Surely you would not be the only Canon user here,there must be more ? Seneca shoots with a canon, and we are very glad she is back on the forum.
For the past several months, I have been combing the web and considering making a shift from Nikon and my D750 to a Canon system. As a 40-plus year Nikon shooter, I do not make this consideration lightly. A few factors I'm currently weighing:
1) I do photography mostly for our family and my own "fun" but do have some modest "business" involving photography so I need to remain up-to-date as much as my budget allows.
2) The new mirrorless cameras are really not very interesting to me. After all these years, I am very comfortable with the DSLR form factor and will keep using it until it is no longer available or ceases to function, which ever comes first ... at least until I cease to function!!
3) My current lineup of lenses and equipment is really more than I can use and several items have sat in the closet for years.
4) Although I love the images produced by the D750, the one area where I see it lagging a bit vs Canon is the adoption of some modern tech. Yes, the D850 addresses many of these shortcomings but at a $$ price I cannot afford!! What's missing? BT/NFC connections for easy access to social media destined images (something my wife urges me to do A LOT!!), built in GPS (no need to have a GP-1 dongle and a cable plugged into the camera to capture GPS info, something I actually use a lot), and a touchscreen monitor with iPhone like gestures. The Canon I am looking at, 6D Mk II, has all of these. The D750, none (well, it does have a clunky wifi ability built in, but it's certainly nowhere near as seamless as the BT/NFC connections a la D850 and Nikon's SnapBridge). None of Nikon's FX DSLRs have GPS built in.
5) Upon receiving the new gear, I would be eligible for Canon's Pro Services right away. I've been waiting to hear about my NPS membership application for three months now (Nikon says they are "having issues" and I might hear something by next month.) Based on the few times I've needed support for my Canon printers, I think I'd also probably give them a nod over Nikon's USA support system.
6) Finally, and this is actually perhaps my main interest ... I think I need a new challenge. Learn and use a new system, probably with a lot of failures and some frustration along the way. My consideration of this plan is therefore more of a learning a new system vs "I hate Nikon"!
I've been dealing with a number of camera stores concerning a trade package, and find that I can trade my gear for a pretty closely matched set of Canon gear that I will actually use ... and get some $$ change in return!! Yeah, the Canon lenses are all f4 vs a couple of my f2.8's, but I really do not think I'll actually miss one stop in my "real" world. I'll end up with pro grade EF IS USM f4 coverage from 17 to 200 mm, which is close enough to the same coverage as my current 14 to 200mm range. I have found no need for anything outside that range since our son headed off to college three years ago and doesn't have me shooting his sports any more!
The 6D Mk II seems to be pretty comparable to the D750. There are some who swear the image quality and dynamic range is not as good as the D750, but based on the sample images (both jpeg and RAW) I've been able to download I'm not sure I see any significant difference at all. I did watch one YouTube comparison where the Canon really looked terrible compared to the D750, but after looking at (and pixel peeping) dozens of images, I'm a little suspicious of the guy's methods and conclusion. My soon-to-be 68 year old eyes just do not see much of a difference.
In addition to just letting folks know I'm considering this ... can I retain my membership here? I must say, I've yet to find a Canon-focused group that's anywhere near as terrific as this bunch!!
Also ... I have not yet pulled the trigger on all this. I suppose I'm dragging my feet a bit because I am so comfortable with my Nikon system ... and it IS a good system. Removing the $$ factor makes this all the more difficult to come to a final decision. But, I do really think I need a new challenge.
I will also say this ... IF I make this move, the folks I'm dealing with are not interested in a lot of my Nikon accessories. Keep your eye on the For Sale forum for some nice buys!!
Stick around, Minuteman!!! Please!!
Best wishes to you with your decision. From the down side I would really miss the f2.8 of the Nikon lenses. Hope you choose to stay here on the Cafe whatever choice you make.
