How To: Convert SDM to ScrewDrive + Video

Thanks to all for putting this instruction together. I used my K-5 to convert a 300mm F 4.0 * from SDM to screw drive this afternoon. The SDM failed on me right in the middle of an airshow. Fortunately, I have always preferred manual focusing so the overall effect on my images was minimal. The lens is working great now on all of my camera bodies.

Henrico I am so sorry to hear that your K-01 continues to have the shutter issue. Mine is working fine now. I have taken it out several times since my last post and it continues to work as it is supposed to.

K-01 shutter stuck

Hi all,

My K-01 (bumblebee) started having this issue a few months ago. I would turn it on and the shutter would not open. Like many of you, if I would turn it off and then back on again it would start working again. The issue got more and more frequent until one day last week it just stayed stuck. No matter how many times I turned it off and back on, nothing. I tried all of the suggestions in this thread and was starting to lose hope when I decided to try something different. I removed the lens and manually moved the shutter with a precision screwdriver to make sure that it would indeed move. Once I had confirmed that there wasn't something physically holding it closed, set the camera on my desk and turned it on without a lens attached. The first time the first focal plane shutter moved, but the second focal plane didn't move. The second time, the second focal plane moved as well as the first and the sensor could be seen. I continued to turn the camera on and off until both focal planes consistently opened and stayed open (5 or 6 times). Now the camera is working as before. I am currently recharging the battery and will be taking it out for test shoot this afternoon. I'll report back with my progress in a few days.

It appears that if I edit any image and submit it, it will start to load and then I get the error that the upload failed. If I take a straight from the camera JPG of the same image, it uploads fine. I have gone through every setting in Corel Paint Shop Pro 2020 and can't see anywhere that the exif information is being altered. Very frustrating, you can't even crop without it preventing the site to upload.

John,

Awesome shots at such a high ISO. I am curious though, how did you tame the noise so well? Most of my shots at even 1600 ISO have lots of noise artifacts. I am shooting in .PEF raw format and have the high ISO noise reduction turned off.

Regards,

Ray

Pentax K5 - faster shutterspeeds than the sync speed of 1/180 for dog portraits

Tuutje, it is very possible that the person who took those images with flash at 1/640 shutter speed was using a camera with a leaf-shutter lens installed. A medium format camera with a leaf-shutter will sync at any shutter speed the lens is set for.

Just my 2 cents worth.

I recently acquired an old Honeywell Pentax Bellows Unit off flea-bay for under $15.00 and wanted to give it a test so I put a K-adapter on it and mounted my SMC Takumar 50mm f1.4 M42 lens on the front and headed to the backyard with my K5iis. Exposure data: Manual exposure at 1/160th, f11 (F 22 actual), Bellows extended to 1.6:1 mark, Sunpak 522 on manual set to 1/16th power. I handheld the camera and moved the camera closer and further away to focus (a bit tricky since the viewfinder was so dark, but live view helps). Razor thin depth-of-field even at this f-stop.

Great job by all of the artists. I must agree that this is one of the more difficult contests to pick a favorite. I must say that the depth-of-field in some of these really does make me feel like some "stacking" must have been applied. I can never get that kind of front to back sharpness in my non-stacked MACRO work.

Corel itself posted a similar offer a few months ago. It popped-up when you exited Paintshop Pro Photo X8. I clicked the link, it took me to the Cleverbridge site where I downloaded X-9, and three other softwares including Facefilter portrait re-touching software. I paid $14.99 back then also. Everything was legit.

This appears to be a M42 screw-mount Pentax Auto Bellows ll that has a M42 conversion ring mounted to a small Pentax extension tube so that it will accommodate the K-mount bodies. The lens appears to be a M42 screw-mount, fixed-focus, 100mm bellows lens.

Welcome to the club, mine is always with me in my car. I couple it with Pentax F 28-80 and a Pentax F 70-210 and love the results. I have also ventured to use it with a SMC 300 F4 and a Tokina 75-300 on occasion. My most used combo is with the Pentax F 50mm f1.7 though.

SMC DA* 300mm f4 focusing question
Posted By sawtooth235

Yeah,

I have been searching for a lens to produce great quality images at 300mm or more and have gone through a SMC-F 100mm-300mm, a SMC K-series 300mm f4, a Tokina 75mm-300mm, and the DA 55mm-300mm in my search. Looking forward to using this DA* 300mm. Some produce decent results and others just couldn't quite get sharp enough at the long end. Now that I have this I will probably be selling off the majority of these others.

Thanks everyone,

I have a DA 55mm-300mm that has quick shift on it but it still stops at both ends of the scale so I wanted to ask the authority, Pentax Forum Members.

I haven't had a chance to actual take it out for a test shooting yet and was just testing it prior to going out with it tomorrow and noticed this.

Looking forward to the results.

Thanks again,

Ray

SMC DA* 300mm f4 focusing question
Posted By sawtooth235

Hello all,

I recently purchased a copy of the DA* 300mm F4. When I mounted it to the camera I immediately noticed that the focus ring rotates freely all the way around in both directions. There is a difference in feel when you are in the range of where the scale shows through the window, but it doesn't stop at either end of the scale. Is this the way it works or is my copy faulty?

Thanks,

Ray

Pentax M f/4 100 mm Macro lens

As Just1MoreDave responded, you must go into the custom settings menu and allow the use of the aperture ring first to have the camera stop down the lens. If this isn't done then no lens with an aperture ring will work at anything but wide-open. Secondly, you can use the AV mode if you press the green button prior to depressing the shutter release. The lens will stop down and the built-in light meter will measure the light going through the stopped down lens. Personally, I have found that when using macro lenses I get my best results when using flash to supplement the light. It does 2 things, first it adds more light, and second it stops camera shake or subject movement from spoiling my images. If you decide to use flash, then set your camera to M (manual) and set the shutter speed to 1/160th of a second and your aperture at F11 (going to F16 or F22 can cause diffraction and soften your images) and shoot away. I have the same set-up and have achieved very good results.

My 2 cents worth,

Ray
