Wally The Confused

Thanks for the explanations , I never knew that ! Im sure these posts have helped a lot of people avoid the same problem ! Glad you had your warranty, and it took care of things.

I was going to suggest pollen, until I saw pic 4. I have not seen anything like it. I hope you get it sorted , and post a solution. All I can suggest, is taking it to a reputable camera workshop, and have them look into it. Sure its the sensor, and not something in your lens ? Zooming can suck wierd stuff, inside the lens too ! Good Luck

I will hazard a guess on this. The a 58 is Aps C , the A 7 is Full Frame. It could also be down to Google Fotos, not accepting Raw images ? Go into settings, on the A 7 and try Raw + Jpeg, or just Jpeg , take some test shots, then see if the jpegs appear, on google photos , or not. Good Luck

I have no idea, if an update, would cure that ! I would take it back to the dealers, or, if out of warranty, take it to any recommended repair shop. GOOD LUCK

Even as you are backpedalling now, conceding the possibility of only a little movement, before being overwhelmed by air pressure forces, this still remains nonsense, as the undisputed forces generated by the pressure differential between inside and outside don't exceed 15 Newton on a zoom lens with dimensions similar to a 100-400GM. This minuscule force does not qualify as making any zoom action difficult or even impossible. Any claim to the contrary does however qualify as nonsense. Where, am I backpedalling ? I am proving you wrong, on all fronts ! I even have independent reviews, from honored photographers, & scientists, to back me up ! Even people on this very forum ! Perhaps you subscribe to the scientific equation, that proves, Bumble Bees, cannot fly ? There are none so blind... As those who will not see ! I am not wasting any more of my time, on this thread !

You did good ! 100 - 400, is a bit beyond my style, but you obviously know, what you are doing ! Jeez, Years ago, my mate Steve, who was a Racing Instructor, right there, told this fantastic story, about some professor wanting to drive his innovative sports car, around the track ! Expecting some sort of exotic design, the office gave the professor, a trial time & date ! On the day, this so called Professor, turned up, in what looked like, a battered Ford Escort ?? OK, he had to tune the Engine,so he needed a few moments of OOOOOHHHMMMM Then he played a Casette Tape, of Blackbirds singing ! By then, not only my mate Steve, but also the rest of the staff, started wondering, what the hell is going on ! Anyway, on the green light, this , so called Professor, took off... Then he crashed on the first bend !! OK .,he was not injured, but he knew exactly ... who was responsable !! A group of dissident tibettan monks, who were determined to thwart his efforts !!!! Steve & his crew, went for a drink, while the professor waited for a tow truck !

b I guess, you did not read my post very well ! I clearly stated, that , somewhere, on Youtube, I saw a clip of a camera being activated in a smoke filled box, that showed how an extending lens , sucked outside air, into the body. Unfortunately I did not bookmark the page, otherwise I could have posted it here. Never thought I would need it ! It was to do with an owner of a ?? G10 ? complaining about dust on his sensor, and ? Canon ?? reluctantly honoring their guarantee ! So do not call it NONSENSE ! As said, I cannot find the video, but i found this ! https://photographylife.com/what-to-do-with-dust-inside-lens Now, read that ! And tell him, he is talking NONSENSE ! You might be wondering how and why lenses get dust inside. Let me explain a couple of things about lenses. Every time a lens focuses or it is zoomed in and out, it “breathes”. And no, I am not talking about the effect of lens “breathing”, when an image appears smaller or bigger when focus is adjusted – I am talking about the process of inhaling and exhaling. Lenses have to breathe, due to lens elements constantly moving inside them when focus is adjusted and/or when zooming takes place. Remember what happens with pressure inside a closed plastic container? If you try to reduce the container size, the pressure inside the container will only let you reduce it to a certain level before it pushes back. A simple concept of air pressure in physics. Now take the same concept and apply it to lenses. What would happen if lenses were completely sealed from all sides? You would only be able to zoom in a little before the lens would force you back to its original state due to pressure, especially on lenses that extend in size. A similar thing would happen with lens focus. Hence, there was no other way for camera manufacturers to design lenses – lenses with moving lens elements must inhale and exhale air. Look ! There goes Chrissie.... Shot down in flames !!!!!!!

