Hi all. I thought I knew how to take long exposure photographs, but evidently I was wrong. My previous experience was with a Canon 80D DSLR. I've never tried it with a mirrorless camera.
I don't do it very much but went out a couple of times the last couple of weeks to brush up on it and had some weird results.
I currently shoot with a Sony A7RIII. I was using a 10-stop ND filter mounted on a Tamron 17-28mm lens and wanted to use f/8 aperture. I had my ISO set at 100. I set the composition then put the filter on.
I was just playing around so I didn't have a particular exposure time in mind for the clouds I was using as my subject, I just wanted to do something like between 3 - 5 seconds.
I was in manual mode. As I was adjusting my shutter speed I noticed that my aperture started to change. I didn't think that was supposed to happen. Clearly I don't know what I'm doing.
Was hoping you could recommend a good tutorial that would help me get back on track.
*Please note I also tried this with a Sony 70-300G OSS lens and had the same issues.
Any help would be appreciated.
I got a problem during a recording.. I change the battery without stopping the recording.. So, the rush didn't register on the SD card as a '.MP4' file. Instead of that, I got a '.RSV' file (visible on my computer) that I can't read as a video, and which has the good size of my original rush (29Go).
I want to know if you have any idea about how to open it or convert it as a MP4 file?
Thank you in advance. Greetings.
Does anyone else have an issue with excessive spotting on photos with their mirrorless camera?
I have a Sony Alpha a7 iii used mainly with a single E-mount G-series lens with a Hoya DMC UV filter... But in recent months I've noticed that I am editing out dozens of spots from marks - on the lens or perhaps from the camera. I've tried cleaning the filter, the lens, blowing out dust from the other end of the lens/inside camera but a lot of these marks/spots remain. I rarely change lenses.
I previously used Canon DSLR cameras & lenses and never had the problem to the extent I am having now. Any ideas? Is this a 'feature' of mirrorless cameras??
I just got used A7riii and the touchscreen does not work. I have tried updating the firmware, resetting the camera multiple times, changing the setting that has to do with autofocus (yes I'm aware that you have to turn this function on, I've turned it on and off so many times already) I'm not sure what I'm missing. The touchscreen is just unresponsive. I've done everything short of sacrificing a goat. Has anyone else run into this issue before? The previous owner says that they never used the touchscreen so they were not aware of it. Please help me figure it out. It cost a lot of money.
