Is there even a point?

Is there even a point to having a full fledged DSLR or a mirror less camera at this point?  I’ve been using my Apple iPhone 12 Pro Max with 512GB of internal storage as my go to camera for the past couple of months.  I shoot landscape photography 100% of the time.  I do sell a lot of photography on various micro stock websites.  All of these require at least a 5 megapixel sensor.  The current iPhone has a 12 megapixel sensor which is more than enough for micro stock and even for my personal website where I sell photography as well.  The hardware and software is there to make a living with just the iPhone.  The equipment and software will only get better.  

There is absolutely no point in lugging around a mirror less or a full DSLR with you all over the place.  I think I will be selling all my photography equipment once the new 2021 Apple iPad Pro comes and just shoot with the iPhone and edit everything on the M1 based Apple iPad Pro.  I can use my Apple Watch (v6) as a camera remote.  Yes, the Apple Watch can be a remote to my iPhone 12 Pro Max.  I can edit everything on the 2021 iPad Pro. I can also have everything backed up to the 4TB of iCloud storage and never have to worry about losing a photo to a dead external hard drive.  I cannot wait for the 20201 iPad Pro to come in a month or so.  

I’m currently on a contract with another government department. Probably my last one here in Ottawa as I plan to move out west in September.  With or without the fiancée.  I know my heart and soul belong out in the mountains.  

Since the iPhone 12 Pro Max can and does shoot ProRaw files, I can create up to 30-40 megabyte files out of a 12 megapixel sensor.  Yes, you can do that with an iPhone.  Since it is such a small sensor, I want to try it early in the morning and in the evening to see how it performs.  I have to see it for myself.  I want to see what I can create and how the iPhone 12 Pro Max handles in low light situations.  The only worry I have is the performance in low light situations.  I shoot the majority of my shots between 7am and 7pm during the summer anyways.  Another worry is reach of the lens.  The longest the iPhone can go is 70MM as far as shots go.  But with Pixelmator Photo running on the iPad Pro, I can increase the resolution and crop closer.  So I guess that solves that issue.  :)