That is Spot On ! Even with those fixed lens zooms. Any time you turn the camera on, and the lens extends , you create a vacum that can suck dust & pollen into the body, and sticks to the electrickly charged sensor. Somewhere on the internet, there is a brilliant youtube clip , showing what happens when you turn a camera on, in a smoke filled box. If the lens can extend.....then it is NOT sealed ! There has to be a micro opening , otherwise the lens would not be able to move. Cheers

I had not had the A 9 long, before the LCD packed up and you could only use the viewfinder. Jessops UK sent it for repair , within a week of getting it back, the same thing started again. Jessops then replaced theA 9 Body. I have not experienced your issues, but I only take photos. Daylight & night high iso, along with the odd flash foto ! Are you using video and continuous LCD lighting ? That is an area that I know nothing about , sorry. Ok you sent it back to Sony, I have to admit, they could have given you a better explanation than that, when you considder the cost of the A 9. Hope you find a solucion. Just a thought tho, The Sony A 7 S Series are specially for low light. Check the reviews , ken rockwell etc. Swopping the A 9 for the A 7 III or R III would probably be a worse option Cheers

Ok, I received a reply from D & G, which turned out to be a mistake. I took the letter + policy, to my local branch of Jessops, and the boss immediately said, that is a mistake ! He phoned D & G, and got me a full refund, for the 24 - 70 f 2.8. Ok, I paid 1899 GBP for it, now the price has dropped to 1799 GBP , and that is the ammount I will be receiving later this week, apparently. Ok, as regards jessops, Ive bought all my camera stuff from them, over the years, and , once cameras or lenses approach 1000 gbp or more, then yes , I have allways added their recommended extra cover ,through D & G. Thank You Jessops, for your professionalism and efficiency ! Thank god I took out the extra cover ! Independent Explanation, Not From Jessops ! Sorry to hear this Wally, and I agree it is terrible news! The reason the lens re-lease is on the other side, is because of the ability to add the LA-EA3 and LA-EA4 lens adapter and then attach A-Mount lenses. Those lenses have the re-lease on the other side like you would expect. I believe this is the reason for the location of the lens re-lease on the mirrorless cameras. I'm really sorry to hear about this, and yes it's a great thing you had the extra insurance for time like this.

see your time line point; however, after 50 years of handling Nikon SLR's, with the release button on the left, last year with my new Sony a7rIII was the first time I experienced the issue. I will learn and retrain and it won't happen again but it doesn't absolve Sony. EXACTLY !!!!!

Having worked for the MOD, doing the R&D on various things, If it was found, that an operator, could inadvertently trigger a weapon, while doing a routine maneuver , .... That was classed as a design fault and the " Trigger " was moved elsewhere, so it could not be inadvertently operated. Thats what we called a design fault ! Thank you Bokehobo, for your understanding. I am glad your lens did not fall off ! Going by the comments, you would think some people here, were on the Sony design team ! And I maintain.. the lens release button, should be either at the 6 o clock position or the 5 o clock position. C heers

If , like other cameras, the lens release button was on the other side of the lens , it would not have happened. Guess you have small hands.

Hi all. I had the A9, mounted with the 24 - 70 2.8. Ok the lens is quite heavy, and you have to support the camera, while the other hand does the zooming. I was doing some shots beside a boatyard, and was slightly down angled, while trying to zoom between the fence bars ! The lens release button, is just at the end of the handgrip ! Due to my position, long fingers, and gripping the weight, while composing the shot, meant that I had inadvertently pressed the lens release button ! Instead of zooming, the lens unscrewed, and dropped to the concrete. Strangely enough, the B&W UV filter, stayed intact, but about a third of the front lens scabbed off ! Also the mount got damaged so it would not return to the camera body. Thank god, I took out the extra insurance... I am 64, and never in my life, have I ever dropped a lens, until now ! My point is, other cameras I have owned, have had the lens release button, on the opposite side of the handgrip, so people with either large hands or long fingers, cannot accidentally release a lens ! Yes, I had the A 7 II for a few years, then got the A9, and never had a problem, until yesterday, where a combination of angle and weight, had a disasterous effect ! Thank god the lens is on the extended Jessops warranty through D & G . I wil keep you updated on this. Cheers
