A7R Noise and artifacts Problems

[Ideadores]

I own a sony a7r equipment and the FE2835 ZA lens, as well as the LAE4 adapter: 

I bought this equipment a few years ago with the thought that in the future, I could dedicate myself professionally to the photography (social reporting and stock photography).
Unfortunately now that I have finally been able to do it, it turns out that my equipment is not appropriate, I have sent more than 500 photos to shutterstock.com and only 50 photos have been accepted, since the rest have been rejected for technical reasons, always related to topics focus and photo noise ...

 

I have done a deep research around the subject, and it turns out that everything is due to the same architecture of the camera, (moreover I found out that this is a camera recommended only for landscape photography):

• It is a non-stabilized camera (easier to generate luminance noise)
• Low-pass filter removed (generates color noise)
• Generates temperature that results in the presence of color noise
• Additional, the FE2835ZA kit lens is a non-OSS lens

 

I have always been a SONY user since when it was called Minolta, then I had the sony A100, later the A550 and now the A7R, but I am seriously considering the change to another equivalent brand, SONY products although they are not the cheapest, so far I was blindly trusting in its quality, MY ERROR! It does not seem like a good practice for your company, because surely you knew that this particular model was going to have performance problems due to the technical limitations that I have just listed.

 

On the other hand, I see that their products quickly stop receiving software updates, basically it seems that we are talking about a programmed obsolescence issue, unfortunate because when we thought of SONY we imagined a product of the highest standards, FOR LIFE! I think that is not the case anymore.

 

Please bear in mind that those of us who use SONY for the most part, are not professionals, and that many like me, make immense financial sacrifices to buy each piece of equipment, much less have the money to change product version each year; Many of us INVEST in a SONY camera, thinking that entrepreneurship can be done with it, but always in the future, with the uncertainty of what is happening in the economy, especially in poor countries like mine (Colombia).

 

Nothing else, I appreciate reading this message and I hope it can be taken into account for the improvement of your products and so that you take into account that your market is very wide and varied, and that many of us are not a high-power population acquisitive, also for you to think about a more sustainable world, through ROBUST DESIGN, banishing from your practices the subject of PROGRAMMED OBSOLESCENCE.
