Anyone used this on an SMC Takumar 50 mm f/1.4. At infinity, the rear lens protrudes back and the adapter flange prevents it from focusing to infinity

Goodmorning. I have used this adapter on my SMC Takumar 50 mm f/1.4 on my Canon T3i with no problems. The lens only protrudes beyond the flange maybe an 1/8 of an inch. In fact it does not even protrude beyond the auto focusing contacts shelf (for lack of a better description). the Adapter is designed for the Modern Canon products. If you are using it on a camera that is older or one that does not have a Single lens Reflex (SLR) design this might be a problem. I would also take the adapter off to make sure the problem is not with the lens itself. It would be helpful to know what model/year Canon camera you are using to further understand the difficulty that you are experiencing. Goodmorning.

Update: I have looked at various SMC Takumar lenses on Google images and now I think I have a better understanding of your problem. Not all SMC Takumar 50 mm f/1.4 lenses are created equal. My lens is of and older origin. I have seen in pictures of a another SMC takumar lens that seems to protrude more in the back. I think this is your problem. If you have the "Late" version of this lens, then yes is it may not work. You are going to have to buy a earlier version of this lens , around 1961-1972? I'm not a lens expert, but it looks like the lens that you do have will not work with this adapter, unless you take it to a machinist and have them widen the internal diameter of the adapter it sounds like. (It may not be much.) Pentax through out the years kept changing designs of their lenses like most companies to take advantage of more "Features" and "Auto" settings. Sorry you are having problems. I wish you all the best luck with this! Bryan

The adapter I have was very tight at first. I removed the assembly from the camera and had to use a considerable amount of force to get it to come off the first lens I put it on. Just MAKE SURE the small release pin on the side is pulled back (to release the locking pin) before trying to rotate the adapter when removing it. Be careful not to damage your lens. Best of luck.

I have used the adaptor with 50mm f/1.2, 85mm, 35mm, 16-35mm,24-70mm, 100mm, 70-200mm and 100-400mm and it didn't make any noise. The problem could be you're having a defected adaptor or damaged lens contacts. In general, the adaptor works perfectly well.

That's a good question! I've had issues with infinity focus with this item it's worth a shot though I think:)

Not is a problem, is normal. Adapter complete is for telephoto (extended lens). Half adapter, without final part, is for wide angular (compressed lens). Tunnel effect is present if you use the adapter without this considerations

Hi Rhonda....I too found the adapter difficult to mount just due to the close tolerances. However, forcing it is a big no! no!. After gently twisting and making sure the piece was level with the barrel of the SX50,it slipped on and with just a nudge secured itself tightly. Never had a problem since. You just have to be patient, but I guarantee you it does work as it should. Thanks, Mike

It will absolutely fit! I picked up a Fotasy FF2B and I love it. And for any follow focus, especially if you have a lens with a small focus ring, I suggest scrapping the gear band they send you to attach to the lens, and instead just wrap the ff gear with a piece of mounting tape and fit it up against the lens focus ring directly. It's so much less bulky, and turns as smoothly as if you were focusing by hand.

Are you going to use it on a sony body? how long is the rear element? I have only tried de 35mm and 75mm Summilux on a Sony Nex FS 700 and they were fine.I did not try the 21mm superangulon which has a longer rear element. For $20 if it does not work it will not be a tragedy.

P. Hudson,I made it look confusing. I think the lense thread is 60mm. The adapter would be 60mm to 67mm to accept the 67mm filters. That's the best guess I can come up with.

Sorry, I have not used the lens or camera you ask about. The manufacturer should have info on infinity focus on their site. Good luck.

Hi. The issue to keep in mind is the distance from the outer most Canon extender lens surface to the Bower telescope recessed lens in all the available lens extenders (lens magnification multipliers). In this case I have to advise not a good idea as they will not match up. I do use an extender multiplier lens adapter made by Kenko, C-AF 2X Teleplus Pro 300. I have used it with all my Canon lenses and the Bower lens you are asking about. Remember, you will also need an adapter ring to match the Bower lens to the Canon camera or extender. When ordering the Bower lens you will need to pay attention to which adapter ring is being offered as they list it with different adapter rings for sale on Amazon.com. Additionally, when looking at other than Canon lens extenders (2x) be careful with the issue of lens depth as you match one lens with an extender. The Kenko 2x lens extender does allow room for Canon lenses to fit. Hope this is helpful. If you have any other questions just use the same system to write. Without saying, putting a 2X extender on a 600 to 1300 mm lens will make it very difficult to focus on an image unless you have a really good tripod...heavy duty and expensive. One with adjusting gears will make life a lot more fun. Good Luck!!!

I never had a problem with lens flare with this adaptor. I used it in conjunction with a NEX 5 R using a Tamron 18-250 lens. It worked good but I realized that I lost some control over the lens as this doesn't allow you to use any f-stop control at all so if you are planning to use this to take critical shots that need f-stop control you won't be able to do it that way.

I've totally forgotten since I sold mine with my long lens. Sorry. I can say that it worked well with both my 300mm 500mm.

I also had trouble at first. There is a metal tab on the interior of the adapter that you have to push in to get it to "lock." You may need to use a small screwdriver to hold it down while placing it onto the lens. Once it's on you'll know.

This lens, DCR-2025PRO, I just bought for my Fujifilm X-S1. It works exellent with this kamera from fokal length from abouth 250/300mm and up to 624mm. This gives my camera å total fokal area from 24mm to abort 1370mm, or 57,2 x Zoom. The results of my testing so far is very good and I got som very crisp and detailed photos of the moon (as an example). I don

Hello - it didn't work on my 28mm or the 35mm OM lenses. I expected it wouldn't for the 28mm b/c it had the shield that protruded from the rear of the mount. It worked on the 75-150mm since it didn't have the shield.

Mina, I've noticed that these adapters fit really tight to the zeiss lens. I use them on several different zeiss lens and they all are tough to get off. With the rear element of then lens facing you, you might notice the small release pin that sticks out slightly. It's like a little price of metal that sticks out (towards the inside of the adapter ring). The idea is to gently push that in while twisting the adapter. It should come off. Just make sure that you are twisting the correct way. It's a little snug, so you will have to twist a bit more that you might like. It's nerve wracking the first time.
