ChrBra, forgot about that one . I saw it but didn't have time to react and didn't come back to it. Good you "bumped".

I think sharpness suffers a bit using that lens so close, but there's still plenty of detail and texture to see for a pass.

Thanks Pieter, no problemo. I might re-shot this assignment when my "new" tripod arrives, this was more to see what kind of magnification the reversed 28 mm would give.

My first use of the A700 for Macro. (I usually use my A100)
MC Rokkor 50 1.4 with stacked Kenko extension tubes (12mm+20mm+36mm)
ISO 200 f11 @1 sec. w/ Opteka ring light

To see is to enjoy. To see beyond is to rejoice.

@Basil: Even I could thread that needle! Given that you stacked all three tubes in the set, I'm sure you have achieved the "greater than 1:1" objective (and receive a pass on the assignment), but I am curious about the actual dimensions in the image. An off-center (or diagonal)composition would have given the image more impact and moved a step beyond the technical requirements for the assignment.

@snajper: You have earned a pass on the assignemnt. Some information on the actual size of the image would still be of interest. I do note some vignetting which is common on reverse setups when the outer lens is not fully open or when the focal length of the inner lens is too small.

Cheers (and congratulations to both)... Brian

Brian,

I did a diagonal view using a Mamiya Sekor 135 2.8 and a bellows. With that set-up the image worked. But when I tried it with the 50 1.4, there was too much of the image out of focus to my liking. Even at f11, there is a very narrow field of focus. (Note how quickly the thread
gets blurry). Stopping down further made lighting an issue at such a close working distance. It just looked better this way (at least to me).

Okay, another try! 50mm f/1.7 fully open on camera body, with 18-70mm (@ 70mm) kit lens (borrowed from a neighbour) reversed, and aperture held open using a piece of rolled paper. Not attached using a ring, but placed together, A4 paper wrapped around both to keep together, and stuck with tape, and a pringles tube cut down and slid over the top to keep things secure. My watch, side lit, taken using a tripod, ISO 100.


Hope this is acceptable, it was certainly fun learning.

@Berean: Well done, Ian! Sounds a lot less expensive (and more fun) than the closeup lenses and extension tubes you were considering . Consider yourself passed. Cheers... Brian

Is it allowed to use an older photo if itīs made with the mentioned techniques? Praktika 50mm f:1.7 reversed on my Beercan.
If so I have a very cool B&W beetle and a 40 million year old spider captured in a piece of amber

@Heyckendorff: Sorry, Werner . The assignment rules (on the previous page) say no "mining" of old photos. Of course we'd all be interested to see the shot, but it would not qualify for as passing entry for the assignment.

Cheers... Brian

Well there goes my predicted relaxing afternoon on the couch

Then I have to start a fresh on the amber spider.

Berean,

Great shot and a great low-cost way to get it, especially using a couple of non-exotic lenses. That's the fun of this type of photography...you can get really good results for not a lot of $$$.

It's like making your own light modifiers out of cardboard or bubble wrap. While some may be intimidated to show up in public with such "tacky" equipment, you can have tons of fun in the privacy of your own home/yard.
To see is to enjoy. To see beyond is to rejoice.

Thanks, Basil! No expense whatsoever!

I'm relatively new to this hobby, and I'm just beginning to realise (since being on Dyxum) that one doesn't need a great deal of dosh for good results!
