In some ways it reminds me of my Pentax 67.

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.

If you cannot afford this particular lens and if you can find it, consider the Sima SF lens. It is 100mm F/2.0 macro MF. It employs perfectly circular aperture disks, is low cost, plastic construction and produces interesting results.

Speaking for only myself, I use what works to achieve the desired results.

Be it fog the filter with your breath, grease on a filter, a hole in nylon stockings over the front of the lens, Zeiss soft filters, optical lens designed for the application or a lens with less than perfect optical attributes and post processing.

Over several decades I have found each solution set has its unique strengths and weaknesses. But I never close my mind to new opportunities.

So take it with a grain of salt when you read the other comments that they have found the magic bullet for all applications or put down the Lensbaby 56mm lens without actually testing it for themselves.

Once I receive and mastered the lens I will post some images along with my opinions.

On the subject Sony full frame lenses, where are the Loxia lenses listed on DPReview? I tried both the Sony and Zeiss lens directories and could not find them listed. Thank you in advance.

On Sony Alpha 7S Review (494 comments in total)
In reply to:

RC: The 7S is a great camera, I used it during last new year's eve without a flash and the resulting photos are just amazing.
HOWEVER: What I am missing, from an amateur's photographer point of view, is a decently fast zoom lens (24-105 or 18-200 mm).

I agree there is a serious lack of lenses and if it were not for the third party adapters I could not recommend purchasing the a7S. Speaking from personal experience with the adapters and a good selection of manual and AF lenses, the lack of Sony lenses is not a issue. If I were in the market for additional lenses the high sensitivity of the a7s no longer forces me to buy fast lenses. Another reason I purchased the camera is for astrophotography. This is where the a7s really out performs all the other cameras I have, since it enables me to accurately focus on stars that I cannot see with my eyes in the sky with heavy light pollution. With a push of a programmed button I can magnify the field of view to such a degree that the slightest touch of the focusing knob makes the faintest stars appear, and another touch they disappear. The result of accurate focusing and a light sensitive camera is very rewarding to me.

d2f: Referencing the comparison table above: Can someone tell me in detail what "self cancelling" means under optical low pass filter for the 5DS R?

So if understand this correctly the net effect of the two filters cancelling each other out is to keep the optical path the same as if only the anti aliasing filter were present. I assume this somehow retains the focus path attributes to the sensor to mitigate the need to have a second level calibration for this particular model. If the halo effect is present I assume it should be measurable with point light sources like stars.

guinanji: Question:
How many megapixels is too many? I mean, if there was a 1000 MP camera, who would want it? Who would need it? For the type of photography you do, if there was no limit, how many MP would you want/need, and why?

Will the answers to your questions will make any difference in the end? Technology keeps moving forward independent of any individual opinions. The camera companies are guided by sales and profits. They have a vested interest to push the envelop if only to gain bragging rights and a marketing edge. They are riding on our fear of inadequacy while feeding our pride with their products.

d2f: Thank you for the first impression write up and I look forward to the final report. With any luck some if not all of the recommendations mentioned will be included in future models or firmware releases.

Hopefully either camera will bring out the best of any lens attached to it and under the right conditions produce high quality cropped images.

My first impression is either camera would ideally suited for the commercial studio environment.

Two questions; does any digital camera offer electronic anti aliasing filter, by this I mean where the end user can switch it off and on? If not do any of them offer a user replaceable filter (similar to replacing a focusing screen except in front of the sensor)?

To answer your question I Googled the subject and yes the Pentax K3 can physically vibrate the sensor to achieve the desired effect. Another K3 reviewer mentioned the on/off anti-aliasing simulator provides all the benefits of a true optical anti-aliasing filter. I should have clarified my question was not mechanical implementation but electronic solution.

All optical lens designers are constrained by design parameters, the result of which determines the size and weight of any lens design they design. Given the sensor geometry & distance from the lens mounting surface, aperture, focal length and desired image quality it should not be too surprising to find DSLR and mirrorless optics designs are approximately the same as the focal length increases. Other parameters such as construction materials, weather sealing and auto focus implementation also come into play since the larger the optics the greater the weight and larger the motor assembly. That being said the size differences between DSLR and mirrorless lenses may appear in wide angle lenses where rear optics can get closer to the sensor on the order of mm. If that is the case then it would be unrealistic to expect the current FE lenses to be significantly smaller or lighter than their DSLR counterparts.

On article CP+ 2015: Nikon shows off new D810A (65 comments in total)

Congratulations to Nikon for taking their first step into the astrophotography market. I look forward to the review on Cloudy Nights. Meanwhile it will be interesting to see Canon's response, maybe a 6Da is in the works. Also for those who cannot afford the D810a almost any modern digital camera can be modified for astrophotography IR spectrum at a cost of approximately $350. For those who do not want to modify their camera, but are interested in astrophotography they can buy a Sony 5T with the IR modification from eBay for $369.

On article High-end full frame roundup (2014) (607 comments in total)

Looks like Sony has another winner. I have not seen something like this (FF with sensor stabilization) since they released the a900 back in 2008 Back then it cost around $3000 and had issues with sensor noise This reincarnation only goes for $1700, which to me represents a great value albeit expensive and at present a limited quality lens selection. Anyway I look forward to the DPReview full test report.
