On CP+ 2015 Sigma Interview article (88 comments in total)

Wish Sigma made the 120-300mm F2.8 Sport available for Sony A-mount...

Why Sony doesn't implement the AF/MF switch operation on every lens just like the Macro 90mm lens? And why the Zeiss 35/1.4 has an aperture ring but the Zeiss 55/1.8 and 35/2.8 don't?

You either get a distance scale, or aperture ring, or MF ring mechanical coupling but not all of them... BTW, focus-by-wire is horrible. Hope they made the Zeiss 35/1.4 with mechanical coupling.

has anyone used Nissin products? I'm interested on having radio control and at the moment I was thinking about using my HVL-F58AM/F43AM flashunits with Phottix Odin TTL...

I don't shoot m4/3 but those are some good looking lenses. At first I was like...whaAAT? green? But after looking several times at it, I think I like it.

Rooru S: Partial refund??

In the note it says they're going to perform partial refunds... but I'm quite surprised they're doing partial refunds instead of total refund.

On Sony Alpha 7S Review preview (392 comments in total)

Really enjoy taking pictures with the a7S. It's just like a mini Nikon D4S but with less weight/size, worse AF performance and way less fps in AF-C mode at a cheaper price point to compensate for all of that. I still see the D4S and 1DX as the best photography tools but the a7S is the best daily use camera when best overall performance isn't required.

Rooru S: The AF issues are only with lenses that has to move heavy elements or is it something independent from that?

maybe more powerful AF motors is the answer? It could mean it drains batteries faster, but for the sake of AF speed, I'm quite sure that's a price some are willing to pay.

Rooru S: So, the guy is Swedish, lived in England...so...why don't they offer some swedish museum a joint effort to keep the album in good shape and take turns to exhibit it or make it available for researchers and students?

hmmm you're right...if Sweden really wanted to have such album, they would have pledged for it

bluevellet: Just don't send the album to Mosul Iraq

Seeing ISIS going through that museum smashing 3000 year old artifacts with sledgehammers... Just awful.

More awful is what they're planning to do with the world. But yeah, I get your feelings about the matter.

Tapper123: Smallest size is 77mm? How about smaller sizes for mirrorless camera lenses too?

For the minimum filter size (and the price), it's obvious they're aiming for users of big and expensive lenses from Nikon and Canon.

Frank_BR: Wouldn't a deep plastic hood be simpler, cheaper, more effective?

I'm here thinking amd wondering if your solution applies to wide-angle lenses.

Rooru S: BCN rankings has been published for last year results.

SLR sales
Canon 54.7%
Nikon 39.1%
Ricoh (Pentax) 4.5%
-------------------------
54.7+39.1+4.5 = 98.3%

Guess Sony only managed to get 1.7% of A-mount equipment... Maybe the next thing in the spin off crazyness is Sony A-mount.

EDIT: Actually that's a great Idea. Sony should sell A-mount and let another company keep developing lenses and bodies.

They managed to grab third spot in 2013 with 7% of overall sales of DSLRs in Japan (I suspect people started taking Sony seriously that year after the a99 was released) so they were in a good direction and Sony already had a good global market share when they made the a700, a900 and specially, the a850...but then, also in 2013, eveything changed when FE cameras were released and Sony decided to put A-mount aside.

I wouldn't say A-mount development was a waste of resources. In early 2013 it was a good idea to keep making A-mount since it seemed they had a good plan to develop high-end stuff, but not anymore. 3rd party manufacturers (expect Tamron) aren't interested in Sony that much and Sony isn't doing that great with investors pushing Sony CEO to spin off some divisions and selling others.

On FAA proposes regulations for commercial drone usage article (115 comments in total)

Great! As a fixed-wing pilot myself, I can't remember how many times I have heard from colleagues that have found themselves meters away from hitting a drone.

There are some recreational parks nearby a local airport and obviously, people want to test/show off their drones...nothing wrong with that, but they do it on the landing flightpath.

If the FAA approves this, then in no time, local authorities on several countries will copy and adopt the regulations. But authorities have to provide maps for drone operators to know where they can fly drones, how high and have a notion of the restricted, prohibited airspaces (including airspace around airports)

A year ago, Mobile Phones were considered one of three Core/focus for Sony...now they're thinking about selling it. Wondering what will come next.

Rooru S: Here here DPReview Team. Arrange a test where there is some sort of vehicle moving towards the photographer at a constant speed.

Have the ILCA-77M2 with the SAL70200G or SAL70200G2 set at F4 and the ILCE-6000 with the SEL70200G set wide open at F4 (or both at F5.6).

Take a series of photos, two passes of the vehicle on each direction per camera to have an average and see which one performs better with a combination of Z-axis and X-axis tracking. There you have a joint A77M2 and A6000 AF review and you can finish your A77M2 review that has been long overdue (quite surprised there ir a review for the 7Dmk.2 but none for the A77Mk.2)

If you're not going to do it...maybe the TCS TV can do it for us...

Yes, you're right, what most people want is a camera capable of predict the unpredictable. But right now the excuse of Dpreview for not doing a A77M2 review is because they don't have a proper method of testing AF.

Well my method is a good start and they can update their review like they do with other camera brands and while they're testing the AF, they can do a A6000 vs A77M2 showdown. They can also do a circuit where they have some driver drive a small circuit.
