On article Woof! Sony a6500 sample images are here (364 comments in total)

Thank you for sharing the photographs. I wonder in the two days of shooting what was the percentage "lost" shots i.e. improperly focused? Were there any common denominators such as low light, rapidly moving subject away or towards the camera? Did certain Sony lenses focus "better" than the others? Hopefully the answers will be part of the final write up on the camera. Also thank you to Sony for supporting another product demo event for the folks who evaluate cameras.

Interesting reading. But kind of makes one wonder about the Apple management trade off reasoning; for example on the one hand they remove the mini head phone jack from their iPhone but retain it on their latest Pro laptop. While they removed the SD reader because the SD card stuck out, but have no problem selling the customer an expensive adapter that sticks out even further. The statement that they were surprised by the level of criticism shows a "Let them eat cake" level of corporate arrogance. While loyal die hard Apple customers will continue to defend Apple management choices (i.e. can do no wrong) and buy the latest and greatest laptop, others may elect to look elsewhere as the Apple magic dust finally wears off.

Apple engineering is innovative but their management team has always been short sighted and out of touch with their loyal customers. Apple should have included the HDMI and SD adapters with the laptop, since Apple management omitted the interfaces. Now reality is biting them once again as they in damage control mode to regain sales and prevent stock prices from dropping further. With hundreds of billions in cash reserve Apple can only recover lost "good will" by providing two interface adapters of the customer's choice with the laptop at no additional cost.

If Sony produced a camera that met everyone's expectations I suspect some folks would stop taking pictures since all their excuses for not taking perfect photographs would be gone. It is a wonder that the greats of the analog days were able to produce wonderful images with such constancy using primitive tools. Kinda of makes me wonder why with all the technical advancements in the camera gear why the number of great photographers has not increase seven fold. Could the problem be not what is in photographer's hands but what is behind the camera? If that is the case then no camera system will ever solve the problem since if we reach that point it will be the camera that is creating the image and not the photographer.

Thank you for posting your article on Canon's mirrorless product line development. Chances are Canon monitors DP website and has read the commentary, taking it to heart. Why I think this is the case is camera companies are moved by the sales figures and DP can influence sales. Canon has many new innovative technologies in the works along with the other camera companies. All we have to do as photography product consumers is vote with our wallet. Like we did buying smartphones with ever their improving camera attributes that choked off low end camera sales. Cheers.

The reasoning is faulty given that any attacker is free to walk the streets and gather human intelligence. If they fear another country like China then Google street maps will not make a difference given that China has informants with camera phones and recon satellites that have already mapped all areas of interest to at least three foot resolution. If China were to attack India they would take out the government and military within seven days not attack the millions of people at the street level. India would in the end respond with nuclear weapons and that is what everybody should fear.

My copy arrived yesterday and I have taken a few images with the lens mounted to a a7s and most of the previous posted observations are correct. The out of focus areas with out of focus highlights do exhibit football shaped artifacts. This is not out of the ordinary for most lenses of this type. Contrast and sharpness appears to be low at wide open. Color fringing is present but is correctable in post. Later, I will run a comparison to a Canon FD 50mm 1.2 with a Vizelex FD-Nex ND throttle on a a6300. Mechanically the 85mm 1.2 lens has a well dampened aperture ring, but the focusing ring has some minor "metal scrubbing" issues.

bernardf12: Sony's sensors are becoming so light-sensitive that their lab is going to suck all the photons out of the universe by accident one day. Let's hope they fix the 11 Bit lossy compression issue before then.

That is funny. I think Sony will eventually cough up a loss less raw file option and release the firmware. One thing for sure Sony is not sleeping on the job. Each generation of a the A7 series seems to widen the gap with Canon and Nikon. I think Sony has created a game changer, unfortunately a solution that could very well wipe out their own DSLR system sales. In my limited opinion the Sony DSLR lens adapter was just a means to get their current customer base to make the transition. Eventually I expect to see a select few of their DSLR lenses redesigned to the FE mount. And someday shut down the DSLR system production line altogether to support the FE/E mount production.

photomedium: For those who folks complain about the price: when is the last time a 'mark II' version of anything has come out out with a lower price than the original?

Folks always find something wrong about everything, but themselves.

straylightrun: One of the selling points for this camera from a video of a Sony interview, is the ability to map the record video button to a custom button. Why not put that in a firmware update for original a7s users?

Sony does listen to a select group of professional photographers and in the case of the a7s videographers. For example, they sent two engineers to listen to them when they released the a7rII according to Luminous landscapes. Hopefully they will do likewise with the a7sII release event. All camera manufacturers send out Beta versions to several key pro users for feedback. I would like to think if it were possible and pros stated as such, that they would include the change you mentioned in the next a7s firmware release.

Random thoughts:

It is my impression that Sony changed their image processing software to produce "better" low light performance. If that is the case and there were no processor or sensor changes, it might be possible to pass the firmware update to existing Sony a7s owners.

For sure I just missed it, but does the five axis stabilization work with all lenses? (Adapted Canon, Nikon, AF/MF etc, etc.. I hope so.)

Another impression, that the raw image files are still being compressed, but that Sony is considering no compression option, with some degraded camera performance metric. I assume this would be a firmware update with an updated menu option.

I assume if the sensor has not been replaced that there is no serious issue with overheating, as some have reported with the a7rII.

Speaking only for myself, the camera is secondary, it is the image that counts in the end. If a camera serves you well in creating the image you had in mind then so much the better. Also take into account the media in which the image will be observed. For example, posting on Facebook, web pages, small or large prints etc. etc..

Now ask yourself how many mega pixels do you need to meet the presentation media requirements?

Who is your intended audience of the images you create?

What are they looking for?

Start with the end product and work you way back to the camera. This way you will establish the requirements that the camera must meet in order to satisfy the observer of your images.

If you do not determine the requirements you will spend thousands of dollars and countless hours chasing after the wind. I know this from first hand experience.

Remember you create the image the camera merely records it.

Why buy a digital Leica rangefinder in the first place? Just get a used M6 and load either B&W or color film as the need arises, scan the film and enjoy the best of both worlds.
