2nd try with Ext Tubes - no stacking

silvio000

So yesterday i spent some more time chasing bees and flys.
Still getting used to the ExtTubes.

Do you use the ExtTubes with autofocus or manual?









Thanks for watching,

All depends on the set of tubes you have, if they are a "no contacts" style of tube, everything must be done manually. Tubes with contacts tend to be more pricey but according to the manufacturer you will retain AF and Aperture control with them.

Hope this helps a bit.

Not bad at all- first subject is a fly Stomorhina lunata - other bug is a hoverfly. Shots suffering a bit from limited DOF and strong sunlight. It gets easier with flash. I assume your ext tubes are auto tubes (ie have contacts) but whilst this allows full aperture control which you do need, when shooting around 1:1 magnification or higher (these pics look more like 2:1 or more) I always use manual focus.

Thanks JD and Brian.

My tubes are automatic, yes.

Yesterday at night, i tried to use the Tubes with autofocus and found it even more difficult to use. Will keep using manual. Now i need to improve the stacking technique. :-)

Brian, maybe the 2:1 look has something to do with the D7100 1.3x crop mode.
