I went and bought the Sigma lens, it arrived this afternoon. It looks to be exactly what I was looking for, however I will have to wait until my current roll of film is developed to see just what is what. The light intensity from my plant lights keeps the exposure time quite short even with ASA 800 film.

I am going to need Program AE, which means looking for a replacement lens, a true macro lens. Photography is not a never will be my hobby. This is all so I can record and share my plants.

I always manually focused, no problem. The Promaster lens first has no electrical contact so I can't use AE, and it although it is marked on the front 1:28, the barell
markings don't go lower than 1:4. I can't get close enough for detail and remain in focus

My macro lens is an Auto Promaster MC 1:2.8 50mm. Marked on the side of the lens is an indicator: Macro 1:10, 1:8, 1:5, 1:4. Would extension tubes still allow autofocus (this is not a killer issue)? Also, I always shoot in AE mode (I'm not much of a photographer), the lens doesn't have an electrical contact. How would aperture priority function?

This is beginning to run out of my budget, I am comfortable under $300.

The pollen structures are secondary to the rest of the flower structure and the plant itself, with my budget I can't have everything. Needless to say the photo is still better than anything I can get.

This photo was taken with a smart phone, the plant and flower fairly typical, but on the small range in size. The biggest flower in no deeper than 3/4".
I would like to get pictures of the same sort of quality as the smartphone.

I would buy the Tamron 72B if I could find one. A half hour of Google searching (my Google-fu is pretty good) and I haven't found anything.
I am not much of a photographer. I have to use the camera in the programmed AE mode (aperture priority).

This is the photograph of one of the smaller plants and flowers posted to FaceBook. I would say the flowers are maybe a bit under 1/2" across. The whole plant is not much more than 1 1/4" from flower to base.

The Tamron is in my budget.

I have seen close up pictures of small objects with great depth of field. A friend's smartphone can do it. Nothing I am photographing is more than 1" back to front.

The Program Plus is a 35mm film camera. The "wrong" macro lens is a Promaster MC 1:2.8 24mm it says Auto, but the fstop does not show up in the LCD display in the viewfinder. I don't know if it means anything but there are no electrical contacts on the back of the lens mount. There is a slot for what should be the autofocus mechanism to engage.

I don't know If this thread was already posted but I will try again.
Years ago I purchased new a Pentax Program Plus, and a bit later I bought a macro lens. Well the lens turned out to be useless for what I want to do: take close up pictures of small plants and flowers. Researching the subject on the net I found a recommendation (for cost) to use a short-barrel, fixed focus lens with a 1:1 magnification ratio. With these particular plants and flowers I want a good depth of focus. Since it doesn't seem that there are any Pentax lenses that match the specifications, I wonder what else I can use. Cost is very important, I'm retired.
Thank you.

My name is Bill Lubarsky and I'm a retired engineer. One of my main hobbies is growing succulent plants and I would like to take good close up pictures of the plants and flowers. I have an old Pentax Program Plus with the wrong macro lens.
