Canon EOS 20D Lens Advice
Darren lists the lenses he uses on his Canon 20D. I’m very tempted by the 50mm f/1.8 as it has got some great reviews and is relatively cheap. Unfortunately with the 1.6 multiplier of the reduced size sensor in the 20D you’re left with the coverage of an equivalent 80mm lens. Maybe I should lock my lens at 50mm and shoot with that for a day to get the feel for that size.
What lenses do I own? Nothing outstanding, yet. Only consumer grade lenses so far:
- Canon 18-55 kit lens. Perfectly usable, lovely and light.
- Canon 75-300mm IS. Hell of a zoom at a good price. Tends to hunt when zoomed in, but manual focus fixes that.
- Sigma 18-200mm. Great general purpose zoom lens. I miss the image stabilizer of the 75-300mm especially as it’s quite slow at f3.5-f6.3.
* Slow here means that the lens doesn’t let in much light when zoomed fully, which in turn means that you need to take a longer exposure, resulting in shaky photos. The only way to alleviate this is by using a tripod, or increasing the ISO sensitivity of the sensor, but that causes noise.
Here’s a simple rule: always be sure that the exposure time is is 1/zoom seconds.
ie. If you have zoomed to 200mm then your exposure time should be at least 1/200 sec.
