I absolutely love this old lens. It's considered one of the best lens ever made by Mike Johnston at Sunday Morning Photographer. I managed to score one off ebay for $50. It works great in Av mode.

Here are two pics I took with it...

yeah I used to have one on my 1st camera (K1000), I loved how smooth the focus ring felt - a joy to use. I've been trying to buy one for a month or so now - curse you astro, now everyone will be competing with me on ebay:)

I actually have two :)
The Super-Multi-Coated Takumar, and the SMC Takumar, and I have the Pentax-M version too.
They're all pretty much the same.

Just took this macro of this beetle with the same lens + extender tubes :)
and my ghetto bounce flash mod.

Astro nice shot of the beetle

Thanks. I also compared the 50mm F/1.4 lens with the 50mm F/4 macro. I find the 50mm F/1.4 FAR FAR sharper than the 50mm F/4 macro. Maybe my macro lens has a defect.

Anyways, here's another shot with the same SMC Takumar 50mm F/1.4 lens.

I like the macros but I am curious what F-stop you are using. The DOF seems to fall short for your beetle. Considering the amount of light your lens lets it, I would think it optimal to choose to increase DOF by decreasing your aperture.

Yeah it's hard to get a nice DoF when I'm so close up. I'm at minimum focus with full extender tubes on.

I'm using F/11 to shoot. F/16 is the next step down, the minimum aperture for the lens, and would probably cause quite a bit of diffraction. So I use F/11 to maximize image quality.

Well I got my hands on a SMC Pentax-A 50mm F1.4 ... very nice, fast, sharp, and cheap ! ... off to take photos now !

Sorry, I'm still a photo n00b. But what exactly do the tubes do?

and when using a teleconvertor x2, my lens doubles but what about the aperture. I've read from places that it drops by two and from other places that it doubles or something?

Hi cptofgondor,
Notice that when you focus a lens to a closer focus, you'll see that the lens will extend out of the tube. Basically lenses are able to focus when they are farther away from the sensor. Thus, extension tubes are useful for allowing your lens to focus closer as it places the lens dramatically farther away from the camera. Macro lens generally work the same way, allowing you to extend the lens extremely far out from the camera - basically built in extension tubes.
Extension tubes' only job is to extend the lens from the camera, meaning there is no optical elements that can degrade the lens, unlike teleconverters.
