Hi. Newbie hobbyist who started last June. Does anybody know what would cause the "bullseye" in the center of this shot? I shot this using an a7r iii with FE 2.8/24-70 GM lens. My settings were 15 sec, f/4, iso 800. Also, I didn't see the bullseye on shots at 5 sec, f/4, iso 800. I had Long Exposure NR off for both shots. Thanks.

I currently own an A99. I have some investment in o A mount lenses, but not too much to the point where it'd be hard to justify a switch to the E mount. I like my A99. However, I am interested in taking advantage of some potential savings while I can still get some money for my A99. I am a scuba diver and one thing I have been frustrated with is the ability to get an underwater housing for my A99. It seems that most of the underwater housing companies have moved on to the E mount cameras. I am currently a hobbyist whose done some professional work. I am planning to take on more professional work. My focus is will be on architectural, commercial, and product primarily. I may also do some portrait photography. I will also use my gear in underwater situations. That will be more of a hobby (vacations, etc.). I love the idea of going all-in and switching to the A9, however, I can't justify the spend for that. I do like the idea of taking advantage of some savings on the Sony A7R II that are going on now. However, I understand there are several limitations with that camera. So, then I come to the A7RIII versus just upgrading to the A99II (I fear the lack of an underwater housing here). Given the choice between the A7RII and the A7RIII, which would you choose? Or would you bite the bullet and just go for the A9? I am thinking about the long term. I'd like to invest in a system that I'll use for the next 15 - 25 years.
You answer your own question why: " absolute best image quality despite bigger file size and more noise on pixel level."
Given my experience with 35mm, med and large format I know what increased resolution looks like even with much smaller prints of 8x10 and 11x14. In this case its certainly not marketing crap. Its a real world improvement. If you are using the kit zoom then perhaps there is not much more to resolve but again I'm using quality prime lenses and I know
Hello you all!
I'm trying to make an automatic turntable for object 3D scanning (photogrammetry).
I use this connector to interact with camera multiport:
Sony pinout on Multiport
For now it's working well, I use some custom electronics to trigger the shutter connecting trigger pin to GND. But it only work with the self-timer activated.
It makes my scan process really slow then (even with the 2sec selftimer)
Do you know a way to use directly the trigger pin (I mean,
I was also going to mention the A7x's. 24mp is absolutely fine for me, image quality is great and it's more than big enough for any print I would ever want to do. Until then, I don't see a need for more.
For what it's worth, I previously owned a Pentax K1 (36mp). It was nice to have that additional crop-ability but it was entirely unnecessary for every scenario I would use my photographs (currently).
many forums and the "pros" once were certain that the star eater issue makes the Sony A7 Series unusable for astrophotography but I always had good results with my Sony A7rII. So I recently went ahead and had it astromodified. The thick IR-Block Filterglas was replaced with a thin Baader substitute that lets IR Light down to the h-alpha line and the sII line through to the sensor with high transmission. The results can be seen in detail on my google drive link here:
Honestly, why do you need more MP? 24 MP is plenty for any kind of print you may ever want to make if you factor in optimal viewing angle. All these bells and whistles you speak of result in a vastly better image than just boosting the MP-count would (better AF and subject tracking, better low light ISO-performance, etc). Higher MP is just marketing crap unless you plan to heavily crop or print billboard size and stand with your nose against the canvas.
For good reason the A7x you refer to
