I was suprised how tough that glass really was! There was a center section that had part of the optics that came out also (didn't mean to do that). It will still stop down the lens (up to a point). I found out that you don't focus with the ring - just move the camera around to focus. It worked, but it does seem limited as far as focus and DOF. Think the Phoenix lens would be what I should get, rather than extension tubes (though I now have a useful extension tube instead of a poor teleconverter). It's been an interesting day.

A couple of examples taken with the 50mm lens:



Baby Grapes - these will be a bunch of grapes in a few months:

I did the follwing test:

First two shots with SMC-M 100 mm f4 Macro lens at f 8 and f 22. Then two shots with SMC-FA 50 mm f1.4 with a Vivitar Auto extension tube 20 mm (then the FA lens behaves as a fully manual lens, automatic stop down but no AF and no auto metering). The lens set to f8 and then to f 22. Welcome to judge yourself.

HARRIET !!!!!

these are great!!! looks like all you need to do is stop down the lens for more DOF as shown in kjell's post.. glad i was able to give you a cheap way of doing macros.. isn't it fun???
kjell, great post. i was going to do the same.. you beat me to it..


mtngal, the phoenix is suppose to have superb optics but is built like a POS.. you'll have a lot of fun with it. you might take a look on ebay, i see them there all the time.. you also might look for some of the older better macro lenses that are offered there..

I'll have to experiment more - I didn't have anything close to your DOF, even with the 50mm lens set to f22. Your pictures certainly show little difference between the lenses - maybe I've messed up the mechanism that stops down the lens when you press the shutter (it did stop down the lens to meter, though).

I almost didn't include the dandilion - I would have liked it better if I had gotten it sharper. I was impressed with the bunch of grapes - they are only about an inch long at this point, and I find it hard to tell that they are grapes at this point(the grapevine is on my front porch -nice sweetgrapes if the birds don't get them first).

Thanks again for all the encouragement (and now to spend the rest of my lunch hour playing with my new extension tube and seeing if I can get more DOF).

i'm sure glad you posted the dandelion. actually it's one of my favorite TYPE of shot i like to shoot in raw. that's because you can add a lot of shadow to the image in order to really bring the highlights out..
