This series of articles on the iPhone Pro Max, with excellent photos by a pro photographer, makes one wonder what specific need there is for a heavy camera that costs (with lenses) more than 1500.
I have a problem with iPhone ergonomics (I have only an SE model), but apart from that, the price level of this new device, while excessively high for a phone, is considerably less than my investment in my Canon R6 and lenses. If one considers the camera function to be primary, with a working phone and internet connection as subsidiary benefits, 1500 is a good price for the quality demonstrated in the articles. Of course, it will not replace the situation where a tilt/shift lens is required, nor the extreme telephoto needs of the birds in flight photographers, but for everything in between it seems to work well, do more non-photographic things, and take up much less space in the pocket than my Sony Rx-100.
Food for thought!
