Pentacon 135mm f2.8 15 Blade M42

Return To Homepage

I purchased this lens from a member of a forum I visit. It had a rattle inside – I had been advised of this problem prior to purchase. Listening closely, I determined the noise was coming from the front end of the lens. I removed the front lens itself. The next lens down towards the aperture was shifting approximately 1/32nd of an inch. I found a cross section diagram of the lens on the Internet and saw that I would have to take then lens completely apart to tighten it up.

HERESY NOTICE – HERESY AHEAD! PURISTS SHOULD AVERT THEIR EYES AND GO ELSEWHERE!

I dropped a small drop of super glue at the joint between the lens and the barrel. I then quickly turned the lens mount side up – forcing the lens to ‘fall’ into place. A couple of minutes later, I turned it back up and applied a couple more small drops of glue around the perimeter and let it dry.

Here is a quick shot I took of a lamp globe handheld to check it out. I think I have a user. The main reason I wanted this particular lens was the number of aperture blades. I hope it gives me a nice star burst pattern. If you have an uneven number of blades, the number of ‘rays’ from bright sources is doubled. So, there hopefully will be thirty rays. Also, this lens is marked Made In G.D.R.

I recently purchased an adapter to mate M42 lenses to my Olympus E-510. The seller gave me a set of directions referring to the E1 family with a couple of updates supposedly referring to the E-510. Needless to say, they didn’t work. I then found three other sets of instructions on the Internet in various forums. None of these worked, I am assuming the writers had never had an E-510 within fifty yards of themselves and had only reworked what others had written.

What follows is exactly what I found to work with the Dandelion chip and my E-510. They will include how I set the custom aperture and focal length.

These first steps have to be taken first every time a setting is to be changed -they put the camera/adapter into a programming mode -

Turn the camera on

Set the mode to A

Set the focus to MF mode

Press the FN button just below the wheel to the right of the mode dial.

Press and release the lens release button – a simple push and release – do not rotate the lens

Within one second of the above step press and hold the FN button for three seconds

Release the FN button

Press and release the lens release button – a simple push and release – do not rotate the lens

At this point the aperture value should change as the wheel to the right of the mode dial is rotated – if not – turn the camera off and start over. If it doesn’t work after several attempts you may have a different Dandelion chip version than I have.

Note – The above steps have set the camera and chip in to a programing state. The next value entered will access a particular portion of the chip. To set the aperture use f5.6; to set the focal length use f8.0 The focus and the aperture of the M42 manual lens have no bearing on doing the programing. Leave the lens wide open and set the camera to allow shutter trip without the focus LED being active (MF).

Note – After changing either the aperture or focal length turn the camera off. Don’t just start changing the other value – the chip will get a headache.

Below are the steps to be taken AFTER entering the program mode – one set for aperture and another set for focal length (which I am assuming from my experience and Internet comments sets the IS feature value)-
———————–
To adjust the aperture value in the chip

Using the wheel, adjust the aperture value to 5.6 *

Press the FN button and release

a)Turn the wheel to select the first digit of the f value you want – referring to the values below

b)Make sure the lens cap is off and point at a fairly bright light source

c)Press the shutter completely down and release allowing only one shutter action to be completed – wait for the image to be saved on the card before continuing.

Set the second digit and do steps a, b and c again.

Press and release the lens release button

Turn off the camera

=====
F4.0=0 | F4.5=1 | F5.0=2 | F5.6=3 | F6.3=4 | F7.1=5 | F8.0=6 | F9.0=7 | F10=8 | F11=9

IE to set an aperture of 4.5 the first aperture value is 6.3 the second aperture value is 7.1

Values that can be entered are f1.0 to f8.0
=====

The value you choose should now be displayed and still there after turning off the camera, removing and replacing the lens and adapter and turning the camera back on

————————

To set the focal length –

Use the value of 8.0 rather than 5.6 *

Using the same values from the line above set five digits rather than 2

Otherwise each step is the same as for aperture

IE to set a focal length of 135 the values entered would be –

4.0 | 4.0 | 4.5 | 5.6 | 7.1

Values that can be entered are from 00001mm to 65535mm

The popular consensus is – the closer the focal length entered matches the lenses value, the better the IS works – thus it appears to be useful with a zoom lens you would have to fiddle each time you change the zoom value. I only use primes with these adapters. The default is said to be 65535mm, so either turn off the IS or set the value correctly before trying any actual photography. I was having a heck of a time the first time out after mounting the adapter with its original f2.8 and 65000mm+ setting. I was getting very out of focus and fuzzy results when the aperture was stepped down to 4.0 or smaller.

Using a Sears 50/1.4 I set the aperture for 2.0. I’ve found this setting to be useful with the RAW format from an actual 1.4 to 2.8 lens setting. The lens FL I set to 50mm.

Olympus E-510 Received

Return to Homepage

The camera arrived three days ago, but until this morning, the focus confirm M42-4/3 adapter hadn’t arrived. Until today all I had done was hold a Minolta lens in front of the camera to verify everything as working.

I made a few quick test shots today, none worth posting, to get used to the live view feature. I believe this might turn out to be a fantastic camera. By locking the mirror up and using the live view, it is possible to see the focus, framing and aperture adjustments in real time on the screen. I don’t see myself using the live view handheld, but, on a tripod I think it will shine.

Today I put a test roll through the Argus FA and dropped the roll off to be processed. The main thing I am concerned with are the dried out light seals. Depending on the results, I may have a project ahead of me. I have the material to use from other projects in case they are needed.

