Well it is Very Interesting  As a specialty lens, it is absolutely USELESS at anything but what it was designed to do. WARNING: it IS a specialty lens that will do NOTHING but 1:1 or better, and thats anywhere between 1:1 to 1:5 oh woweeeee, where does one start? LIGHT LOSS: if you do a sum/math/arithmetic that I can't be bothered explaining, to get "Effective f/stop" over magnification ..... just trust me .... 5X / f16 = Effective f92  hot damn thats a LOT of light loss. DOF: ? ..... WHAT DOF?! ... 1:1 f/16 > 2.24mm ... 1:5 f16 > 0.269mm clearly shows NO DOF! v  Working distance: 100mm 1:1 down to 41mm at 1:5 [100mm away is all you can go, thats it, no more, the lens is a specialty lens, and the maximum focus distance is 100mm][4 inches] Tripod is a MUST, Focussing Rail would be bloody nice!!!! Remote Trigger is a MUST, you wont hand hold it, and deffo will not press the shutter button! without blur, Lighting. I'm actually as happy as a pig in cheese with it, after trying it out even with the LIMITATIONs it has, the results could be stunning, if one works at technique .... PATIENTS ...... maybe buy a *******ing focus rail, or make one, get into Focus Stacking [i think i already have the program?][focus rails are even computer driven these days, WOW][more batteries]It's not a lens for the feint hearted, think wisely Glasshoppas!!! it is a rewarding art of photography, but a BIG expensive mistake if you can't do the technical associated with it, or want a 'versatile' lens. Smell me later |
