Weekly photo, 11 May 2014

This week i finally photographed some Frogs, it was about time ! Not many Frogs yet, in one of my regular pond i found only 3 Green Frogs that morning but i managed to get a couple of good shots.

I was at water’s level to get that view, the tip of the lens hood was in the water. Canon 7D with Tamron 90mm Macro VC handheld.

P.O.V. when photographing Frogs.

When i’m photographing Frogs i always try to have the best point of view (POV) to show them at their best, it’s not always easy since they are small, so you need to get low and be ready to get dirty. The lower to their level you can get the best they will look on your final shot. Another benefit is that usually the background will look better when shooting low, that is if the background behind the from is not too distracting and select an aperture that will blur it.

Here is an example i took this morning, same Green Frog, both taken with 7D and Tamron 90mm Macro VC at f/5.6:

For this one i was on my knees and looking through the VF to compose the shot.

I switched to LV and put the camera as close to the ground as i could and tried to compose the best i could without falling into the pond !

I prefer the second photo because the Frog look better because the POV give it more pride. I nearly fell into the pond to get that second shot, the shore was steep and muddy and when i tried to get up my boots were just slipping on that muddy terrain ! As i was fighting to get up the slope the Frog never moved, it was probably waiting to see if i would fell into the pond to have a good laugh at me 🙂

For this photo of a young Bullfrog it was a different story, it was on a Moss covered branch at a good distance from me. The challenge here was to position my tripod mounted camera with a 400mm and 64mm of Extension tubes in a pile of branches to get the view i wanted. I would have liked to get lower to clear the branch in the background but i couldn’t get low enough and still get a good view, so i set the lens W/O at f/5.6 to blur the background as much as i could and did some burning in PP.

Those photos were all taken this morning at a local pond, it’s a great place to photograph different species of Frogs in a beautiful habitat and also Snapping Turtles. It offers a variety of backgrounds and mossy rocks and branches, i just need to look around and find the forg with a better surrounding that will make a great shot and reminds to get low.


Canon 70-300mm IS, my impressions.

I wanted a telephoto zoom lens to go along  my 400mm/5.6 L and 7D. I didn’t want to spend too much because my goal is to buy a 70-300mm IS L or wait to see if Pentax would come out with the 135-400mm WR that was on the roadmap. It’s a lens that will be used in vacation or when i don’t need or want to carry my 400mm lens. I read many reviews and user opinions before i finally bought one when a store here in Canada was selling brand new ones for 420$ . I could also have bought the 70-200mm/4 L as it was 600$ (i already own a TC-1.4XII), but i wanted to have a lens with IS.

The built quality is cheaper than my 400mm/5.6L and all my Pentax lenses (i don’t own cheap lenses for my Pentax cameras). I was aware of this before buying it, so not a problem. The focusing ring is not the best i’ve used and MF with LV is manageable at best.

100% crop of the shot above with PP in Photoshop and sharpening applied (amount around 95 and radius at 1). You can see some CA in the highlights.

One of the reason i bought that lens was to photograph frogs which would need the use of Extension tubes on some occasions. At 300mm with extension tubes the sharpness is quite good , not as good as a Macro lens but good enough for publishing photos in a magazine. At shorter focal length the IQ is quite good, but with extension tubes and zoomed out from 200mm to 300mm the set-up is not very rigid and is prone to vibration so you need a solid tripod, i also use LV to focus and 2 second delay with a remote release.

I’m lucky to have a young Cottontail Rabbit that likes to live in my backyard and he have a favorite spot just in front of a black spruce where it’s well hidden from predators. He’s now quite accustomed to see us in the backyard and i can get close to him with my camera and he even sleep when i’m close to him!

Here it is looking at me, below are crops from that shot, i was also trying Spot AF.

Zoomed to 100% with no PP and no NR.

With some PP, sharpening in PS7 (Amount 89, Radius 1.0).

From what i’ve shot with that lens up to now it reflects what i’ve read on some reviews and user reviews, it’s quite good up to 200mm when stopped down 1 stop, at 300mm IQ drops but by stopping down to f/7.1 IQ is relatively good, not up to a prime lens.

This shot was taken near the minimum focusing distance of the lens using LV at 10X magnification.

This is a 100% crop of the previous shot.

A shot taken at “normal” distance, more standard use of the lens.

7D, lens set at 90mm, ISO 100, 1/50 sec. at f/10, tripod.

Sure it’s not as sharp as a prime lens at longer focal lengths but when stopped down it can produce very good photos until i can buy the 70-300mm IS L ! I’m now getting to know that lens and use it more often for photographing frogs and it’s doing very well. For the price i paid it’s a good value even if the built quality could be better especially the focusing ring that could have a better feeling. I wish that Canon would give at least the lens hood with their lenses like Pentax do.


Pentax DA14mm/2.8 for close-up photography

The Pentax DA14mm is the 14mm lens that have the closest minimum focusing distance on the market (correct me if i’m wrong). It’s a great lens to show a flower, mushroom or a frog in it’s environment by getting close and frame your subject with a background that will enhance it. It takes some practice to get the most out of that lens at close range, the lens hood can nearly touch your subject at the minimum focusing distance and also cast shadows. When i’m photographing that close i now remove the lens hood, especially when photographing frogs.

With the Shake Reduction of my K20D i can handheld that combo to take photos of subjects close to the ground or in situation when it’s hard to position a tripod. In some occasions i was holding my camera in one hand trying to photograph a frog while keeping my balance on the shore of the pond, the frog was certainly laughing at me !

The image quality of that lens is very good but the corners are not as good, so don’t put important elements in the extreme corners of the frame. The only thing i wish is that Pentax would update it as a WR lens !

This photo of a Green Frog was taken on a sunny morning on a small pond, the frog was lit by the sun and the contrast was too high with the surrounding vegetation for my taste. I took off my shirt and hang it up on some cattails to shade my subject and it’s environment.

When i  found this Stemless Lady’s-Slipper (white specimen, habitually they are pink) i knew i wanted to show that beautiful flower in it’s environment, so i choose my DA14mm for the shot. I was lying on my stomach on the ground and use the help of SR to steady the camera.
