I have a Samsung Galaxy S5 (but soon to upgrade to Note 8). When I go travelling I always take with me my trusty Nikon D7100 digital SLR with 18-85mm lens. Smartphones can take great photos these days but are still lacking due to their lens.
Conversely, my Nikon camera, although a very good camera, is heavy, cumbersome, and I also need to bring the case and charger.
Further, I can't backup to cloud, edit, or share (email, Whatsapp) my pictures directly from the SLR camera. For this I'd need to bring a laptop with me, whereas with my phone I can do these three things from the phone. Also my phone can GPS-tag the photos, whilst to do this on my Nikon I'd need to buy a separate GPS unit to attach it to the camera, thereby making it even more cumbersome.
Viewing recently taken photos on a smartphone screen is much more pleasurable, not to mention the pinch-to-zoom. Also, my phone these days has more free storage space than my camera has in total.
So, to my question... Is there a way that I can have the best of both worlds? Does there exist some sort of 'cradle', where I can attach my current Nikon lenses, and a shoulder strap, and then just slot in the phone to turn it into a fully functional DSLR camera?
As for connection between the phone and the 'thing', I initially thought WiFi, but I think that this would cause a Osh with the viewfinder, so probably USB-C would be best. Plus, with a cable you could potentially or a battery inside the thing which could be used to charge the phone.
Does such a thing exist? I've seen those Sony lenses that connect with WiFi but they don't seem to be quite what I'm after.
