The close-up filters are a good field expedient for the Q's regardless of the lens. I've adopted the 40.5mm - 49mm step-up ring and a already available set of 49mm filters is a universal solution for my Q7 from 08 to 02 lenses with very good results.

Especially so since two filters plus the SU adapter take up less than half the room in the compact bag or pocket than a second lens. I find that with the Q lenses only two filters cover my needs -- the +2 and +10.

Some days the +1 and +2 would be all that's needed in the back yard/garden. How often does anyone attempt true macro (1:1) in the field anyway?

My best "garden macro" accessory is a DIY magnifier loupe for the LCD screen!

Indeed, and here's my solution to this "problem":



A good old-fashioned slide viewer (5cm x 5cm FOV - can still be bought new here and there) converted to a Q-system LCD viewer

Nice adaptation.

My favorite in the field is a folding Hoodman shade with an adapted magnifying loupe. Collapsed it's pocket-sized.

Hole is to remind me to shut off the camera when closed.

Jumping spider hairdo

This was the first time that this tiny on-camera flash was genuinely useful for me.

Shot with 25.4mm fixed focus C-mount lens and 10mm spacer. I felt as if the flash was mostly useless, but when the camera is close (my lens "hood" was probably 4" or so away from the subject) it actually delivers some useful light, and the lens barrel/hood was small enough it didn't block the light.

Morning dew + insect with my new achromatic close up lens

Hi,
just before my summer holiday I made a 40,5mm fitting for an achromatic close up lens intended for a 1980s Sigma 80-200 zoom.

Here is one of the images I made with it. It is a 100% crop but compressed a bit more for small file size.

Thank you Stone G, this was with Q7, ISO200, 1/13 sec, flash on, I think the aperture was either f/5.6 or f/8.

This is the picture of the setup.

I've got the exact same setup, here's one I shot a couple of days ago:
Nice!
You also used Wollensak Cine-Raptar 25.4mm f2.8? That's cool, I've never seen anybody other than me using that.

I looked again, its actually a Revere but it has the exact same "bright-hazy-dull" "winter-summer" engravings.
Interesting, maybe they were both made by Wollensak.

Mine is actually Wollensak-Keystone. I bought the lens with a Keystone movie camera at a local shop, apparently they were sold together by Keystone as a kit back then.

This was taken with a FD mount Vivitar Series 1 90mm 1:2.5 VMC macro lens and a third party FD-Q adaptor.

Hunter and prey by k kwb, on Flickr

This specific shot was taken with f/8 and a cheap third-party hood on a tripod.

This is my first "real" macro lens though it only goes to 1:2. Coming from a fixed focus Wollensak 25.4mm C-mount lens I talked about previously in this thread, here are my observations.

Pros:
  1. It's nice to be able to adjust focus, and this lens has a nice smooth focus action. With my fixed focus Wollensak I need to move the camera closer or farther.
  2. Optically excellent for Q7. Very sharp. Minimal purple fringing.
  3. 90mm means that you're at a comfortable distance so the subject is not scared away.
Cons:
  1. Heavy. It's heavier than my 250mm telescope (see this post in Adapted lens thread about the telescope), and probably an order of magnitude heavier than my Wollensak.
  2. Hard to hand-hold on Q7 for me. I think it would be easier if the barrel is a bit longer so my left hand goes a bit farther away to stably hold it (my telescope is somewhat easier than this one). A small tripod helps.
  3. The lens blocks the built-in flash. My Wollensak doesn't.
All in all this is an excellent lens for MaQro. (But if you can get close to the subject and if you're OK with fixed focus, Wollensak is not bad either, especially for the price.)

Another jumping spider shot with Wollensak/Q7

I was quite sure that I posted this, but it doesn't seem to be the case, so here it is.


Peekaboo! by k kwb, on Flickr

This was shot with Q7, Wollensak Cine Raptar 1" (f/2.5) lens, 15mm spacer (actually 3 pieces of 5mm stacked together) and pop-up flash.

Tulips with Q7+06@45mm+10mm tube

Four tulip macro shots - Q7 with 06@45mm on a 10mm tube. Hand held using a LED ring light.









Magnification with this setup: better than 1:1 on a FF - an object 30mm wide fills the frame. As a bonus you have a very comfortable working distance of about 15 centimeters.

Phil, nice colors and details! 06 lens and a spacer seems to be a very good combination. Can you adjust the aperture with your setup? What kind of extension tube do you have?
