Long story short I only need 1 lens to work and function a certain way. I do NOT need autofocus. But it's the new Sigma 14-24mm for Nikon that just came out a little while ago, not many people have it on their radar. I just need it to work on aperture priority mode and be able to bracket photos as well. But i shoot on manual focus at infinite. I'm wondering if only the more expensive adapters like the commlite will work with this function or if the cheaper 99 dollar ones will let me control aperture as well. I care about image quality but if the more expensive adapters are only that pricey because of autofocus I could care less. Any info would be appreciated, thanks!
I purchased a Sony a6500 last December and I've loved using it (aside from the battery life). So far, I've used it quite a few times to conduct interviews for short documentaries or promotional work. I've conducted many interviews without issue, until now. Since I'm often working alone, I set the camera up, adjust the exposure and focus properly, and then move away from the camera to sit down and ask questions after pressing record - I always shoot interviews in complete manual mode for ISO, aperture, and shutter speed. This time I was using the Sony G- f4/18-105 lens, it was very cloudy so I had the aperture set at (f4), shutter speed around 1/200ish, and ISO I always keep as low as I can at 100. When I pressed record, the interviews were properly exposed, slowly throughout the image became brighter and brighter. By the 9-min mark, the image is so over-exposed that it is useless, and I discovered this when uploading to my computer. Is this some kind of manufacturer malfunction, is it common, or am I now unknowingly doing something drastically wrong that I wasn't before? I've attached a couple screen shots of the moment I pressed record, to the moment I stopped recording - 9:16 to show you how drastically the exposure changed. Thank you for taking the time to help out!
