Last night after another magical slow cooked dinner we decided to have a fire. After we got the s’more pit going, I looked up and noticed a
gaggle pride flock band murder of crows. I know why they call them a murder.They make so much obscene noise you want to murder them all! It was a toss up between the camera and a gun on this “shoot”. 😉 My theory is that there was something dead nearby because they and two hawks kept swooping in and out of the trees behind our house. Anyways, it was golden light and everything was rich in colour. Love it! Can’t beat it ever! I grabbed the 70-300 and nabbed a few shots before the light slinked away behind the horizon. It’s gyp that the sunsets aren’t lasting as long as they did even a few weeks ago. All of these shots (except the fire pit) are with the 70-300. You can see how longer glass gives you added compression and photo num nums. The power/telephone poles show this in the pics of the family. Even at f/5.6 0r f/8, they look compressed and bokehlicious. 8) And the shots of the lone yellow clover blossoms have sweet sweet bokeh at 300mm. That’s the added benefits of compression in images. If you’ve ever wondered why the vast majority of portrait photographers use that magical 70-200 lens, this is why.
One of the gaping holes on the Internet was a comparison of the 70-200 f/2.8 VR lens and the 70-300 f/4.5-5.6 VR lens. Fortunately, I was able to borrow the f/2.8 glass and compare it with my 70-300. And, I made a YouTube video of it to share the goodness. Both lenses are great, but they are definitely for different tasks. If I was a wedding or concert photographer in low lighting conditions, I’d want the f/2.8. But it is one heavy piece of glass and in my opinion isn’t as desirable as a walk-around street lens. Enter the 70-300. It’s waaay slower than the 70-200 (autofocus and aperture) but it’s lighter and more balanced on DX camera bodies. But alas, it sucks in low light, and the auto focus hunts around like a blind hyena. Anyways, here’s the video. 🙂
Recently on an episode of Fro Knows Photo, I watched the Fro & Greg edit a RAW file of some girl posed in a sitting position on a concrete ledge with a forest type background. At the end of the show, they were critiquing the shot such that it had been taken with a 50mm f/1.8 Canon. The general gist of what was said was that the bokeh on the 50mm 1.8 was not as pleasing as it could have been had the portrait been taken with a 70-200mm f/2.8.
Now, I happen to love 50mm primes. They are almost the perfect portrait lens on crop censor cameras, producing a sweet 75mm on my D300s. In fact, my new 50mm f/1.4 G lens should be arriving any day now. So while I wait, I decided to borrow a 70-200 f/2.8 lens from Jocelyn, setup my own miniature wedding photo shoot for John & Marsha and do a “which has better bokeh” test. 😉
There are two main things going on that we need to be aware of: Bokeh & Compression. Bokeh is the Japanese word for “stuff that is out of focus in a photo.” Compression is described as an effect produced by a long lens (longer than 35mm) that smooshes and flattens backgrounds. It gives the effect of even more buttery bokeh. There are some people who contest this as a myth though.
For simplicity’s sake, longer telephoto lenses *should* produce more pleasing bokeh because it is “compressed” in addition to being out of focus. This is where Greg was coming from on the Fro episode. So, let’s check the results of my mini-field test and you can make up your own conclusions.
The situation was that John and Marsha surrounded by background and foreground elements (pineapple, spiderplant, gerbs and a happy face flower resting on two toddler chairs and a brick wall). This simulates a wedding couple in a park area with some trees & shrubs and thick forest behind them. The lenses used were Nikkor 70-200mm f/2.8 VR, 70-300mm f/4.5-5.6 VR, 105mm f/2.8 VR macro, and a 50mm f/1.8. All the lenses were mounted on a D300s on a tripod using mirror lock up and a cable release with VR off. Light levels and ISO remained constant. Distance was slightly changed to try and maintain similar perspective.
Here is a gallery of the results:
What do you think? Which lens has the most pleasing Bokeh? Which lens produces the most pleasing portrait? 🙂
