[QUOTE="Fortkentdad, post: 658432, member: 24285"] I suppose some would say that it is silly to think about adding a teleconverter aka TC to a lens designed as a walk about to save you the trouble of swapping lenses. And the lens I have claims to be a macro so why an extension tube? Well I have TC's and I have ET's and I even have a snap on the front of your lens Raynox 250 magnifier, and some time, so lets just see what happens. First off the T.C. - yes it worked, and worked OK. The TC used was the Kenko Pro 300 - 1.4. A shot of the single bullrush sticking out of my frozen solid goldfish pond. The EXIF should tell you which is which. [ATTACH=CONFIG]279956._xfImport[/ATTACH][ATTACH=CONFIG]279957._xfImport[/ATTACH] (first no TC, Second with 1.4) Also shot a few sparrows in a cedar bush. [ATTACH=CONFIG]279958._xfImport[/ATTACH][ATTACH=CONFIG]279959._xfImport[/ATTACH] TC and then ........... No TC Sure it costs a stop (1.4x) but gets you 40% closer. .... would I likely use it? Maybe - but probably not. but good to know it will work if you need to get a little bit closer..... (come on hum it with me ...) --------------- And as for E.T.'s and that RayNox Snap-on magnifier They both nullified the autofocus - but hey it is macro shooting should be done manual focus anyway eh? The Extension tubes (used the 12mm and 20mm - not stacked) were challenging as you had to get extremely close to the subject. [ATTACH=CONFIG]279960._xfImport[/ATTACH]+ The Raynox was easier to use as you didn't have to be just a couple of centimeters away from the subject (more like a decimeter or so - 3" for those in the the old system). Getting that close makes it tricky for lighting. BUT the Raynox doe create the dark circle - I suppose one could pretend it is intended as a magnifying glass effect. [ATTACH=CONFIG]279961._xfImport[/ATTACH] So they work ... But the lens does an pretty good job of extreme close up (and AF works) and unless you need that extra magnification I wouldn't bother. If you do, use a real macro lens. If you only have this one lens and have the E.T. or snap -on magnifying filters why not use them. Here is 'Super-Siggy' version of a macro shot unaided. [ATTACH=CONFIG]279965._xfImport[/ATTACH] I'm sure in the right hands these tools may return different results but for me, I don't see the advantage to the macro aids while the TC has some benefit but may not be worth the bother to get that extra 100mm in reach?
