On article Canon unveils stabilized EF 85mm F1.4L lens (521 comments in total)

Tilt and shift are boring and perhaps unnecessary tripod lens. I had a 17mm and to control exposition was not easy. Maybe with live view, Sometimes you take a frame and see another completely different.

Nikon should hire designers for its cameras. All seem horrible. They seem like a russian Zenith.

Ruy Penalva: Is it a kind of "nikonsonyzation"?

Yes I know. But this sensor probably is made by Sony and maybe is brother of a7rii sensor. The non articulated screen also remember Sony full frame. Today, in the scale economy, sometimes is cheaper to buy than produce certain components. No problem with this.

On article Canon EF 35mm F2 IS USM gallery (152 comments in total)

I think that image samples is not the best approach to evaluate a lens. The great advantages of this one is stabilization and price, although it could be cheaper.

I always found Corel very non intuitive and hard to master. Complicated the old interfaces.

On article Astrophotography with the Sigma 14mm F1.8 Art lens (78 comments in total)

I praise it be good for astrophotography at f/1.8 because in Ciccala tests it not show outstanding MTF performance as compared with its peers.

Sigma learned the way to increase its lens price. But in South America the price use to be very much lower than that of USA.

In reply to:

Carl: The Sony 12-24/4 is produced in China, while the equivalent Sigma is produced in Japan. Doesn't this mean lower production costs for Sony? Why does this not reflect in a lower customer price?

Or, by the way, reply!
