rrccad: The A6xxx series is sony's most successful camera system by far.

and is probably the only camera system made by sony that keeps canon or nikon up at night.

@rrccad "if you look on amazon.. A6xxxx bodies are always near the top of ILC's sold. A7 series.. not so much."

I'm speculating for sure but I don't think the A7 sales numbers on Amazon represent much since A6XXX is more of a prosumer camera than A7. A7 purchasers will probably be buying elsewhere. Just a guess.

I just keep reading stories about pro photographers who have left their Canikon gear in favor of the Sony A7's.

*note: I am a Canon FF user so all of it matters little to me.

The A7 series may not keep Canikon up at night but it has taken away a LOT of sales from both those camps. I know you don't see the A7 at the Olympics but many landscape and studio Pros, etc have switched.

Neez: Look at all the youtube videos of the current state of Rio leading up to the olympics. The cops aren't being paid and crime is through the roof, even for non-tourists. They really shouldn't have had an olympics there this year, it should have been diverted to somewhere else that's not going through financial ruin at the moment.

The problem is the Olympics are a 7 year planning ordeal and 7 years ago things were much, much different in Brasil. The oil crash has crushed them (and even more so Venezuela).

This will be even easier to use once Android apps are available to use with Chrome later this fall.

Open toed sandals are a no-no going into that mess.

sherman_levine: For my FZ1000, the ISO 100 / Raw / Bulb / F:8(the narrowest FZ1000 aperture) combination washes out too many of the brighter trails. I find that adding a 3-5 stop ND filter gives me much more latitude for color recovery

Sherm

Great shots Sherm. The only nitpik is the sensor noise as has already been mentioned. It's not horrible, but it does detract. Thanks for the mention of the ND filter. I might try shooting a session with my 4 stop this summer.

Irakly Shanidze: Simply "moving away" is not going to produce adequate results in getting city skyline, just like in the example here. The idea here is to get the skyline exposed well enough to get at least 1/3 of the attention, giving the rest two thirds to the fireworks.

The trick is to expose it for long enough to make the sky blue. Do not worry about overexposure, as the fireworks are moving, and all you get is longer traces. What you get in return is perfectly exposed fireworks and the city skyline against the lighter toned sky. Below is the example.

Irakly; while it is nice to have some color in the sky for sure, you cannot push it as much as you have in your example. That is way overexposed as was already mentioned. If the fireworks are in mid-summer then you should have about 10-15 mins of blue hour light left to capture in the image. If it's earlier or later in the year then the sky will usually be very dark by the time the fireworks start. "Typical" fireworks exposures are between 2-5 seconds to capture each burst separately. Here are my examples with some color still in the sky.

Bill Bentley: "Lenses equipped with smooth iris support are marked with asterisks."

Can someone elaborate on this please? Are these lenses then the "optimal" ones to be used with the adapter?

Thank you for the explanation cyberstudio.

starwolfy: I am a full frame user and I think this lens is very interesting.

24mm with an equivalence of a f2.8 24x36 DOF + a F1.4 light gathering capability is quite interesting for group pictures in low light for example.

I have plenty of F1.4 lenses and thin DOF is always the issue. I usually prefer to go up to F2.8 even in low light because of the DOF issue making me almost never use F1.4.

I think that background blurring capabilities of bright lenses is so over rated. It ads nothing to the image but an empty blur and not context.

Then you're not buying a 1.4 lens. An inexpensive 4-5.6 prime or zoom will add PLENTY of background context. As always one needs to choose the right tool for the job. And when a 1.4 is used for the proper job (i.e portraiture) it's a thing of beauty.

EthanP99: The new sony handicam x ray camcorder?

I still have my 8mm version in storage downstairs somewhere in case anyone is interested in buying it. :-) The night vision was cool for about 30 seconds. Good thing the camera took reasonable quality regular video too.

In reply to:

DualSystemGuy: So, the takeaway is that the 2-year old A6000 still has a better viewfinder, AF, and sensor? That about sums it up I guess haha.

Because Sony as a company is annoying.

armandino: Most of the pics could be shot at 1/2 of the shutter speed in my opinion, if not slower.

For the concert ones, no. For the rest, absolutely.

On article Sweet spot: Panasonic Lumix DMC-GX85 real-world samples (115 comments in total)

Not bad. In comparing images 19/20 with 39/40 it looks like very good shadow recovery can be had up to +75 in LR before noise takes over. The dark corners in the OOC images look essentially black before being edited.

kbryd: It is the software that is the problem. These models will be forgotten by Asus after 8 months, which means no new Android OS updates, no security updates etc.

This is true and Google is considering steps to help rectify it.

In reply to:

Joerg V: I am torn between "wow" and "weird".

The final image is mesmerizing but my brain (trained to find the best focussing distance to get the best perceived overall sharpness) screams "does not compute".

Yup. The foreground cacti are far too bright in relation to the sun. I realize the photographer wanted to "highlight" this area of the image since the sharp needles look cool, but it's about 50% overdone imo.

I wonder how hot the smartphone gets while using this. I bought the Knox Labs cardboard VR box a while back and you could almost fry an egg on the phone (Nexus 5) after about 5 minutes of viewing.

zeratulmrye: Hmm... After reading this post I got the feeling that a 600mm equivalent lens is quite useless for landscapes, you just couldn't get a shot with good clarity and details because of the atmospheric distortion.

@stereo. LOL, Well, maybe not on my belly, but down on one knee is okay. :-)

I should also mention I have the f4-5.6 IS version. It's not that much of a monster.
