I'd like to know what you are photographing and how you are using those photographs that makes you so much more picky than others. The only thing I can think of is massive, billboard-sized prints that are displayed in locations where the viewers can actually walk right up and look at the images from a foot away. Are you Andreas Gursky?
Hard to argue with what you just said, because it totally makes sense. The bad thing about knowing the truth is that you stick to it, not wanting to find other truths.
Your opinion reminds me of the conversation 5 or 6 years ago. "Nobody has 4K TV and there is no advantage of having a 4K TV unless you watch and sit 1m away from it". Yet today, every new camera "must have" a 4K. Canon made a mistake listening to that kind of truth, will they make the same thing again with IBIS and megapixel race?
The idea behind innovation is so that people can find a new way of using a gear. Sorry if I do not share with you my ideas, at least not yet. It is not nice of me to behave that way, but allow me to do so.
My attitude toward photography is simple: "how can I stand out if I shoot like everybody else?". I hate repeating what a billion on our planet is doing. I want to do something else.
Maybe, I do not want to use a tripod on location because of security and other restrictions. Maybe, don't want to shoot tight any longer. Maybe, I don't want to be bound by framing properly rule any longer. Maybe, I found a way to shoot close ups the same way as full body shots. Maybe, I don't want to shoot at 1.4 indoors any longer. Maybe, I want on-location shots to look like in-studio shots. There is so much "maybe" that you could explore, then why stick to the way of your grandpa?
I hated shooting in mixed temperature lighting, until I discovered the work of Jake Hicks. The dude found his style in mixing colored light. That is the inspiration I need from others, not the ones who try to convince me that everything has been discovered.
I hope that shines a light on my arrogant attitude not to share with you what I shoot. Believe it or not but I do not want to be Andreas Gursky.
I am a firm believer that camera sales do not depend on the truth. It depends on what people believe to be the truth.
If I am convinced of the advantage of having IBIS when shooting a higher megapixel on-location, there are possibly others as well. The only question is how many?
