I wonder if they assembled the front element with glue as in the 24-70 f/2.8 VC as reported by Roger Cicala? http://www.lensrentals.com/blog/2012/09/tamron-24-70-f2-8-vc-issue.

Ruy Penalva: I think a better comparison would made in video mode or moving stills.

Does the smaller G5 sensor play a role in that focus readiness advantage? Could the combination of phase and contrast detected be responsible for that lag since it primarily aim at video capabilities than at still and is a plus in the still mode? A comparison with Canon new mirrorless should clarify part of this.

As the glitch could be solved via firmware it seems caused but some malfunction in the camera-stepper motor feed back. The battery and lens removal confirm that. Could that occur in 18-135 STM lens too? To how many cameras bodies will Canon address the fix?

Octane: Awesome that a manufacturer spends a lot of time and effort to make an 'old' camera much better and provides it as a free upgrade via software. I hope this will set an example!

Best late than never.

Only new images can be re-dimensioned and rated. My jpeg old images were not accepted. Old raw files cannot be processed too.

That is in accordance with the Olympic Games fair play. If you pay attention every DSLR is a mirrorless camera in video mode.

Hard to believe. No shaking. Was the cell phone in a tripod? The song seems to be edited too.

On Canon issues allergy warning for EOS 650D/Rebel 4Ti news story (176 comments in total)

Canon would do better if it explain the chemical reaction that produce this by product from the rubber accelerator. Humidity and high temperature all affect the life span of any rubber but we were not told from what kind of substances that rubber accelerator is made. Hands are (but its nature) very resistant to allergies and I suppose that the out of the range pH of the substance (acid or alkaline) is the cause of the injuries, chiefly in the eyes, and not a true "allergic" reaction.

Too much edition makes the photo a photocrop made by Photoshop. Do we need a good camera and lens?

On Canon significantly improves EOS 7D with firmware v2 news story (296 comments in total)
In reply to:

Ruy Penalva: Good news. I wish it could also have several raw files options (small, medium large) like 5DMKIII. Shooting so fast it can be placed as a photojournalism camera. The GPS module will help me tag photos abroad and abandon my GPS. I think Canon should add several in camera processing 5DMKIII has, including HDR.

My fault, thank you, I have never noted that!

Denton Taylor: Phenomenon? lol. Used to be called BUGS.

Phenomenon is a Latin word and means something "unexpected":

a : a fact or event in the changing and perceptible forms as distinguished from the permanent essences of things: as (1) : a mutable, caused, or developing aspect of things as contrasted with their fixed and substantial natures (2) : a perceptible aspect or appearance of things as contrasted with their true or ideal being (3) : an object of sense perception as distinguished from an ultimate reality (4)

To tell you the truth all DSLR in video mode is a mirrorless camera so is meaningless to say that Canon does not have a mirrorless camera!!! DSLR with video capability is an hybrid camera with or without mirror.
