Didnâ€™t really show the excellent focusing that was obtained yesterday at the Zoo â€“ here is an example. Using the 18/200 yesterday I could only get so close to the subjects â€“ this monkey was sitting on a stump quite a way from us as we drove by on the main road. The landscape shot is the one I took at 187 mm zoom ( the 7D has a 1.6 sensor = 300 mm equivalent ) and cropped it to show the close-up of the monkey â€“ even at that amount of cropping I still have excellent sharpness. I love â€œBack Button Focusingâ€ .
Went with Pat to Khao Kheow Open Zoo near Chonburi yesterday morning to test my new camera setup. I am amazed at the quality of the images â€“ the 7D was set up using â€œback button focusingâ€ and evaluative exposure from the focusing area. â€“ Images are tack sharp at the set focus point and the histograms show almost perfect exposure.
Most were shot from the seat of a golf cart we had rented to drive around – hand held â€“ ISO 400 using a 18-200 Canon Zoom lens, camera set at â€œPâ€ mode auto. Many needed a lot of cropping because even with the 18/200 I couldn’t get close enough to fill the frame.. They also show the high ISO â€“ being a little grainy, but better than I was getting before.
