Topic: Redrock Macro adapter on SurplusShed

UPDATE 1 My Surplus Shed order arrived a couple of days ago. This thing is big and heavy, glass and metal, about the size of of a hockey puck. Hanging this much weight off the front of some lenses (as is my intended use) may be problematic. I can imagine some lightweight, modern, plasticky zooms pro...

One advantage of those little alternatives is the ease of lighting the subjects. The fisheye attachments I have seen are huge and make lighting challenging. Excellent point I had not considered. I also wonder about the minimum focusing distances. The smaller lenses seem to be able to get much close...

Have you checked the Laowa 15mm F4 (https://www.venuslens.net/product/laowa-15mm-f/). It is for interchangeable lens cameras, but it could be something of your interest. This certainly looks like an interesting lens, but it's outside what I can afford at this point. The results from DIY rigs assemb...

I've ordered one. I'm hoping it might be a cheaper Raynox susbstitute I can use on my 55-300 zoom for those occasions I don't want to carry an actual macro lens with me. I'm very curious to see what everyone here does with this, too. It's good to have multiple ways to do the same or similar things a...

Fisheye macro using P&S adapters?

Hi all; A number of photographers who have done fisheye macro work, like John Hallmen https://www.flickr.com/photos/johnhallmen/29958568915/#comment72157674444663445 and Gil Wizen http://gilwizen.com/wide-angle-macro-1/ have built macro rigs around small "board lens" optics, cell phone fisheye adapt...

I guess I don't have a specific magnification in mind, I mostly just mess around with whatever I happen to have. I should really sit down and test & try the various combinations of reversal, extension and stacking with the lenses I've got to find out what works best for what. Just doing that would k...

If it's a wide-angle lens, such as a retrofocus designed 28mm for use on full frame, then the designer had to make compromises for that. Something like the better of the Nikon 28mm lenses (the 8 element one) isn't bad at all reversed. There are no 28mm macro lenses afaik. I was thinking of the Pent...

Reversed wide macro lens performance

Would a reversed macro lens (either on the camera or stacked on a longer focal length lens) give better results than a reversed non-macro lens of the same focal length? I'm thinking of focal lengths shorter than 50mm and magnifications greater than 1:1. I've seen Thomas Shahan's results from reverse...

I wonder how they ever catch such actively flying prey, since they seem so sedentary. But on that point, I think they would be a great live subject for focus stacking. They have interesting textures that would show up well with that method. I've not really tried focus stacking. I've done a bit of h...

Are you're referring to the pattern of dark dots? Those look to me like a distorted version of the hexagonal pattern that we often see in butterfly eyes. From reading various articles, my understanding is that the anatomy of these eyes allows the dark-colored photoreceptors of each ommatidium to se...

A successful ambush

Seeing other posts on bugs munching bugs, I realised I have I can add to the gallery of photos of the Diners Club. Here are some shots I took of an ambush bug with an unfortunate fly it had captured. http://www.photomacrography.net/forum/userpix/7182_Ambush_1_2.jpg http://www.photomacrography.net/fo...

Replies: 7

Lefkowitz recommends using normal cine lenses and notes that "zooms and particularly wide angles, will not be as sharp. About 15mm focal length is right for Super-8 or old 8mm film; 25mm is standard for 16mm film." My most used cine lens is a Kinotel 1 1/2" (about 38mm, so a telephoto, as the name s...

Thanks for your replies. I've got Lefkowitz; he doesn't recommend cine zoom lenses, but I'm still curious. The fact that nobody seems to have done anything with them that I could find might be a clue too. I haven't tried stacking my reversed cine primes, I've just used extension, so that is certainl...
