D800 First Impressions – Part 1

I finally had a chance to shoot with my new D800 on Tuesday. (I decided to delay travel into the night so I could have some daylight.)  I was just glancing at some of the pics while on a call and found one that illustrates some characteristics of the D800.  I’ll post more next time about my general impressions of the camera, but this pic will answer a couple of important questions – at least for me.

This is a (female or juvenile) Black-Throated Green Warbler:

The technical details are:

JPG – Fine – L, FX crop (36.2MP).  300mm/2.8 AF-S VR, TC-20E III (600mm), F11, 1/200, ISO 3200, Distance 7.25’
LE NR – Norm, Picture Control – Standard, Active D-Lighting – Auto, JPG Comp. – Optimal Quality
Processing in Aperture:  Mild sharpening, added Definition and Vibrancy, slight White Balance, Exposure +0.5

There are two important things to notice here.  First is the incredible detail possible with this body.  The Warbler was quite gregarious and often came closer to me than I could focus!  I had to keep moving away from her, and had to switch from DX (my default birding configuration) to FX to fit her in the frame.  (What a great option to have available vs. the D300!)  BTW, the DOF at that distance is about 0.2”, or less than a quarter of an inch.  Check out the area around the eye.

Screen grab of 100% view in Aperture.

Another note:  The 300/2.8 VR I w/TC-20E III would not be considered a super sharp combination.  After realizing how poor it is wide open (F/5.6), I’ve started shooting at F/11 to at least get acceptable sharpness.  Still it’s nothing close to the 500/4 (on my wish list) or the 600/4.  Bottom line, this is not the best you can get out of the D800!

Second, notice the noise.  This is an ISO 3200 shot, with exposure pushed another 1/2 stop in post!  There was no noise reduction except for what may have been done in camera.  (Not sure if there was any…)

This is much cleaner than my D300 at 1600, and as good or better than my D700 at 3200!  Wow!  I may have found a replacement for both.  Unfortunately, that means I’ll likely end up buying another one so I can continue to have two bodies.

As I said, I’ll try to do another post ASAP to present other thoughts about the D800, including overall feel, battery life, frame rate, focusing speed, controls, and accessory costs.

The Down Side of Using a Car as a Blind

Snowy Egret

Snowy Egret

I’ve read a number of authors suggest the idea of using your automobile as a simple and effective blind for wildlife photography and I’ve gotten some shots I would have otherwise missed by doing it. The other day I learned that the idea is not without its own problems.

I was in Florida with only a little extra time before a flight and I was trying to grab a few shots of the incredibly numerous and varied birds there. It was therefore not only a handy form of camouflage, but also a practical necessity for me to stay in my car for some of the shots.

Here’s a 100% view of the full-frame Snowy Egret shot on top. It was my first shot after I pulled up to this spot so I was just grabbing something in case it spooked. The framing was poor and the highlights blown out, but it also wasn’t sharp. I was shooting RAW so I wasn’t too concerned about the highlights, and I was going to shoot some more to get the framing better, but I just couldn’t get the thing sharp. In fact it got worse and worse!!!

Eight shots later, here’s what I got (no adjustments of any kind on any photo on this page). I was rubbing my eyes trying to figure out why stuff was coming in and out of focus without me even touching my camera!

A great feature of shooting from within a car is the ease of finding sturdy stuff to rest your arms on, so I didn’t think I was having a camera shake problem. Seeing that my shutter speed was 1/3000 of a second, I knew that wasn’t the case, even at 500mm. And this wasn’t the look of camera motion.

I finally pulled back from the camera and looked at the scene. The whole thing was shimmering! The heat from the car was rising up right by the window I was shooting out of and ruining the view. That was then magnified by the lens. Because of the direction of the mild breeze I could have been shooting out of the passenger side and never had a problem. But on my side of the car, boy was it a problem!

So from then on I have kept in mind another consideration when shooting from the car. If the wind is blowing from the front or opposite side of the car, I need to get out to shoot or else the sharpness will be suboptimal.
