Taken today at Muscatatuck NWR. This small snake was hanging out in a tree next to the marsh. I had to stack 1.4 and 2x extenders to get a decent scale. Still cropped 50%. The first time in a while I wished I'd had a shorter lens.

It was pointed out to me by a summer student who is studying snakes!

1D2, 500 f4 IS, 1.4x II + 2x II, ISO400, 1/100 @ f8, tripod

Here it is with some selective sharpening. The extension tube is an interesting idea. How much minimum focus could I expect?

I like the peeking out of the leaves pose. The slight softness is likely from the stacked converters. Carrying an extension tube would take up little space but help you out in a situation like this, giving you a closer min focusing distance. Thanks for sharing.

..stacking and shooting at a 1/100 is not a good combination !!!! Would have raised the ISO in a heartbeat!!!! at 800 looks great and over is totally usable!!!!

Reposts looks lots sharper and it is a great image!!! Love the intent look!!!

Repost looks sharper. I am not sure how much closer you get with the extension tubes but there are diff sizes-someone else may have the specifics. You can easiliy go to ISO 800 for a shot like this for more steadiness with stacked converters. While your camera said you were at f/8, it did not read the 1.4TC so you were really @f/11. You will increase sharpness by going to effective f/13-f/16 with stacked TCs

Alfred, some questions concerning use of the extension tubes.

Does the use of one extension tube require manual focus? Auto focus is important to me due to aging eyes.

On what lens are you stacking 3 and getting full frame Dragonflies?

Will the use of extenders affect SS / f stop?

Should I take my questions to the photography forum?

Thanks

Would be the best place to have a full explanation!!!! The Af is not possible but not a problem You can go past the focus point bring it back and press the shutter at the beep (that is my technique for manual)

You do loose light but in Av will be compensated!!! I stack 3 on both my 500 and 600 With the 600 and 1.4 will be difficult to get a dragon full frame!!! I like the 500 better since it has a closer focus than the 600!!!

Any questions just ask!!! Glad to help!!!

Apart from the slight softness already mentioned, this is a fine shot Dan. Love the almost ghost-like peeking out of the foliage pose you captured.
