I've been uncertain about my Canon 17-40mm f/4 lens for some time. Even before I purchased the fancy glass I'd read several reports that products were shipping in less-than-perfect condition and required factory calibration. I decided that I'd order anyway, hoping Canon had resolved the issue. Since I began use of the lens it just didn't seem right. Looking at Sunday's photos from Brandywine Gorge reinforced my doubts. Test photos today proved the flaw: the lens doesn't form sharp images! Proof came in the form of a series of test images I made with the camera on a tripod: manual focus, automatic focus; 17mm, 40mm; wide-open, stopped-down. In every case the recorded images were only fair at best when examined closely on the computer screen.
Visiting Canon USA's Web site I was hard-pressed to find how to receive warranty service. Finally I found that if I registered with the site, I could then get email support. Making my complaint and request for help online, I received a response within a couple of hours inviting me to return the lens to Canon for calibration. Good handling of my situation so far! The lens ships out tomorrow.
I can hardly wait for return of the lens tuned to its optimal state; it's a beautiful piece of equipment and should create excellent pictures!
I stayed up too late last night hosting a Public Night at the Observatory. Could have used more sleep. Sunday dawned cool and beautiful. It was a good day for a hike so we decided to head down to Brandywine Falls and the Gorge Trail there, a beautiful place inside the Cuyahoga Valley National Park, northeast from Peninsula.
I shot a good number of photos and was disappointed with a great many of them. They look pretty good at smaller size but enlargements show focus problems. It looks like my fancy Canon 17-40mm, f/4, L-series lens may suffer from a deficiency I read about in reviews of that product.
The lens is too expensive to let this flaw go uncorrected so now I'll need to figure out just what to do. Maybe first some more testing.
We had a very pleasant hike, it was just challenging enough (1.1 miles, says the GPS, with one very steep climb near the end), and a nice evening at home — the film Trekkies 2 is recommended! Back to work tomorrow.
We're holding our breath waiting to see what will happen at our fine institution when state funding details become established and known. Painful cuts are expected.
The trees will grow, the waters flow, the stars will shine, and life will go on. Goodnight!
PowerShot dinner? Sounds like I had my fill of whiskey or something. No, I had a quick meal at Taco Bell then headed to the Bay Village / Westlake border where there are some interesting buildings and railroad tracks. I thought that might be a nice spot to shoot a few more test images to get familiar with the little Canon PowerShot A650 and check out the results.
The settings selected by the camera appear very, very strange to me but here's what the camera displays for each image: For the building (above) we have an ISO of 80, 1/1250 sec., f/4.5. Huh? I'll verify in the EXIF when I get a chance. For the weathered paint in the photo below, it's the same! The images seem well exposed but I'd have selected for a slower shutter speed and a higher f-stop in this case. I'll be making adjustments soon.
Crazy sounding settings or not, the pictures are very sharp at full size and have good color with and without minor adjustments in The GIMP. Exposures are very good as well, showing excellent tonal range and shadow detail.
So, once I get the A650 dialed in to my preferences, I think it will probably travel with me quite often.
She Who Must Be Obeyed recently purchased a dandy new camera in the Panasonic Lumix line — a series of digital wonders that have Leica glass in them and produce excellent photos. That meant she no longer needed her Canon PowerShot A650 IS and she's letting me have it. I must say it will have to do a truly excellent job to make me want to replace my old Fuji FinePix S7000. Then again, the A650 is quite a bit smaller than the FinePix and I can more easily take it with me more places. So I'm giving it a go.
Just to get a feel for it I shot a few pictures of Tasha on her cat tree perch watching birds. There's apparently a robin's nest in the shrubbery beneath the window and the cat is tracking the birds' comings and goings.
I'm not used to cameras making all settings automatically, including ISO, but I haven't turned that feature off just yet. For this picture, recorded in dim early morning light, the camera shot at ISO 640, 1/60 sec., at f/2.8. Focal length is quite short so vertical lines are distorted and close inspection reveals quite a lot of digital noise in the image. Overall the picture isn't as sharp as I'd like, perhaps because the aperture is wide open.
I think I'll carry it around today and see how it goes. I know it's better than my cell phone camera and it's better than none at all for those times when you wish you had a camera.
