I don’t usually like to discuss gear on this blog, but once in a while I think there are some things new or interesting enough to talk about, particularly when I think they may be critical for producing the best possible results. I have been wanting to test and compare the 2 latest Canon teleconverters (Canon Extender EF 1.4X III, Canon Extender EF 2X III) in a head to head test for sometime and this past weekend found me with an opportunity to do so. To be clear, this was not the optimal situation to make this test. The light was poor and the subject was probably too far away and not covering enough pixels to make a relevant comparison. But, I thought I’d give it a try.

These tests were setup as equally, but not scientifically, as possible. For these first two images, I processed as normal and tried my best to be equal in all capture and processing steps. I cropped to make the bird approximately the same size in both images, so obviously, the photo made with the 1.4X tc was enlarged more than the one made with the 2X tc. I then resized each to make them 1000 pixels on the horizontal. The purpose here was to see if there is a discernible difference in sharpness and image quality between the two. The 2X tc often gets poor reviews, but just as often gets raves by those who claim to know what they’re doing. Many claim that the better results are made by using a 1.4X tc, or native lens and cropping in post to obtain better results than those obtained by using the 2X tc for an optical zoom.

Open the two images above in separate tabs to see a roughly equal comparison. In my opinion, I was pretty pleased with the results of the 2X tc in sub-optimal conditions. Both photos are fine for sharing on the web, although the IQ would limit print size. Like I said, the conditions were poor and the bird at a great distance. However, I think I would give a slight edge to the photo made with the 2X converter. This edge might just as well be due to differences in how I processed or with changing conditions within the few minutes between captured images.

Let’s look next at the “100% crops” of both photos. This simply means that these photos were both cropped at the same dimensions (4″ x 6″) and not resized. These examples were NOT sharpened.

Focal length equivalent = 500 x 1.6 x 2.0 = 1,600mm

 

Focal length equivalent = 500 x 1.6 x 1.4 = 1,120mm

Again, with this comparison, I find the two very close. Either one would work well enough, but if your goal was to maximize print/display size, I would probably go with the 2X tc. I guess this has surprised me a bit. I was expecting that, under these sub-optimal conditions, the 2x tc would fall behind the supposedly sharper combination of the 500mm + 1.4X tc.

What do you think? Did I make any major blunders in my comparison or analysis? Please let me know. I do hope to make this comparison again under perfect light and optimally placed subject sometime in the future.

Thanks for stopping by and reading this far!

Having some success with SEOW

Short-eared Owl

Miguel and I have been trying to get some better in-flight shots of the Short-eared Owls that use the wet prairies at BK Leach CA for their winter homes. Tonight, preparations and fortune came together and we wound up with a few that we can be satisfied with. The lighting wasn’t great, as the nice sunlight was blocked by heavier and heavier clouds as soon as the action began, but sometimes you take what you can get.

Birding the not-so-windy city

Piping Plover – Captive bird held at the Lincoln Park Zoo

A few of us headed up to Montrose Harbor on the north side of Chicago yesterday in search of a rare and late shorebird visitor. There has been a Piping Plover that has intermittently been using the beaches here since October. We visited following approximately four straight days that the bird was sighted and the weather forecast was great for this time of year. Unfortunately, the bird was a no-show for us on this day. Since the Lincoln Park Zoo was almost directly across the street, we checked to see if they had a Piping Plover in their collection. This is the female bird in winter plumage pictured above.

The harbor held a decent number of waterfowl that we were able to get close enough for some shots. See below.

WGNSS Nature Photography Group Visits Loess Bluff NWR – November 2018

Snow drops

Seven of us made the long drive to our destination on the morning of the 23rd . The week of
Thanksgiving can be an excellent choice for visiting Loess Bluff NWR, but always depends on the
weather. We were a bit concerned with the early cold snap our region experienced this autumn.
However, in the week or so preceding the trip, the weather warmed so we were not hampered by ice
that can completely cover the shallow waters of the wetlands. Having open water affords very close
views of our photographic subjects and the primary reason we drove such a distance – the blizzard.

The blizzard

Typically, one million to two million Snow Geese will make this location a stop over during spring
and autumn migration and numbers of over 500,000 birds on a single count are not uncommon.
During our visit, the official counts were slightly over 100,000 birds, but the feeling with the group
was that this was grossly underestimated.

Rising snow

If conditions allow, getting the moon behind the Snow Geese can make a nice composition.

Lunar Liberty

On our first day of the trip we were faced with mostly cloudy weather. As I told the group, this provides an opportunity to more easily try panning motion shots like the one pictured below. This is not my most successful attempt at such an image, but I wanted to share it here to demonstrate the multitude of opportunities for a diversity of photos to be made.