Graflex Optar f/4.5 127mm Images

Return To Homepage

I had a chance today, just before the rain came, to take these images. The sky was 100% overcast and pretty gloomy. The lens assembly is mounted in an old M42 135mm lens body with no aperture capability. The camera is my new (to me) Pentax *istD. The images are in a page to the right >>>>>>>>>>

A Pleasant Sunday Morning

Return To Homepage

The Sun was out for a change and I have been waiting to try out some of the many old lenses. I grabbed the VPK meniscus and the 1A Autographic lenses and headed out to a local private garden. Every day there are new displays and the flowers are usually rotated from one place to another to vary groupings, as a bonus the building is painted a bright orange and they sell a whole line of home supply items. I pulled right into a spot up front and proceeded to snap away for about thirty minutes.

Then I went to a local Erie Canal Park and took a couple quick shots with the 1A Autographic lens to get a feel for it.

The meniscus shots are on the VPK Meniscus 002 page and the page named 1A Autographic has the others.

Kodak Bimat Lens Images Added

Return To Homepage

There is a new page in the right hand column with six images taken with a Kodak Bimat lens. The lens was attached to an M42 extender tube, then to the end of a bellows. The bellows was attached to my Canon XTi with a focus confirming adapter.

A Replacement For The Damaged Fujifilm S1

Return To Homepage

In a moment of extreme weakness, I bought a Fujifilm S2 on the Bay. It will complement my Canon XTi, and Pentax istD. Now I can use just about any lens made for 35MM format cameras by simply mounting a non-optical adapter to one of the three cameras.

I await its arrival to set up a shootout with my lenses; to be posted here. I have several M42, a couple Nikon and a dozen custom mounted pre-1939 uncoated lenses to try out. I am figuring at least three hours will be needed to finish it all. Perhaps three segments by aperture settings, to keep the lighting somewhat even, on a very clear day. 10:30AM to 1:30PM seems a goal.

Nearby my house is a small park that has a nice section where there are trees, shrubs, buildings, play ground equipment, etc to allow DOF to be apparent. The results will be posted here on separate pages. Maybe within a month I will get it completed.

M42 Lens On Nikon F Mount Modification – On Fujifilm S1 PRO

Return To Homepage

Adapter Information On This Blog

Long story short-

I have modified my Fujifilm S1 PRO to accept M42 lenses directly without need of an optical adapter.
I have destroyed the sensor on the Fujifilm S1 PRO through carelessness – not related to the actual modification.

See my warning at the bottom of the right hand column on this blog regarding doing anything I describe on this blog. In this case, maybe I should have read it myself

Long story-

I noticed the thickness of the original mount on the S1. It eyeballed with a rule as ~2.5mm. Then I compared it to the thickness of the M42 to Nikon F mount adapter that I recently purchased. It eyeballed at ~1mm. This meant, if all went well, the 1mm difference between the registration of the Nikon F mount and the registration of an M42 lens would be more than made up.

Since the plate is held by only 5 screws, I removed it. The adapter appeared to be able to fit in the original mounts place if the electronic contact piece was removed. Two screws and a small pry later that was out of the way. Yes – the adapter fit nicely in place.

Using the original as a template, I drilled five holes with detents for the screw heads in the adapter. Then I put three of the screws in place, took a picture and proceeded to put the remaining screws in place. Disaster struck when the screwdriver slipped on the fourth screw. The tip of the screwdriver hit the shutter curtain leaving a small dimple. I figured that it wasn’t a big deal and finished the mounting.

I took a couple shots inside (it was around Midnight) to check close up focus and then put the leash on my Yellow Lab and went outside looking for something bright enough to check infinity focus. A store a few blocks away with a nicely lit up sign gave me that opportunity.

Returning home, I downloaded the TIFFs onto my computer and did a quick look. OOPS! (not really what I said) There was a huge black spider web in the images. Assuming what the problem was, I proved it by opening the shutter as if I was going to clean the sensor. Yup, the cover over the sensor was smashed.

Bottom line –

The actual modification works. The two images with the spiderweb were taken with a cheap Tamron 70-210mm M42 mount via adaptall. The closeup of the digital clock was approximately at a distance of ~7 feet, the sign at a distance of ~400 feet. In fact, the lens actually focused beyond this distance.

NOTE: Make sure to have the M/AF switch on the front of the camera near the lens release set to M to ensure the focus motor doesn’t try to operate.

Being a klutz ruined the camera. Please read my warning referred to above before attempting this yourself.

In retrospect, since this was to be a non-reverse able modification anyways, if I were to do it again I would simply use a good brand of gel super glue in the place of the whole drilling of holes and use of screws to hold the adapter in place. (read the disclaimer)

Spring Is Here ! At Least Until Tomorrow …….

Return To Homepage

We got a reprieve today. Last night the forecast was for 1-3 inches of snow and overcast for today. The snow did not fall and the Sun has been out all day. I took the time to take a few pictures with my Canon XTi with a Sears 50/1.4 M42 lens mounted with an adapter.

These were all taken at f1.4 to try out the small depth of field. I guess I am not going to have to spend money on a new EF Canon 50/1.4 lens. The Sears lens had been pushed into the back of a drawer after I compared it to my Canon EF 50/1.8 metal mount in relation to the additional brightness available. I just never considered using it seriously for actual photography. The DOF difference and the brightness have made me a believer, also it is nice to have a metal lens.

Anyone know the years of manufacture/sale for the Sears lens? Also, what company manufactured it ?
