Hi, going to the Grand Canyon in July and looking to capture some great memories. I have a Canon 760D with the following lens. Canon EFS 18-85 mm 3.5 IS, Canon EF 70-200 4, and a Canon EF 50 mm 1.8. Do you think I need a Prime wide angle lens, or any other lens that may work better than my current outfit.
The equipment you have is just fine. Just add a tripod and you're set. I live a two hour drive from the Grand Canyon and have photographed the Canyon dozen's of time. I have used a Canon 7D and Canon 5DMkiii frame and on both, my Canon 24-105 f.4 lens which is more than adequate.
My suggestion for where to shoot in the Canyon is as follows: Arrive there approximately 3 to 4 hours before sunset. Proceed to Desert View, the east side of the Canyon. There is a sign directing you to Desert View as you enter on the main road. There are several turn off's on the way to Desert View. Go directly to Desert View first. When you finish there, you can start back on the road that took you there and start taking the turn offs as you head back to the main road. Each turn off is unique in itself and will present different views of the Canyon to photograph. As you get near the road you came in on, you will see wildlife and people stopped to photograph them. This is where your telephoto lens will come in handy. I am attaching a photo of the Canyon at Desert View. This was taken with the Canon 7D and 25-105 f4. lens. If you have any further questions, just ask me and I would be glad to help you. Roger