Panning with the action

Snow Geese are not the only subjects that make this trip worthwhile. The refuge also provides
important habitat for birds such as Bald Eagles, sparrows, a variety of ducks and wading birds, as
well as mammals like white-tailed deer and muskrats. On our initial entry to the park, Dave and Bill
found a Merlin on a relatively good perch above the road. We spent some time photographing the
bird, but regretted that the rest off our party were on the other side of the refuge and would not
likely be able to get the looks we did. Fortunately, a Merlin – likely the same bird, was spotted on
our second day and was viewable by all.

Merlin

With subjects in the hundreds of thousands to the millions, making a purposeful image can be challenging. It is quite natural to want to shoot at everything that moves, but try and focus. Finding smaller action scenes is one way the photographer can focus on the individuals and their stories that make up the grander scheme.

Goosing a goose

Although we experienced skies with periods of heavy overcast, we were presented with fantastic
sunsets on both days. Being able to make the birds part of the story made these images all the more special.

A beautiful end

The WGNSS Photo Group is committed to an overnight trip to this and similar locations within the Midwest on Thanksgiving week. If you’d like to join us next year, please let me know!

White-tailed Deer

Something is in the air

Until this autumn, I never considered targeting our abundant white-tailed deer as a photo subject. When my friend, Miguel, brought up the idea along with a place with a lot of potential, I asked him to lead the way. We set up in a copse of trees located near the center of a scrub field in an area that does not allow hunting and Miguel’s predictions of worry-free males still on the hunt came to fruition.

Buck and Foxtail

Although I cam ill-prepared, leaving my tripod and any other means of support at home, the light was just sweet enough to allow for proper hand-holding the big 500mm. Once I took off the unnecessary teleconverter, it worked even better.

Spike

We counted at least two larger bucks that patrolled the area, but found this young spike buck as well. He was not quite as confident as the other two.

Doe

Females walked the area as well, but were more skittish. The bucks were more curious when they first heard the sounds of our shutters slapping and picked up our sent in the light morning breeze. The does, however, tended to trot away at first sign that something different lurked in our copse.

White-tailed Deer

This spot turned out to be quite nice. With the rising sun to our backs, the trees at the far edge of the field provides for a nice backdrop for that warm light to hit against. These guys have probably, or will soon be dropping these nice racks. With any luck we can try more of this next year.

Thanks for paying a visit!

A Backyard First!

Red-breasted Nuthatch

I’m so glad I spent some time at home this afternoon. This gave me the opportunity to find the first Red-breasted Nuthatch that I have found visiting our backyard feeders. I so wanted to some how tell this little one that I would have seed available all winter long as it consistently went back and forth from the big oak to the feeder, each time carrying a sunflower seed to hide in the bark. I am pretty certain that this bird visited the feeder more than 50 times in the couple hours I watched.

Making the Birds Earn their Supper

White-breasted Nuthatch

I have been given a lot inspiration lately by a number of Facebook friends to photograph the great birds that visit our feeders, or to put it another way, make these models work for their supper. On a recent birding trip, Sarah and I collected some great drift wood that I turned into horizontal and vertical branches in the backyard, not too far from the feeders and our sun-porch.

Dark-eyed Junco

I drilled a few extra holes towards the rear of some of these to act as unseen cavities to place my homemade bark butter. It only took the Juncos a couple of hours to find their favorite food. These guys go crazy trying to figure out how to get to this stuff. I made sure to place a few feeding spots near horizontal perches that they could access without too much difficulty as they cannot grasp vertical perches very well. These guys are so tame that they were my primary subjects, other species being a little more timid to visit the close perches and seed deposits that I sat close to.

Dark-eyed Junco

For a first attempt, I’m pretty pleased. These were shot hand-held in mixed lighting with my 100-400 mm lens and I shot through the not-so clean windows of the sun-porch. I tried sitting behind the open windows, but this must have made me much more conspicuous. I sat for an hour or more with few birds coming in to feed. Within seconds of me closing the windows, the Juncos came to the feeding stations.

Downy Woodpecker

I’m a little concerned that my resident Downy Woodpeckers might have a little too much of the rich food I am providing. They now have access to the peanut and tree nuts in the no-mess mix I provide, beef tallow suet blocks, and now the bark butter. But, I suppose it would take a lot for a wild bird to over indulge.

Anyone who feeds their wild birds and has an interest and access to photography should give this a try. I’m looking forward to more cold mornings spent outside trying my hand at this.
