Great shots from all.  I also just returned from a stint in BC and the Alberta rockies.  Finally made it into Wells Gray provincial park.  The Helmcken falls are over 450 feet high and about 75 feet wide, maybe the highest in North America.  The sun was my enemy.  The first shot is from the viewing side the second from the opposite cliff as I forced myself up to the edge - looking straight down to the water.  You can see the viewing platform in the last shot.

6D with 24-70 F4

Another example of 6D AF.  ;) Center of course.

The window was open and the guy had his p&s camera trying to get a long shot when this happened.

Love all the recent shots.  I have nothing, not a good summer but I'm heading out to BC, my neighbor province for about 3 weeks and am hoping for ...... anything will be better than here with my pet nuthatches and blue jays and chickadees! ;)

I agree, let's keep it more light-hearted and less competitive and mainly about birds.

"But there is a definite level of diminishing returns as you go higher up the chain."

Very true and something I learned in forking out $7k of my inheritance on the 300 2.8 II which I compared carefully to the Nikon AF 70-300 I owned.  I see both points of view and the validity of various comments on either side but if you can't justify the $$$ it's a no brainer - enjoy the less expensive gear cause it's still very good. 

Just be careful to not say overly critical things about the high level stuff or folk will get ruffled, but not me.  I do what I like and you do what you like and we still have free speech for now at least.  Heaven help us when the crazys take over.

Just to mention that my set is Kenko and I don't allow them to carry the weight of a lens or use multi-stack with the 300 or 300 X2 (too much play).  Was a great deal on Amazon last year so about $150 for the set (about 1/2 local store price), no regrets.

Another uncropped, ISO 1600 dull day.  300 with 36 ext.  DOF is a real challenge.

Here's Downy with 300 and 36 mm ext.  No cropping.  Set-up from a blind, maybe 5 feet.  Not sure if I really needed the tube for this shot but I had been in closer.  Data is included in the shot.  Everything is automatic and focus is fast.

I love the 300 with and without tubes for butterflies - near macro at a distance.

Coldhands it's rain for you now instead of snow I guess.  Nice shot.  Reminds me of last winter after trudging around in the snow commenting to myself that there was nothing to shot.  Guess there always is if one is truly watchful and selective, but acreas of snowy fields are challenging. ;)

Last Feb was one of those days!

Photography Technique / Re: Intentional "wrong" afma for creative backfocus?
« on: September 04, 2014, 03:44:12 AM »
Here's a sample of what I run into fairly commonly with birds.  The 6D algorithm will pick up on the sharpest features in the region of the eye and for many birds when the DOF is shallow that leaves the eye slightly out of focus.  This is where I may choose a slight backfocus.

This was a vertical shot using the spot upper focus point on the eye.

Phew, I can barely follow all the technical stuff in these CR threads but what seems to be clear to me is that the economics and market determine an awful lot more than we tend to realize and it's not all about who has the superior technology.  Perhaps not unlike a board game with players carefully choosing their moves for fear they will find themselves trapped!

Jon,

"DPAF, even if it gets that sensitivity boost their latest DPAF patent describes, just doesn't interest me enough to matter yet. I don't think it's a viable replacement for PDAF, and won't be for a while still."

I thought the 70D used DPAF in a two pixel phase detect format (PDAF), so could you please clarify.  Apparently, the dual pixels covering most of the sensor can function as selectable AF points.  What's holding this technology back relative to the anticipated 7D2?  It's really hard to believe the 7D2 will actually be a ho hum camera.

Thanks Jon, great comments as usual.