Today we decided to try out the Salt Run Trail in the Virginia Kendall area of the Cuyahoga Valley National Park. It's just outside the town of Peninsula and we've visited that area often but never tried that trail. Park materials said it was "moderate to difficult" hiking and they were not fooling. The warm, humid air quickly brought out the sweat in us as we hiked rolling to hilly forest pathway covering a little over three miles. Along the way we stopped to photograph plants and animals we encountered, shooing away far more mosquitoes than I would have liked to have dealt with… including one little biter who actually tried to enter my ear canal! I swear, I didn't mean to kill it… it was an accident! I saw my first scarlet tanager (bird) and, at the end of the walk, we had a close encounter with a beaver that was gathering reeds on the banks of a stream. The hike was a lot of work but the exercise was good, the woods were beautiful, and the wildlife surprises a treat.
We sighted this great spangled fritillary butterfly visiting flowers in a prairie area of the park. It moved between plants at just slow enough pace to allow me some photo opportunities.
I don't believe I've ever seen a scarlet tanager before. This one was very shy … I had to hide behind trees and brush to simply look at the beauty. The best images were captured with the bird in shadow where, apparently, it was most comfortable — very difficult conditions for photography, however. Four frames exposed at long distance and that was it… off, deeper into the forest, it went!
As we were emerging from the woods, finishing our hike, we crossed an automotive bridge spanning a stream. There, to my surprise, was a large, deep brown beaver gathering reeds from the bank. It finished its work, slipped into the water, and swam under the bridge with a bunch of green plants trailing from its mouth. I couldn't think of an appropriate pun based on the old TV series, so let's just say we'll Leave It to Beaver.
We had a very nice, quiet Fourth of July. After sleeping in –a rare pleasure for this sleep-deprived fellow– we headed out for a four-mile hike on the Cuyahoga Valley National Park's Boston Run Trail. It's a woodland trail with paths ranging from packed earth to river gravel surface and terrain from rolling to hilly. Though it was a cool morning, the climbs quickly warmed us and we covered, probably, four miles. The photographic highlight came as we crossed a wooden footbridge over a quiet stream. There, flitting amongst the plants, were several damselflies. The lace-winged beauties alighted on green leaves, sat for a while near each other, then zipped off in singles or pairs possibly in a mating dance. This gave us many opportunities to photograph them. The "one that got away" was a beauty bearing a green iridescent abdomen. My photos just were not clear enough to show. I think the floater in my right eye is interfering with my manual focus and I can't trust the camera's auto-focus in situations like these: razor-thin depth of focus with sharp-edged objects surrounding the actual subject. The hike began under mostly clear, intensely-blue skies but when we emerged from the forest the sky was mostly cloudy.
After lunch at Burger King (a pretty fair BK Veggie) and a stop at PetSmart to stock up on canned food for Tasha, we headed home. Camera at hand, I shot a few photos in Her garden: flowers, a ladybug, and this tiny, really, really tiny, bee on the petal of an Asiatic Iris. For this kind of "wildlife" photography one needn't always go far.
She is making a dinner of veggie barbecued ribs (yes, it can be done), corn, and red, white, blue dessert (tapioca with strawberries and blueberries). I'll enjoy a glass or two of wine. Hoping for a fine, relaxing evening.
As a pleasant diversion (and out of curiosity) I left early for work Wednesday morning and made a trip out to Letha House Park in Medina County, the site of the Cuyahoga Astronomical Association's observatory. I wanted to see what progress had been made on the new driveway and parking lot for the park. I also figured I could enjoy a little nature walk around the pond and wetland area there, a little respite before the workday –and night– began. There was no progress on the lot except that a giant digging machine had been removed. The day was sunny and surprisingly hot. Walking slowly, dressed in shorts and tee shirt, I sweated as I moved along the path to the wildlife area. Dragonflies (yes, again) were everywhere so naturally I started shooting photos of them.
I also encountered a bird that flitted from perch to perch obviously trying to evade me but not wanting to go very far. I figured it was a mother and didn't want to tip me off about the location of her nest. Later I was able to confirm that it was a female red-winged blackbird. This particular bird was holding an insect in her beak, obviously a meal for her offspring, as I photographed her watching me.
Note: At home that night I found my camera no longer wished to talk to my PC. Haven't yet fixed it but I can do what many others do… offload the photos from Compact Flash using a media reader.
