Some shots from the backyard, today.

All shot with D300, 60mm f/2.8D, PK-13, SB-800, DIY small softbox, monopod. All are uncropped. All taken on the same small tree.


Mantis, probably Orthodera ministralis.


Katydid nymph, possibly Torbia viridissima.


Yellow-headed leafhopper nymph, Brunotartessus fulvus.

AJ ...... don't go outside as that last beast has his eye on you and looks dangerous ........... another fine set of macros

Nice macros but what is that insect in the last?

love the last one. cool little critter.
have you ever tried kenko tubes ? wondering why you paid the premium for the PK-13.

It is the nymph of a Yellow-headed leafhopper, Brunotartessus fulvus.

The adult looks like this:


Leafhoppers are related to cicadas and the adult does have a cicada look about it. The nymphs are the stages before adult, in between each moult. On the last moult, the adult emerges with wings.

I haven't tried them. I don't believe they existed when I bought the PK-13 back in 1993.

Interesting - I'm a bit of a bug fan myself ..
I really like to see the eyes so for me #1 seems a little soft. Love #2 - sharp as and nicely fills the frame with great legs. I'd like to see more of the bug detail in #3 so maybe a tighter crop . Nice use of light - can I ask DOF used ?
Great variety of bugs - I'm stuck with wooly aphids eating my roses at the moment so youv'e encouraged me to take an post a few shots.

Here you go:



As the nymph is so small, the only way to get it larger in the frame (without buying a longer tube) is to crop it. This guy is only 3-4mm long. The width covered by the whole frame is only 15mm (RR=1.6:1).

DebT wrote:Nice use of light - can I ask DOF used ?

You can ask. I'm not sure how I can answer on the specific DOF. I can tell you the lens was manually set on f/16 (the tube is manual and designed for AI lenses). To that there are two things to be considered to determine the effective f/stop: 1) extension caused by focusing the lens to its closest distance: 2) extension from the tube itself.

For the 1st one, with the lens mounted directly on the camera, f/32 becomes f/57 at full extension, which is about 1.5 stops, so the lens was effectively f/29. I'm not sure how much effect the tube (27.5mm) has on the f/stop, but I'm guessing at least half a stop. At a guess, I'd say the effective f/stop was between f/32 and f/45.

How this translates to DOF is anyone's guess.

I'll have a go...
the foremost foot on the nymph is just losing focus, as is the tail. Now you say the insect is 3-4mm long, but the tail is curled up (Not sure if length is counted using this pose, or stretched out) so DOF~= 3mm (+1 -0.5mm)

Andrew -
thanks for the blow up ..facinating little thing you sure have interesting bugs ..and now I know the size i can see why full frame was a huge job
The detail of you explination was appreciated and took quite some time to digest but (apart from learning I should ask the question differently next time ie what fstop) I think I understand and got the info I was after ...

Mr Darcy - thanks for the simple english translation

Think I am looking for the secret receipe for setting the correct fstop to get full subject focus with macro ...I don't seem to be getting the DOF preview working with macro particularily well ..is that to be expected or do I need to re-read the manual
Using 40D with Canon 100m 2.8 macro and X25 extension tube
