Re: Having Fun With the Opteka f/4 1:1 Wide Angle Macro Lens

Great results! Looks like a fun lens. I'll have to look into this lens at some point myself. Right now I'm cobbling together a WA relay rig to experiment with. The Opteka would likely be easier to use, but I already have, or have on the way,the ingredients for the relay, so I want to give it a go fi...

Re: Suggestions for CCTV lenses for w/a macro relay set-up?

I went ahead and ordered another bit for my eventual wide-angle macro relay lens today. I found a great deal on a Fujinon 2.7mm f1.8 C-mount fisheye lens. The version I got is the fixed aperture 1.8 one, rather than the manual aperture version, which is more expensive. I'd come across references to ...

Suggestions for CCTV lenses for w/a macro relay set-up?

Hi all; I assume that an M12 CCTV lens rated for 12 megapixels will give better results than one for 5 megapixels when used as the front element of a w/a or fisheye macro relay lens? It would be good to hear confirmation of this from someone who has found the answer themselves. I realize that a setu...

Re: Reversed wide angle vs. telephoto for w/a macro relay

Hello I'm playing with a similar setup now yes the extra spacing is the Tamron extension; and autofocus and iris should be working; this is a mayor advantage against the other relay system with inverted wide. The system is as Rik wrote, the Tamron picks the aerial image of the 2.1mm lens in front. ...

Re: Reversed wide angle vs. telephoto for w/a macro relay

Gil Wizen http://gilwizen.com/wide-angle-macro-1/ , after using reversed w/a lenses in his relay system, found another solution which was easier to use. I'll quote a bit from his website: In the previous post I mentioned that one can achieve a satisfying wide-angle macro effect using a relay lens sy...

Re: Reversed wide angle vs. telephoto for w/a macro relay

Good catch! I'm thinking that the extra extension is the Tamron's focus travel. In the set-up image, the lens is at its minimum length, focused at infinity. In use, it is focused closer. Assuming that the extension tubes between the camera and the Tamron are automatic, then he still has aperture con...

Reversed wide angle vs. telephoto for w/a macro relay

Hi all; All of the fish-eye/wideangle macro relay set-ups I've come across online (including here on the Forum) have used reversed wide angle lenses as part of the assembly. This evening, in looking at what people have done with Raynox achromats on Tamron 90mm lenses (having just bought a used 72B e...

They're all excellent, but 1 and 3 are my favourites. Really great colour, clarity, and form. Nicely lit.

Re: Flash on the hotshoe

I have an "invention" in mind where one or more off-camera flash units are mounted on ones' head. They are adjusted to be in good position when the camera is brought up to look thru the viewfinder. Now this would save weight on the camera, certainly, but it would be better if no one sees you wearin...

Re: Flash on the hotshoe

There are several folks who mount a single flash on the hot shoe, and then use a diffuser that directs the light forward and downward. There are definite advantages to shooting 'flash forward', but the armatures for doing that also add to the weight and awkwardness of a rig. I just took delivery of...
