p.1 #1 · p.1 #1 · Ants with the Medical-Nikkor


Now that we're finally getting some sort of warm weather I decided forget work for an hour or two and take my Nikon Medical-Nikkor.C AUTO 200mm f/5.6 out for some field work.

I have the LD-1 DC Power unit which allows me to use the built in ring flash untethered from a power outlet. Of course with the help of 8 D batteries which normally would be heavy but I have AA to D adapters that lets me use my Eneloops.

Using this lens is hard since ants move and there is no focus ring what so ever, so I have to constantly move. However I figured I'd use the good old trick of focusing on one spot and then snapping the picture when they stepped into it.

Here are the best:

#1


#2


#3 - Put a dime next to them so you can see scale and because it made them pause to inspect


#4


#5 - Accidentally moved the ratio ring so it imprinted the 3x (3:1 life-size reproduction ratio) on the image.

Good series.
It's a fixed focus lens ?

Nothing compared to your stuff.

Yes it is fixed focus.

The shots above are all at 3:1 which means I have to attach the 1x & 2x auxiliary lenses and be exactly 2.83in from the subject. If I wanted to do 2:1 I'd have to attach the 2x auxiliary lens and be 4.25in from the subject.

It's almost like the MP-E except there is no zoom, instead there are 6 auxiliary lenses (diopters) and a built in ring flash. It's very challenging on moving subjects. This lens was originally for dental work.

Also my shutter speed MUST be at 1/250 (Flash Sync) and my ISO MUST be at 100 ISO in order for the built in ring flash to properly expose the image for 3:1. This is all calculated on the lens which also sets my aperture to f/45 for that combination.

On another note I realize my sensor needs a cleaning but the D3 is a dust magnet and at f/45 and being that close to the dirt, it's going to be dirty.
