Do not forget redundancy...
I always have on my hunting belt a best quality compact camera, so I can shoot important pictures with both camera AND iPhone, so that I have redundancy in case I loose one of them (or one of them gets stolen, damaged, etc.). I agree that I do not look at my pics collection very often, but there are pics that I would really not want to loose in the field or on the trip before I could backup them, many of those shot while hunting, fishing, climbing, etc.
I also increase redundancy by purposefully using smaller memory cards that I change everyday rather than shoot 10 days of hunting on only one larger memory card. If the only memory card gets lost, stolen (in the camera) or damaged, you loose everything. If the "daily" card gets lost, stolen, damaged, you only loose one day...
...and quality...
iPhone pics are amazing these days, but still do not offer the level of quality that is achievable by real cameras, equipped with a quality zoom lens even if compact. It all boils down to sensor size, and there is simply no arguing that a "chip" sized sensor on a phone cannot compete with a 1", 4/3rd, APSC or full frame sensor. Period.
An iPhone 1/3.2" sensor has a surface of 15.5 square mm. A classic 35 mm film camera or a "full frame" digital camera has a sensor than measures 864 square mm. 15 mm2 simply cannot compete with 864 mm2 in terms of capturing an image.
+1 on the Sony RX100 a.k.a. "Best high-end pocketable compact" as reviewed by all pro sites and pro magazines (dpreview, c/net, cameralabs, pcmag, etc.) for the last 7 years...
In its 7th iteration for 2019, the RX 100 has not been beaten since it was released in 2012. I still use an original 2012 model and it is still about perfect... The 7 iterations are for the most part more 7 variations (different zooms, different screens, different viewfinder, etc.) than they are 7 improvements per se, and the original RX100 is still being made. Chose a RX 100 I, II, III, IV, V, VI or VII based on what features are more important to you, but they all come with:
- 1" type sensor (116 mm2) vs. most compact camera 1/2.3" sensor (25 mm2) vs. iPhone 1/3.2" sensor (15 mm2). HUGE difference...
- capability to shoot in RAW format in addition to JPEG: allows for professional editing of pics
- capacity to shoot A, P, S, M and full auto "intelligent" modes
- 28-100mm (equiv), f/1.8-4.9 Carl Zeiss zoom
In so many words, it is a compact with as much or more capabilities than many DSLR, and it is a rare iPhone pic indeed that is better than a RX100 pic, even in automatic mode...
....but shooting pics or bullets, I need to chose...
I have personally given up on taking a full frame sensor (864 mm2 !!! the digital equivalent of the old 35mm film) DSLR camera in the field (mine is a Nikon D3S) with one or two objectives
when I am the one doing the shooting. Yes, there is the issue of bulk and weight, but more to the point,
I have found that BOTH hunting and shooting good pictures are 100% focused activities, and I am simply not able to do both simultaneously.
To me the compromise is to have great trophy and occasional action or landscape pictures (never enough in retrospect) from a quality compact camera (Sony RX 100) always on my belt, AND acceptable quality - and easy to send - backup pics from my phone.
