from subject, the more you can can get away with wide angle without it looking too distorted. If you have close shots...even 16 range can give too much distortion. Nice lens, I've used mine for about 5-6 years now.

mbrashear · 09-14-2011, 09:53 PM

Can anyone post up some good examples of some side by side examples or just good examples of distortion using a 10-22 lens?

onlocation · 09-14-2011, 10:24 PM

You can find a ton of them by using googles image search feature.

Hi Craneman,
Nice heli as your profile picture. Is it your heli, or just a stock photo?
I love the colour and so thought I would ask.
thanks

mbrashear · 09-15-2011, 06:17 AM

Thx for the example and I will do a google search for more.

is this what you use; Sigma EX DG Aspherical RF 20 mm F/1.8?

mbrashear · 09-15-2011, 07:54 AM

onlocation ,

I cannot seem to find for the life of me a sig 20mm prime. Ive checked the sigma website with no luck. Sorry to ask you to hold my hand in this but can you point me in the right direction?

buhojean · 09-15-2011, 10:55 AM

This is my video with the sigma 10-20 in action

[ame]http://www.youtube.com/watch?v=i_gz_sa028o[/ame]

Sometime in 10, 12 or 14, on the 7d.
Is very good lens.

tott · 09-15-2011, 01:14 PM

Just something to keep in mind while you are searching for lens and lens distortions.

Just remember with ANY zoom lens you are going to get unwanted effects at both "extreme" ends of the focal range. This is the inherent nature of any zoom lens. A prime lens is great because you do not have that sliding scale of a "sweet spot" but they are limited to what they can shoot. With ANY zoom lens you will have a much better picture if you do not go to the ends of the focal range on either side. So for a canon 10-22mm lens you would stay within the 14-18mm range for the safest range. Depending on your subject you can "slide / expand" this range to find the extremes that will work for that shoot. This is easily done for changing shoots when you have the lens in your hand but not so easy when it is on a RC platform.

The 14-18mm range is just for explanatory purposes and NOT a scientific number range for that particular lens. It was only to show an example of what I was explaining.

If you look at the lens distortion for any given lens and then compare the entire zoom range you will see what I am talking about......again.....google is your friend here....

I hope that helps...

JASON

Beautiful footage, the scenery was nice too.

Tott,
Thank you for putting it so that a novice as myself can simply understand what is, I'm sure, a rather in-depth and complicated facet of this art.

R_Lefebvre · 09-23-2011, 04:15 PM

I've got a quesiton... maybe a newbie question but...

I have a Canon Rebel XT, APS-C sensor with the 1.6 crop factor. If I use a wide angle lens that has barrel distortion, does the crop factor on the sensor cut out a lot of the distortion? So, if I purchased a 10mm lens that had a lot of distortion, but it would operate effectively at 16mm on my camera, the distortion would be gone?
