March dagger moth (detail)
Just having received my 2x teleconverter I went to the woods, eager to test the 2:1 magnification ratio. But being march, I could only see some ants and flies, till I spotted this moth. It made my day, and this photo showed the worth of the extra magnification.
The whole moth:

The March dagger moth is a moth of the subfamily Chimabachinae. It is found in Europe.
The wingspan is 19–29 mm. The moth flies in one generation from March to May depending on the location.
The larvae feed on various deciduous trees, such as birch and oak.

Main problem is the shallow DOF at this magnification. At times it is better to trade resolution/magnification for DOF. Future goal is to learn and apply focus stacking.
I choose a teleconverter because at 2:1 magnification the object distance is the same as 1:1 magnification without teleconverter. Being able to keep a distance is really beneficial in not scaring away the insects and keeping flash use easy.
Disadvantage of the teleconverter is image quality loss. Only above f/11 sharpness is good (as you can see). The f/11+ aperture means I need a flash and am limited to macro distances.
When I go out to photograph I will only put on the teleconverter when the situation asks for it. But then I am able to take pictures which I would have never been able to take without the teleconverter. Posted 7 years ago
I can totally relate to the remarks about distance. I'm still on 1:1 and really need the 105mm, preferably it was more, to capture subjects. That said, with 47MP I don't always need 1:1, and can keep a bit more distance and crop it back in.
I'm not using tele on macro but do use one on the 80-400mm and frankly am not happy about it. It darkens the view finder and image quality is indeed a problem. Posted 7 years ago
Still so many beginner mistakes, but you have to start somewhere. Posted 7 years ago
