Disclaimer: I am not a professional so don't expect nuggets of wisdom dispensed here. This isn't a review either but rather simply the shooting experience with the D750 from my POV as an enthusiast and based on my preferences & needs. All camera related products mentioned were purchased by me for personal use. Full-sized pics (along with EXIF) for this write-up can be found in the three Nikon D750 Albums on my flickr page.
I have enjoyed photography dating back to the film days of my youth and have been engaged in it on/off (but mostly off) for the past few decades. My first DSLR was an EOS D60 after the mass exodus from film and I shelved my EOS3 (which I still have) but re-used the EF 28-135 IS USM. This was during the days when manufacturers were still touting megapixels as the sole important spec for digital cameras which I naively bought into thus was amazed at the quality that was produced with "just" 6MP.
(shot w/D60 hand-held at awkward angle with close-up filter so not the sharpest…)
Being a gear head, I've yearned for a FF Canon DSLR for a while (beginning with the original EOS 5D, then the Mk II and most recently the Mk III) but I simply couldn't justify the cost of one especially factoring in nice glass and the fact that I wasn't a pro. So I stuck with bridge cameras (Canon S3 IS & Panny FZ-150) as well as various P&S (Sony DSC-T1/DSC-T9/RX-100 & Panny LX-5).
They served my purposes well for taking family pics, trips, the occasional events & mostly what I've been doing a lot of which was predominantly low-key photography and videography of gadgets I reviewed.
I was pretty satisfied with the results and given the D60 was bulky and heavy to carry around and thus not getting much use, I sold it.
In my heart though, the desire for a FF DSLR was never extinguished...
Then things changed…
I got involved with my church's AV team and started to do a bit of shooting but was often dismayed by the results of shots in poor lighting conditions (w/the FZ-150). I started looking into DSLR's again and still recalling fondly the Canon products I've used and the acclaims of the 5D3 I wanted one bad but then the D800/800E with its 36MP launched and having still not been weaned off the MP lies, I was instantly smitten. Never mind that I wasn't planning on producing billboard sized print outs, I NEEDED 36MP! You can imagine my dismay when I found out the price and being roughly in the same league as the 5D3, again I had to really work on justifying the purchase.
To make a long story short (unless the inability to "pass" G.A.S. due to paralysis by overanalysis is of interest to you…) despite a brief flirtation with M43's (again arguing against the weight and size of a DSLR), I ended up acquiring a D7100 paired with a Sigma 17-70 C. Having spent so much time taking pics using screens with live WYSIWYG previews, I had to reacquaint myself with shooting through a viewfinder again as well as learning to use a DSLR with its multitude of menus, buttons and customizations possible. It was much harder to get shots the way I had with non-DSLR's and in spite of the learning curve and some less than stellar results initially, I was determined to stick with it.
The low-light shots from the 7100 at church were certainly a few notches above the FZ-150 but still not quite where I wanted them to be in consideration that I wasn't keen on doing a lot of PP. Therefor I eventually sold it to my bro-in-law and got a D600 (loved the D7100 though…). The reduced noise (especially of the purple variety) in Hi-ISO shots was certainly worth it as evidenced by these low-light SOOC JPG's comparo test I performed: D7100 vs. D600 vs. 6D
However, despite liking the Nikon layout and results, I was still drawn to the stellar low-noise SOOC JPG's from the pro photographer at church who was shooting with various Canon bodies (5D Mk 2 & 3 as well as 1D X). Thus When the 6D was released I did a bit of research and based on various results (with Hi-ISO noise being a primary consideration) and being satisfied with what I saw on DPR's comparison tool, I picked up a kit w/the 24-105 lens with the ultimate goal of deciding whether I'd choose Nikon or Canon for my shooting needs.
The 6D's pics SOOC were certainly cleaner but I just liked the look and feel of the images from the D600 better. I also preferred the configuration of the camera and controls as well and found it fit my shooting preferences better. In the end, after spending extensive time with both, I feel one really can't go wrong with either of these phenomenal cameras but it was going to be Nikon for me.
Enter the D750
When the D750 was announced, there were multiple factors that drew me to it, namely: improved noise on Hi-ISO shots, tilting higher-resolution screen, built-in WiFi, one touch zoom preview, deeper grip & improved AF. Given I’m no stranger to early adoption, I elected to pick one up and decide if it’d be a worthy upgrade over my D600, I’m glad I did…
