Change to canon from nikon?
I have a nikon d7000 with 50mm 1.4G lens and is the only lens I have.
I've been thinking of changing to a full frame canon or 7D as the lenses I find are cheaper than nikon and I know nikon lenses are better built. There are a few canon lenses I have in mind but when I compare the same lenses to nikon, nikon are double the price.
I'm also going to be doing a photography course in September and want to expand my variety of lenses with having to spend more than £500 on just one lens.
You're going to a photography class? First-time? I suggest you delay jumping ship. Stay with your D7000 and get a cheap secondhand 18-55mm AF-S VR for the class. After finishing the course, you should know better to decide whether to cross-over to Canon or stay with Nikon.
It is interesting that you seem to want to move from one camera system to another… A very costly choice
The other thing you do not know is that the Canon 7D is NOT a full frame camera and when compared to your D7000, the sensor of the 7D does not perform as well as your current D7000
If you want a full frame dSLR, then look at the Nikon D610 (it can use all your current Nikkor lenses)
If you look closer at the cost of Canon EF lenses (the ONLY ones that will work in a full frame Canon camera like the 6D) you will see that they too are rather expensive)
By the time you take the loss on selling your Nikon gear and then buy Canon gear to replace it, you could have invested in an excellent Nikkor lens or two.
Do the math. What can you sell your Nikon gear for and what will you be able to buy using that money and any money you have saved for Canon lenses. It will probably be less expensive just to buy the Nikkor glass you need and then later buy a full frame Nikon D610.
As far as Nikon glass costing twice what Canon glass costs, take a look at the two links below to Nikkor and Canon lenses. Yes, the costs are in US$, but you can see that it is rare that you will find a Nikkor lens costing twice what a matching Canon lens costs.
You have a fine camera. If you want to save some on lenses, get the f/1.8 instead of the f/1.4. Lots cheaper, just as sharp, and you and I can't tell the difference between f/1.8 and f/1.4. Besides, read this article:
