On Sigma 50mm F1.4 DG HSM | Art Lab Test Review preview (557 comments in total)

The price of the lens in Side by Side comparison is wrong.

Lan: In other news, Sony also announced Europe falling off the face of the planet ;)

What about 50p?

I think it can both NTSC and PAL along with 24P. It is described in Sony hot-site.

The sensor reads out image data from every pixel, even during Full HD and 4K*2 movie output, and enables recording and output of Full HD movies at 60p (50p), 60i (50i), 30p (25p) and 24p frame rates, as well as output of 4K movies at a 30p or 24p frame rate, with both resolutions available at both full-frame and APS-C (Super 35mm equivalent) size.

Very practical. Is it a filter or a curtain? Probably Fred of Flintstones will adopt it.

On Preview:canon-eos-70d (1311 comments in total)

What do you mean by:
"Canon has made no fewer than 156 EF lens models in the 26 years since the EOS system first appeared, and it says that 103 of them fully support Dual Pixel CMOS AF, including all current lenses"

This Dual Pixel support means continuous video focus in those 103 lenses?

Why not one like that to a full frame sensor?

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.
