Bee's
With Bee populations ever declining in the UK, and being such important pollinators. I think really important to do your bit and help them on their way. We found this bee very lethargic, looking sorry for itself. So We put a little honey in a cup and added some water then used a pipette to put a drop on the floor the bee seemed to love it! Sticking its long tongue out, a few minutes later it flew off!

Blended Multiple Exposure
While this is definitely a post processing technique, I think it works very well in sports photography.
The technique I use is pretty simple if somewhat labor intensive. When shooting, a tripod is ideal, but you can handhold. You want to capture the ball (or person/object that is going to move) from beginning to end. This usually means a wider shot that normal. Then, motor drive through the action, keeping the camera still. This is a great technique to try when you are at a blowout game, or just find yourself shooting the same old thing.
Back at the computer choose a first and last photo, and stack them as layers. Blend these being careful to choose beginning and ending players as well as ball positions, with soft transitions in places where the photos are identical. Now add each frame between these two one at a time, selecting the ball with some room around it, soften edges, invert delete. (removing everything but the ball and a little of the environment around it.) If the position is a little off and the background does not match, use the arrow keys to place it in the right position.

Does this kind of AF patent already exist to improve DSLR phase detect?

Hi,
The A7RII is getting a lot of attention, especially as regards its AF ability. A lot has been said about DSLR phase detect's "moderate" ability to AF on a wide-aperture primes and AF micro-adjustments.
So, I was wondering if a patent such as the following was already reported here or elsewhere: the idea is to primary use the usual dedicated phase detect of the DSLR. Then, when mirror raises a second unit, on-sensor phase detect (Dual Pixel AF for Canon), corrects the slight inaccuracy by asserting good AF rather than predicting it just before taking the shot.
Given the fact that even if the external AF module is not accurate, it is not completely off even at f/1.4. That means the correction to be done by the on-sensor phase AF would rather be minimal, hence meaning NOT THAT MUCH time consuming.
The external AF and on-sensor AF would share the same AF points. So when the mirror raises, the on-sensor AF knows which was the selected AF point and therefore knows where the "correction" has to apply.
BTW, some DSLR already proposes a delay when the mirror raises to wait for mirror vibrations to dampen. So let's use this "idle" time to do what's described above.
The only "risk" would be that the viewfinder remains dark a bit longer. But aren't we already used to it when exposure is slower than say 1/60?
It will also correct from brand to brand variations (like Sigma not focusing as good as Canon lenses on an EOS body)
This would make wonders within the Canon AF dedicated menu where you could set a priority with a slider to the importance you allow to the "correction": from quickest (on-sensor AF deactivated) to not fire the shot until the on-sensor has 100% asserted the accuracy.
What do you think? Any reports of this?
If it doesn't exist yet, my idea first
