Viltrox DG-C Macro Extension Tubes
Rather than buy a macro lens I've ordered the above extension tube set for my Canon. I'm keeping my Nikon D3200 with the 300 lens for wildlife but its unsuitable for dragon flies and macro. My Canon EOS has a 35-76 on board at the moment so I'm going to give it a try with the extensions.
Its a 3 way set and i'm just wondering how much closer they get you. Some are saying all three tubes in tandem get you to 2 inch and focus becomes really difficult.
I'm looking to get about 6 inch so maybe 2 together will suffice?

Remember that the closer you get to the subject, the shallower the dof. You're looking at only a couple of millimeters in focus at the closest range, so you may also want to investigate stacking. Some cameras have it built-in , or it can be done fairly simply in processing software afterwards.

The best answer to that is to experiment with different combinations of the three pieces and fins out just what they offer...

Here is a good and informative article which is well worth the read, points disadvantages as well as advantages. I have not tried your lens but it may take IQ performance hit,

You can certainly use a combination of tubes together.
There will be a perfformace los as Phil suggests, with a zoom. That sid, I have done so myself on occasion and while that's a general guide that 'loss' may be small and not worth worrying about.
What you will find is that small change to the focal lenght will affect focus and magnification and you may well need to get very close to your subject. so getting in the way of the light or scaing an insect away are the dangers.
You will find a setting or combination that works well enough, it just needs a little experimentation.

I've dabbled with extension tubes. They're a terrific way of dabbling in macro without the expense of a dedicated macro lens. Although I haven't tried photographing insects, I can't imagine getting close enough to one without scaring it off, and as Dark Lord says, you may block your light. Here are a couple of examples of the magnification you can expect but I'm afraid I didn't make note of the amount of extension used for each.

I do recall messing around with them and looking at some printed text, and the lens was practically touching the paper, so short is your lens-to-subject distance, if going for a large degree of magnification.
I've been short on detail but I hope it helped, at least a little.

Thats pretty good imho, was this tripod ?
Can you add the exif so we can see the settings, the very centre looks pretty sharp so either a smaller aperture or stacking is needed.
Ive had good success with normal lenses with an extension tube as well as a macro plus a tube

Quote:shake becomes a serious issue.
Tripod is a must. Also, always use either the self-timer or a remote release - cable or wireless. That will ensure you eliminate any unwanted camera movement at the moment the image is taken.

Hand held. The 20mm is much the same as the 36mm so I've put the 12mm on.
The 12mm gives the zoom back and you can pretty much choose your distance anywhere from 12 inches down to 2 inches. It also allows more DOF and autofocus works pretty well although manual is better.
I took this one just now hand held.
