Miah,  I think this is a very decent shot.  You had the eye in focus and sharp.  Congrats.

You have a 5D3, which is an awesome camera with excellent AF capabilities.  This is what I would do if I were you.

1. Flock of birds: 61-point AF in AI Servo, AV in f8 or f11, Evaluative Metering, add light by 1/3 to 1EV with exposure compensation depending on how early morning/soft light, check the histogram to ensure that you have some data in the most right hand box but be careful not to over-expose the highlights, adjust ISO to get shutter speed above 1/2000 sec (you can go lower but 1/2000 is a good start).  A properly exposed image on the 5D3 should have very little noise at ISO 1600.  Even at ISO 3200, noise can be reduced at post processing.

2. Individual bird, same as above but switch to AF center point or center point expand with 4 or 8 surround points.  My favorite is the center point expand with 8 surround points.  You may have to add 1 EV or more in the early morning or if you have a lot of bright sky in the frame.

attached is an example of an osprey taken with a 1DX, canon 500mmf4, 1.4X TC (total focal length = 700mm), f5.6, Evaluative metering, +2EV exposure compensation, ISO 1000, shutter speed 1/2000, AF AI Servo, center point expand with 8 surround point.  At this speed, you can stop most anything.

Good luck.

Lenses / Re: Kenko TC and AF at F8
« on: October 14, 2012, 07:27:22 PM »
After reading Authur Morris blog, I went for the Kenko 1.4 Teleplus for use with my 70-300L f4-5.6 and Canon 5D3.  I'm happy to report that the 5D3 retains all 61 points AF.  The AF at F8 isn't bad at all and the IQ is useable.  I have also a 300F2.8 + 1.4X and 2X, but for a walk around lens, the 70-300L is much lighter and the Kenko 1.4X does a pretty good job.  Will test some more in the weeks to come.  The attached photos are shot at 1/2500, f8, ISO 1250, 420mm.  The focus is spot on as in the second photo.

Lenses / Re: Canon 200mm 2.8 l ii: what's the deal
« on: October 01, 2012, 09:27:44 PM »
I traded the 200f2.8 II for a 70-300L and don't regret it.  The lens is pretty sharp under good light, but under low light, I found it was tough without IS, so the non IS negated the f2.8 for me.  It's very light. Which is great or carrying around.  I found, however, because it's so light, I kept forgetting that it is a 200mm lens and so etimes got blurry picture.  I'm pretty happy itch my 70-300L under good light and appreciate the extra reach in a small light weight package.

I'm new to photography and I started out with a T3i and Canon 100-400mm back in November 2011.  I shoot mainly wildlife: wolves, bears, birds, and whatever that moves.  I could get sharp images up to 300mm, but couldn't seem to get equally sharp images at 400mm with the 100-400mm.  I bought a 300mm f2.8 IS Mark I, a 1.4X II and a 2.0 II TCs, and a 5D3 in April 2012.   I saw my photo quality improved dramatically with the new equipment.  The T3i + 100-400mm cost me about $2,200, the 5D3 + 300mm f2.8 (used) + 1.4X Tc + 2X TC ~ $7500.  I'd say I got my money worth > 3X improvements :)

However, now that I know I can take sharp images, I suspect I can go back to the T3i and 100-400mm and get much better quality images than I used to, so may be not 3X improvements :(.  But I enjoy photography a lot more and have no regret for spending that kind of money on new gear :)

Lenses / Canon500mm f4 IS II - should I order from Camera Canada
« on: August 26, 2012, 04:39:57 PM »
Camera Canada lists the canon 500mm f4 IS II at $8,999 vs others at $10,999, will accept pre-order.  Has anyone bought high end equipment from this merchant before?  Is the lens under warranty by Canon?

Lenses / Re: 500mm f/4.5 focusing help?!?!?
« on: August 17, 2012, 12:53:54 AM »
The 5D3 has excellent image quality at high ISO.  I regularly shoot at ISO 1000 so that my shutter speed is above 1/2000.  If your feeder is sharp and the bird itself is blur, I would think the shutter speed is too low or your AF is off.  How did you set the AF?  Try Focus priority instead of shutter release priority and shoot at F8 instead of wide open at f4.5.

Lenses / Re: 70-300L or 70-200 2.8 IS II?
« on: August 14, 2012, 04:18:11 PM »
I have the 70-300L and love it, very sharp, light weight, IS is great.  Not a bad lens even indoor when paired with the 5D3. You can bump the ISO up a stop or so to compensate for the smaller aperture (I think it is F5 at 200mm) and the IS allows you to shoot at reasonably low speed.  and it is shorter (when retracted) and cheaper too.  The draw back is it does not accept the TCs whereas you can add TCs on the 70-200 to reach up to 400mm.

43
The 100-400 is not that sharp at 400mm, so adding TCs and losing 1 or 2 stops will hurt.  But I have seen people claiming that the 100-400 with the Kenko 1.4x is very useable in good light.  You just need to check it out yourself I guess.

44
here is a BIF shot of a black skimmer with 5d3, 300 f2.8 I IS, 2X II, 1/1600, f11, ISO 1000, cropped (forgot how much), handheld.  Its useable for sure, but the AF is slow and you need to give it time to acquire focus.  once focus is acquired, tracking seems fine.

45
I had the 100-400 in the past but sold it to get the 300 f2.8.  The AF of the 300 f2.8 is superb.  Adding 1.4x is no issue either.  Yes, cropping is just a fact of life for BIF at 400 mm even with a cropped sensor.  The 300f2.8 plus 1.4x is very sharp even at 100 percent.
