Jupiter-9!

.


This lens is very, very similar to my M 85 f/2 - maybe cooler colors, and definitely
softer wid open. But nice 'creative' bokeh, and stopped down to 5.6 - 11, super
duper sharp. 2.8 to 4.0 still shows some softness, but a lot of detail. A very
pleasing lens.

The two below are wide open:

1)

2)



The one below is at f/4:

3)



The rest are f/2.8 to f/5.6, I forget what's what:

4)

5)

6)


Cropped:
7)

8)

9)

10)

11)

12)

This is an M 42 lens, correct? Were these shot with your K20? or K100? Just curious how "green button" metering works with the M 42 lenses. By the way, great shots !! I especially like #s 5,9,10 & 12

Yes, it's m42, and I used my K20D.

The green button works pretty well, but with the J-9 it tends to overexpose about
25% of the time. I tend to set the first shot with the green button, and then
tweak shutter speed for the rest of the shots in the same environment. When
I change lighting situations, I use the green button again to reset.

I just wish Pentax could fix the green button metering on the K10D. My K110D does VERY well with M lenses, but my K10 is off except at F4.... Anything F 5.6 and above over exposes, and thing below F 4 underexposes.... here is a little test i did with my K110D and K10D, same lens, same settings https://www.pentaxforums.com/forums/229239-post23.html

Great collection J! I was wondering when you were going to post more photos from the Jupiter-9. I particularly like #9 and #12.

I have been taking quite a few photos with mine and will post a few if I get a chance.

Green button? I never use the green button with the J-9. Since it has a pre-set (manual) diaphragm, the easiest exposure is to use AV mode.

1) Focus wide open

2) Stop the lens down

3) Take the picture!

Unfortunately, the J-9 suffers from the same exposure issues as all non-A lenses when used on the K10D (can't say regarding the K20D). Wide open it will underexpose up to 4 stops. Exposure is fairly accurate at f/5.6 and f/8. At f/11 and f/16 the tendency is about 1 stop overexposure.

I generally find it best to chimp the exposure and examine the histogram to determine an appropriate exposure compensation (again this is easiest in AV mode).

Steve

Thanks Steve, I have been thinking about trying some M42's on my K10D, might have to try a few !! My pop has 2 Spotmatics, one with the 55 MM F 1.8, the other with the 50 MM F1.4.. all I need to do is get an adapter and give em a whirl

Edit: I just ordered an adapter from the Pentax web store, hopefully will have it by next weekend !!

Yup, that's the way. In fact, I prefer the manual aperture as it's continuous and you can see how the DoF varies. Very useful!

Jupiter 9 85/2 is very nice indeed. Here's a few more pics, first one at f/2, the second and third at f/2.8 i think.

Yep, this is definitely one of my favorite lenses when my subjects give me some time to shoot. Like stevebrot said it's inexpensive, and also well built.

And it's beautiful!



And it comes in an unsealed Cyrillic-covered box stuffed with crumpled up
Russian newspapers! And only takes 30 days to get to you!

(its worth it.)
