Originally posted by biz-engineer When I upgraded from Pentax apsc to Pentax full frame the situation was different, I spend the whole bunch of money for a bigger sensor format, more resolution, more dynamic range and more modern lenses and more versatility (crop mode). If I was invested in a Canon or Nikon full frame systems , I wouldn't switch to a Sony A7R4 either. It's just that I don't see enough value for switching between two full frame systems that are 3 years apart, and especially when the sensors are made by the same manufacturer and with almost identical still imaging properties. If other people have money to burn for a little more gadget features here and there, that's their money not mine.
Depends on what you shoot and depends also on the system you invested in.
Some are willing to work arround the limitation of a camera (or lens) by shooting portraits at f4 or f5.6 instead of shooting at f1.4 or f1.8. Some are shooting wildlife in JPEG so that the camera can write faster on memory cards, etc. Nothing wrong with the fact that they chose this route. But there are others (myself included) that don't want to find works around every time they go out shooting. If I'm shooting a portrait on a crowded street I don't want to shoot at f4 because at this aperture all the people around the model will be recognizable and I don't want that. Those people will also be a distraction from the main subject. At f1.4 I don't have to worry about this or about not getting the shot due to tiny DOF because of this great feature (to me) called eye af.
The same thing on a corporate event when I'm not allowed to move much because some speakers are shy in front of cameras. I have to shoot with 135mm f2L lens at f2 to keep the distance, to isolate the subject and to keep the ISO around 4000. I don't want to shoot at f4 in this situation. Don't get me wrong, I can make it work with a K1, but it is easier with eye af and a fast lens and that's why I like the eye af feature.
And I do want more than 4 fps with fast Af and fast reading files on memory cards so that I don't need to reduce my keeper rate to 60-70%. It's a good percentage, but I rather have 80-85% keeper rate.
This not so important aspects to some are very important to others and even if it seems much money invested, with a good financial plan I have no troble paying for my gear and save also money for upgrades.
Sony improved in A7R IV some things I'm interested in: eye af, ergonomics and the EVF. Given the fact that EVF still gives me some headaches, if this EVF will be much improved and if it won't give me headaches, I would pay the money only for EVF if I were a photographer in need of a high resolution camera.
And again, I have my own training company. I don't live from photography. But this hobby is self sustaining so complaining about how expensive cameras and lenses are is not in my agenda. I don't have to save each month some money in order to buy a good lens two years later.
There was a time when watches were a big passion of mine and if photography seems expensive to you, wait until you buy a Glashutte watch that won't produce any money.
