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...

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 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

Canon should think in things more affordable.

Sheet. I will remain on the ground.

Seems to be Aedes aegypti the Dengue vector.

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

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

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!

Sonykon?

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.

Stone made.

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...

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

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...

Best late than never.
