Canon EF glass probably isn't done just yet, but...

Shutter lag can be very significant in some cameras. While I usually shoot with dSLR, I am also known to leave it at home an rely upon the smartphone camera, when photography is not the main purpose. A few months ago, my wife and I had the duty of babysitting two grandkids when the usual daycare was not available for one day. I recall trying to use the smartphone to take a shot of the older boy (4.5 yr.) as he went around a not-large, not-fast merry-go-round. I could NOT get a good shot of him, due to shutter lag. And I could not anticipate the shutter lag well enough to ever get him during the short duration of one ride session!

Anticipation and knowledge of the material being shot is what separates the pro from the novice... Take any non-sports shooter or a shooter not familiar with a particular sports, and their keeper rate and quality of images won't be the same as the person that shoots that same activity often.

Just like drag racing, once you see the final light start to go out before the green light lights up, you hit the gas. Your reaction time, plus the gas pedal to the computer sensors and linkages is about 1/2 second for a good racer, and if you wait until you see the green light, your reaction times on the slips you receive will stink and people will poke fun at you. You hit the gas (or shutter) just before the action happens that you are very sure will happen based on your experience of what you are shooting. Took me about 5-8 tries at the box to get this down, it was a bit difficult, sometimes I would red light, sometimes my slip times were bad.

However it doesn't affect your quarter mile times, your timer for that doesn't start until your front wheel breaks the first sensor, so this analogy no longer holds here.

But still worrying about another 30-50ms of shutter lag won't matter; you will acclimate in your shooting and adjust your anticipatory actions, it will just become second nature after a few shoots.

ET is not affected by reaction time. However first across the line wins. Winner has the lowest sum of ET and reaction time, ie the package.

I haven't been on this forum or really following much of the industry in a few years, but have been shooting, with a Canon 5DIII and a collection of EF glass. I just re-registered here and saw this thread. What's the story on EF mounts right now? Are they actually being discontinued?

No, Canon has officially stated they are currently on hold with EF lenses because a) the collection is already so very mature, there aren't too many holes in the lineup, b) they are concentrating on R bodies and RF lenses right now to get those up to a good set of lenses for mirrorless owners, and c) they are listening to consumer requests and if there is demand for EF tech, bodies or lenses, they might plan new products in the future.

Anything beyond this is speculation, but one can make educated guesses on where this will go.

Ok, thanks! Surely at least the EF line up will stay viable. There are some fabulous lenses there. I have 2 of the latest tilt shifts and you don't see many lenses like that. Once I started using them, I can't go back to standard lenses for many types of shots. The big white primes are another group that seem like they are quite viable.
