When I snapsort compare the Nikon D5500 and the Canon 760D, the Nikon is far better spec-wise, but the 760D is more expensive. Are there any specs that are unknown to me that are better in the Canon which makes the Canon more expensive?
Specs aren't everything.
The Canon 760D has a number of usability features the D5500 doesn't.
- Two-wheel controls (easier to operate than a single-wheel model)
- A top LCD
- true mirror lock-up
- DOF preview button
- high-speed sync flash capability (called FP in Nikon terminology) with an external flash
- wireless flash master/commander built-in
- autofocus with any current Canon dSLR lens (D5500 can only autofocus with Nikon's AF-S lenses.)
Since some of these features actually do require additional hardware, that probably explains the "premium" for the Canon body. A more direct equivalent to the D5500 is probably the 750D/T6i.
Yes, there are some features in the 760D that are overlooked in your comparison:
1) top LCD screen 2) individual dials for Aperture and Shutter speed 3) larger buffer that allows you to take more photos in a fast burst 4) better autofocus in Video and Liveview
The 760D is only about $100 more than the D5500. Price wise, the direct competition for D5500 would be the Canon 750DD which lacks the top LCD and rear "Quick Control Dial". They are both about $750.
Sometimes the cost might reflect the customer support given by Canon, or in other words the support network behind the product. I know first hand that Canon support is quite good compared to what I have read and heard about from Nikon eg the dirty sensor on one of their new camera models awhile back. Also comments by Roger Cicala at Lens Rentals about his experience with after sales service offered by Nikon. I reckon this aspect of the purchase shouldn't be underestimated.
