First macro shot with D300

Here is the first shot I took with my D300 and the pancake 50mm MF AIS lens with an extension tube:


As one can see, about 19 mm of the ruler fits onto the sensor of the D300. Given that the D300 sensor is 23.6mm wide, the macro setup produces a 1.24:1 ratio. It is better than the 105mm macro lenses but obviously, I'd have to get pretty darn close to a subject with the 50mm, in fact, about 10 cm, a tiny bit too short for live insects.

Here is my D300 fitted with the 50mm attached to a simple extension tube. The extension tube has no electronic contacts.

Macro photography

Well, I was not planning to do any shooting today although the idea of another hiking trip was very appealing in this 25C temperature, but a buzzing noise was hovering over to my right in my bedroom. The last time I heard that buzzing was from a wasp that managed its way into my room a few weeks ago. I wondered where it came from. Well, today, I see two of them. I think there is a hole in my new window frame and their nest is somewhere close, very close.

Anyways, I decided to test the macro capability of my Vivitar 70-210mm. Alone, it can produce 1:2.2 real life ratio. Added the 2x teleconverter I have, I can whip up a near real life macro shot, at 1:1.1. I took a few shots of the wasp but I had set the shutter speed too slow at 1/10 secs so the pictures turned out a little blurry. I did however get a couple of shots at 1/320 secs. I also tested my 50mm lens with one 50mm extension tube to take a few shots of the wasp.

The first four shots are from the Nikkor 50mm. The last two on the right are from the Vivitar 70-210mm. The original photos have been resized to 1024x685 but they are not cropped so what we see here is what filled the sensor screen. With either lens, you have to get to about 10 cm of the subject. It was a little unnerving to get so close to a wasp (as I had been stung once) but this one was very gentle.

For these shots, I had to use the external speedlight set on Manual mode as the built-in flash is too low -- the Vivitar lens is almost a foot long. In Manual mode, the speedlight does not talk with the camera so it was a little painful trying to figure out the right setting without a light meter. I wish I had a D300 or one of the other professional DSLRs that can meter with the manual lenses. I had to take a few shots and adjusting power output level of the fash, before getting the right exposure.

The lens aperture was set between f/8 and f/22. The speedlight was set somewhere between 1/128 to 1/1 depending on the shutter speed I used.

For most of the shots at f/16 or f/22, the power output from the flash was set to 1/1. I just cannot remember which photos were shot at minimum aperture but the last two photos were shot at f/16.

So, which lens do I prefer for macro photography? I have to say, the old 1975 Vivitar lens was easier to use. At whatever aperture I dialed, you could still view the subject clearly in the viewfinder -- the Vivitar lens is a bigger, wider lens than the 50mm so at f/22 the Vivitar aperture is the same size as the Nikkor 50mm lens at f/8. That is, the Vivitar can gather a vast amount of light even at f/22. With the Nikkor 50mm, without background light, it may be impossible to see what you are shooting. So, for this reason, I prefer the Vivitar and while I had the intention to sell it because I hardly ever used it, I will keep it for macro photography now.
