I've made the switch from Nikon to Canon, back to Nikon, back to Canon, and now, with Nikon again.
Why? Because I can (and probably because I have a serious problem).
Canon bodies I've owned to date: 5D, 5Dii, 1DMKiii, 1DsMKii.
Nikon bodies I've owned to date: D40, D70, D80, D90, D1, D700.
And to put things into perspective, this is my camera ownership in chronological order:
- D40 (end of 2009)
- D70
- D70s
- D90
- 5D
- 5Dii
- LX3 (what the!!?!)
- D80 with 18-200VR (what the!!?!)
- 1DMKiii
- 5D
- 1DsMKii
- D700 and D1
- 5DMKii
- D700 (today)
System switching is not for everyone, and I certainly would not advocate it unless there were serious issues you have with your current system (whether it be Sony, Nikon, Pentax, Canon etc). Luckily, I've always had a maximum of three lenses for each system so changing wasn't too much of an ordeal. I probably thrive on the change more than anything. So I am weird!
I personally don't have a preference to which brand is better. I don't think anyone can argue one over the other. The sole reason why I have switched systems, and back and again is purely based on pricing. I saw a bargain to be had and took it. I've never been overly invested into a single system. If I could afford it, I would like to have a Nikon and a Canon.
What I like about Canon.
1. The jogwheel.
Some people love it. Some people hate it. I love it. It makes navigating menus and photos so easy and smooth.
2. A lot of EF lenses available secondhand
I like to own stuff. I live to sell stuff. I don't know why I don't rent because it would be easier on my wallet but there is just something to owning something, even if it is for a few days. Due to Canon's popularity based on it's 5D back in the day, a lot of shooters are Canon users. This means the market is flooded with a lot of competitively priced secondhand lenses. All the more for me to play with! I'm a suck for fast lenses, and Canon to date, have the upper hand on the number of primes available. IQ-wise, I won't comment, but the more the merrier I say!
3. Colours
Things out-of-camera are warmer. Nikon produce slightly colder exposures. Nothing PP won't fix but for some JPG shooters, this may be of significance. Note, I don't have a set of grey cards. I use the shunned auto-WB feature. Shock horror!
4. Menu system
When I first shifted from a D90 to a 5Dc, I hated the outdated menu system. To put things into perspective, I had gone from 2008/9 technology to 2005 circ technology. Not rocket science that the UI would significantly be worse. At first, I couldn't stand the weird embedded menu structure found on the 5Dc, and subsequently got a 5DMKII quick smart.
Fast forward a few months and a switch back to Nikon, I now miss the simple nature of the custom fuctions. Ironic? Indeed. I now find the Nikon menu system way too categorised, and in a way that is not logical to me. Weird? Hell yea!
5. L ... L is for ...
What can I say? It could be nothing more than marketing but L-lenses rock.
6. Positioning of the exposure lock button
Simply put, I can reach the AE lock button on the 5D and 1D series with my thumb with ease. With the D700, I have to stretch my thumb. YMMV.
Now, this is what I like about Nikon (WRT D700).
1. CLS
To put this into perspective, until I owned the 580EXII, I hated the way my 5D and 5Dii interacted with the 480EX. I could not get the two to play nice. I had to do change a custom function so that the 5D/5Dii would know that a flash had been mounted and would do the right thing in Av-mode. Come the 580EXII, external lighting was a breeze.
However, I do think Nikon do have an edge with iTTL compared to ETTL.
2. D700 feels much more sturdier than 5D/5Dii
This is personal opinion only. I find that the 5D and 5Dii were toy-like. And the cheesy shooting-priority mode dial makes things even worse. I really like the 1D's implementation of changing program modes.
I dropped my 5Dii from hip height. My fault entirely but the resultant damage was pretty ghastly. For some reason, I feel as though the D700 would come out better if dropped and/or blended. I'm not willing to test that theory out just yet.
3. Auto-ISO
A lot of photographers, hobbyists and pros will cringe at auto-ISO. I use auto-ISO where possible. The 5D obviously didn't have it, nor did the 1DMKiii or 1DsMKii, but the 5Dii did. I can't speak for the 1DMKiv but from my experience of the 5Dii, the auto-ISO system of Canon is a bit weird. It tends to go for the highest ISO possible, rather than the minimum. Please not that I am not commenting on high-ISO noise quality. I am purely critiquing the method of how auto-ISO is applied.
4. Choosing AF points and their reliability
Once again, my initial reservations of Canon's AF points were marred by my switch from a crop D90 to a FF 5D (didn't grasp the clustered AF points of FF). I loathed how it was a chore to switch between AF points with the 5D. I resented the fact that all but the centre AF was reliable. However, I'm glad I started to rely on the centre AF point as I still do that to this day, regardless of which body and system I'm using. I still think with the D700, that selecting the desired AF point is easier with the D-pad. Once again, YMMV.
