One funny thing about White-Throated Kingfishers is that at times they can appear to be lost in a daydream. Hearing my whistle yesterday, my little friend put himself into position to watch me pass without me seeing him. But when I passed a point where he came into view, he was lost in his thoughts as I prepared for a shot. He realized I was there just before I pressed the shutter button, the resulting shot below.
The two RF fresnel lenses have been fantastic stop-gap options, but the RF 100-400mm has left me with little inclination to use either. A respected reviewer points out that the 600mm is a sharper and cheaper choice than the 100-400mm + 1.4X.
Not entirely true.
Yes, on subject matter where fine details have plenty of contrast (small lettering on a distant signboard, e.g.), the 600mm can render greater detail. But with bird feather details, it’s no match for the zoom, even with the TC attached. It reminds me a bit of the Nikon 300mm PF in that respect.
With the 800mm on an outing this morning, it occurred to me that in shooting position with the hood attached, it’s probably a good bit longer than the 100-500mm with extender. With the rainy season well under way, the non-retractable (with extender) zoom is starting to look like a possibility. That it can also shoot at close-up distance gives me pause for thought . . .
. . . again!
