Here are my dominant opinions: ;-)
- They're both VERY high-quality lenses.
- 24 mm is a nice focal length for wide-angle shots.
- 17mm is a VERY wide angle on a full-frame camera. The extreme angle-of-view can be useful, but it can also pose some difficulties. For instance, it may be difficult to avoid capturing the legs of your tripod in the photo. Also, wide-angle distortion will be extreme. Rectangular objects like tennis courts or the top of a picnic table will morph into trapezoidal shapes.
- Polarizers don't work well with wide-angle lenses, and the light fall-off problem is even more extreme when you apply movements (rise, tilt, etc.).
- If you plan to photograph architectural interiors, the 17 mm lens would be a great choice. Otherwise, the 24 mm lens is a more versatile choice.
- Use a bubble level attachment to level your camera body for the best possible effect.
