Photo Tips #7 : Crop Factor Revisited

I talked about crop factor in the previous installment, it’s the reason why an identical lens mounted on a camera with a smaller sensor will appear to have a local focal length. I thought that a diagram might help clarify things further, so let’s try this. Imagine you’re looking straight down the lens onto the sensor, mounted at the back of your camera.

Photo Tips #6 : A Lens Primer (Part 1)

If you have a DSLR you have a choice of hundreds of different lenses, ranging in price from $50 to many thousands (the most expensive I ever saw was a Canon for $100,000 – used!). So how to choose? A lot of that comes down to personal preference and what you want the lens for, as well as factors like budget, but in this article I’ll try to give you a basic primer so you at least can understand the differences.

Photo Tips #5 : Canon’s Numbering Scheme

As a follow up to my DSLR guide, here’s a quick explanation of Canon’s DSLR numbering scheme which will hopefully clear up some common confusion!

All Canon DSLRs have a model number starting with 1, 2, 3 or 4 digits and ending in D. For example you have the 5D, the 60D and the 600D. Here’s how to tell what you’re looking at:

  • The fewer digits, the higher end the camera is. So a 1000D is basic, 500D is entry level, 50D is mid range and 5D is pro.
  • Except for the single-digit numbers, higher is newer. So the 40D replaced (and is better than) the 30D, which previously replaced the 20D.
  • For the single digit numbers, lower is better. The 5D is awesome, the 1D is the ultimate. Newer models in this range get suffixes, e.g. the 5D mkII.

I believe Nikon use a similar scheme (although I’m not a Nikon expert) but they put the D at the beginning!

Photo Tips #3 : Which Camera? (Part 3)

So far I’ve posted about Compact Cameras, Superzooms, and Micro Four Thirds. Now it’s onto the big boys – the DSLRs. This is what most people think of when they consider a serious or professional-style camera, and while the top end models are still priced for the Pro only, there are now many much more affordable options.
