Samyang 35mm F1.4 UMC

Still working on the chip... I had the focus confirm and was able to program it, but it was off slightly, only read the chip when the lens was turned a certain way, so I tried to move it a bit, and long story short that ruined its reading, so I'm trying all over again.... I'll have a blog post on a how-to if I ever get it...

Edit, just got it 100%, I don't think it got the focal length programmed right, but whatever it has the max aperture correct and it gives me focus confirm beeps. I had to Micro Adjust it -20 but I'll keep playing iwth that and see, it works well though, Now I just gotta baby the lens even more to make sure the super glue doesn't break at all...

Here is the lens after being chipped
NOTE: taken with the 50 1.4 NOT the 35 1.4


Here is one of my first shots using the AF confirmation beep/light, I had to MicroAdjust for backfocusing quite a bit, I'm gonna check that out more later but it looks pretty spot on now to me...

Creative shot.

[Gryphes]

Been raining for weeks so I'm going a bit crazy being locked up inside all day. Nothing special just really bored and needed something to shoot.

Love that pic Chumlee, I do however think you're taking shooting with a lens to literally lol

[chumlee]

Thanks Guys!

All of the shots on the last few pages have been great.

I have double sided tape, normal tape, Krazy glue, and poster puddy. So far this mounting chip thingy is still driving me crazy. First time I tried it I didn't realize the white peice Tagotech sent is to line up the chip with that little dip on the adaptor ring (if that's the proper term for it) And I still have no clue what the tiny black prices of plastic are for.

The second time I ended up. Buying two more chips, and this time I unscrewed the mount to make sure I didn't accidentally drop the chip on the glass element itself. But im a bit confused on what those black bits of plastic are for. Anyways I was able to line it up, until I connected it to my camera (do not use poster puddy or foam board). I turn on my camera. Noticed my Fstop still showed F00 (I thought it would have showed something), and half pressed the shutter while turning the lens in either direction and nothing lights up. I'm sure I'm not mounting it properly.

Now my two chips are sitting on my desk still in their plastic bag. It would be super helpful to have an overly detailed how to lol.

ok here are the steps i followed this morning:
1. unscrew the mount from the lens (place screws in a secure place)

2. Place the mount on the camera and turn it until it locks. (similar to mounting any other lens)

3. Take black sharpie (or any other color) and mark the location of where the chip needs to be. I marked it on the black lined cylindrical area that goes into the camera.

In order to mark the black area, place the camera with the mount attached, on to a flat surface and look at it directly from the top of where the flash mount is on the camera. All the contacts inside the camera should be visible. All you have to do is mark it.

A note, marking doesn't need to perfect because the contact area on the aftermarket chips are way bigger than the contacts inside the lens.

4. After marking, take the mount off the camera.

5. Here is where it is going to be trial and error. The AF confirm chip I had was really short. Once I mount the chip in the location on the mount and place the mount back in the camera, the chip was in the right location but was not making touching the contacts that were inside the camera. AS a result the chip needs to be raised off of the mount.

Here is what I did.

6. I took a butter container that we threw out this morning, cut the lid exactly the same way the chip is (a bit of plastic towards the inside of the arc is ok. The critical part is that the outside of the arc of the chip and the plastic need to be in line.

7. I used super glue to attach the cut plastic piece to the chip. Once that was dry, I glued the chip to the mount in the same sharpie marked area.

8. Once that was dry, I place the mount back on the camera. Viola! The chip was touching all the contacts. (this can be seen because as you attach the mount to the camera, all the get pressed in slowly. Look at the contacts from the top view like you did before to mark the mount.

After the success, I placed the mount back on the lens, mounted the lens on the camera and worked like a charm.

Hope this works for you guys. If you need pictures let me know.

Oh wow, I will totally give it a try later on! Thank you ThaShef

What he said^ I had to raise mine up aswell, using clear plastic from a plastic container. Then It wasn't lined up 100% correctly, I had to turn the lens 100% of the way (even after the click) for it to register the aperture. So I had to shift it over.

instead of doing the sharpie method on the camera, I would suggest just taking one of your other lenses, laying your chip over the chip on the lens and seeing what part of the chip lines up where with the lens mount using the metal bracket shapes as a reference point. It will take trial and error, I strongly suggest having some non-acetone nailpolish remover for removing the excess glue. programming can be kind of a pain, mine still wont get that its a 35mm lens, not a 50, but it has the aperture setting and MA settings right

[Bond_Savingsbond]

Bad news (for now I guess). Apature ring is now stuck at F22

During a photoshoot right now I noticed my lens was wobbly on my 5D, so like a peeling scab I played with it. Moments later I watched my viewfinder fade to dark. So I guess the chipping will have to wait. When I get home I need to find the warranty card and send this baby off to the doctors.

So the rest of my shoot will be with my 50

[paradiddleluke]

have you taken off the mounting bracket? It is a rather easy fix if the aperture ring isn't changing the actual blades... happened to me, I can walk you through it if you need... but I respect if you would just rather send it off to the company.

[Bond_Savingsbond]

I'm on my way home to upload the pics. And if you say it's an easy fix, I can give it a try.

[paradiddleluke]

I'll try to walk you through it, and I'll post it in this thread incase anyone else has this issue.

First step, unscrew the mount, you will see a circular metal piece, this piece has to be aligned properly for the aperture ring to actually change the aperture. it can fall out of alignment very easily, because the aperture blades are spring loaded, it will lock at its smallest aperture.

NOT TAKEN WITH THE 35 1.4.... Here's the piece


Once you have the mount off, focus the lens so that the glass goes as far into the body of the lens as possible, it isn't 100% necessary but it'll protect your glass a bit more.

Quickly turn the lens over, the metal circle piece will fall out, make sure you either catch it or have it fall onto a soft surface.

Once the circular piece is out, you will see a few yellowish metal looking pieces, one that is sort of a latch and one that turns when the aperture ring turns. At this point, turn your focus ring so that the glass on the back is as far out of the lens body as possible, this will raise up a small silver metal pin that you can move, this controls the aperture blades.

Once you've found all the pieces, Turn the aperture ring all the way to 1.4. The metal ring you took out has two little metal pieces on one side that conveniently slide over that silver pin, and on the other side has a little pin of its own.

Slide the two metal pieces over the silver pin, and without putting the metal circle down, turn to the right, this will open the aperture blades up.

You want the pin on the circular ring to be on the LEFT side of the yellowish metal latch, if it is on the right, it won't change the aperture.

If you think you have got it, the aperture blades should be fully open, turn the aperture ring to 2... if you see the blades close a bit then you have it on right.

NOTE: the metal piece gets knocked off very easily, so when you test if the aperture ring works I suggest holding a finger on the metal ring to make sure it stays down.

If all is well, carefully put the metal lens mount back on, making sure that the aperture blades do not get locked closed again.

Hope this helps, wish I had taken pictures while I was fixing it but to be honest I was freaking out so much photos were the least of my worries.... haha

You are a lifesaver! I'm wondering if my second attempts when I tried to chip the lens (I took out the metal mount, but never tipped it over) caused it to become loose.

Now for Chipping round 3 =/

[paradiddleluke]

Glad it helped!

I FREAKED OUT when I thought I had broken my lens, hahah so I'm glad I could help!

Good luck with your chipping!
