Ruy Penalva: The built quality cannot be very good since some inner glasses are fixed with glue as shown by Roger Cicala. This could means easy dis-adjustment.

I ask my self how DP could speak of good built quality when DP did know of these pitfalls in built construction such as - industrial Josh152's glue - use in front elements?

Additionally, how DP could talk about the good environmental seal with only few hours of testing?

Where are the tests made to show good built and environmental qualities?

Ruy Penalva: Canon should think on things more affordable.

I hope all of you can afford to buy one like myself can. That is not a strong reason to not find it pricey, almost half a car price. I have enough money but I earn it honestly so... toidI

Ruy Penalva: More important than examine the IQ of this lens is to analyze its weak internal construction. Avoid it.

Read Roger Cicala description before say the above. Optical frontal elements fixed with glue!

Ruy Penalva: Sonykon?

It should state: Nikon D600 - Sony inside. Every brand do this when use a third part (core) hardware. Roger Cicala said that this sensor unusually become dirty!

You pay for a Nikon but get a Sony. Why not buy the original?

My sensation is that we are in the very beginning of video production and the industry keeps bringing innovations each year so that they do not fit in the consumer (even the pro) budget.

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.
