A Couple of Flies and a couple of Bees.

All shot with a 180mm lens and a 1.4X TC... Personally I am not a fan of the 2X TC's I had one but finally sold it, the 1.4X I think offers acceptable quality while at the same time allows for infinity focus. That is probably the only advantage if offers over tubes. It is kinda nice because my Macro lens can double as a medium length telephoto lens.
If you enlarge the bee pics you can see the compound eye which is a big marker for me.

How does the extender affect DOF. Are you further/deeper DOF??

I don't think that you can get away from Higher Magnification = Reduced DOF... I just put that setup on about 37mm of tubes and I am getting 2X magnification with a 10" working distance... I can also focus up to close to 20 feet away, of course I am no longer shooting macro when focused so far out... I will check it out tomorrow and see how it works for me with the iris closed at f/11 and see if I have the same flare problems... That Macro lens has a huge hood maybe it will be better on the tubes than the reversed lenses were.How does the extender affect DOF. Are you further/deeper DOF??

I am not quite sure how the math works out, that lens has about an 11 inch MWD which does not change when the TC is attached so at MWD you are getting 1.4 : 1, So of course you can focus a little further away, I would expect something close to between 15 and 16 inches and still be at 1:1... Honestly I never was so concerned about 1:1 until I learned about the rules of this forum, I guess you could say that I was a Macro hobbyist rather than a True Macro hobbyist...#3 + the bees for me.

At this point, I'm more interested in MWD. Yesterday, I had 36mm ext + the 105 @ 1:1 with the Raynox to try to get better resolution on aphids. I was so close I kept bumping into parts of the plant while trying to hand hold the DIY soft box. I went 0fer.I am not quite sure how the math works out, that lens has about an 11 inch MWD which does not change when the TC is attached so at MWD you are getting 1.4 : 1, So of course you can focus a little further away, I would expect something close to between 15 and 16 inches and still be at 1:1...

Yes, I can understand when shooting stacked lenses with my 100/50 setup the only focusing distance at 3X was something like 1.5 inches and the diffuser was often an issue.. The 180 on tubes does better than the 100mm did, I don't know why but it seems to retain ability to focus at much greater distances than the 100mm did and like I said earlier a very generous minimum working distance.At this point, I'm more interested in MWD.

I've never owned one. I've heard that the 1.4x is very good, but the 1.7x & 2x-- not so much.Yes, I can understand when shooting stacked lenses with my 100/50 setup the only focusing distance at 3X was something like 1.5 inches and the diffuser was often an issue..

That does seem to be the feed back, I did finally let my 2X go.. I am not so sure that I was not partially to blame for some of the results, but I can also say that I don't really miss it, the 1.4 seems to be more than adequate for what I use the extender for in Macro and with my long lens which is a f/3.5 I lost auto focus with the 2X so it was not good for birding either.I've never owned one.

I went ahead and put the full set of tubes on and am getting 2.5 : 1 magnification with a 8.5" working distance... Kinda stoked about that but it is a beast and somewhat heavy... Looks like I may have to start working out again... LOL.. It will focus out to about 8 feet with the full set of tubes, definitely offers me more shooting opportunities than do the reversed lenses... We will see what kind of quality it produces.

Are you shooting handheld with that thing?

Yes, but that is not the rig that I normally use, in fact I had pretty much stopped using my 180mm lens until my 100mm broke... If it gets to heavy I have a trick that I actually picked up from reading Lord V's post at the beginning of this section, haha I shamelessly promote that blog because it is some of the best information you will find on shooting Macro, but back to my point, if it gets hard to manage I can carry a painter's extension pole kinda like a walking cane and use it to balance and steady the camera by locking the hand I use to support the lens with around the rod... It does not give the same support that a tripod or monopod does but it allows much more freedom in adjusting the camera height in relation to the ground and adjusting the angle of the shot because you simply slide your hand up and down the pole.Are you shooting handheld with that thing?
