EF-to-EFM Adapter again.
6

About a month ago, when I asked in this forum which 3rd party adapter was good, someone answered that Fotodiox and Viltrox would be good. So I ordered it from China (actually 6 weeks ago) and I got it today finally.

At first, nice case

Nice package. It has a certificate and manual!

Nice looking.

It looks good although it is lighter and its finish definitely looks cheaper than the original Canon adapter.

AF works beautifully with all EF/EFS lenses that I have. Not a problem. No complaint.

HOWEVER, it was not long before I found a problem.

.

Look at the photos. All were taken with EF 50mm 1.4 at F/4.

Viltrox Adapter

Look at the strong flare!

First I took off UV filter, which is of B+W.

It was not a solution. Then, I made an additional hood at the right side of the lens with my hand and got the following. All photos here are taken with my 50mm attached with the original hood.

Viltrox Adapter + Hand

Then I switched the adapter back to the Canon original one.

Canon Original Adapter

The problem is gone basically although the image is not clear enough.

One more with a hand hood.

Original Adapter + Hand

Now better.

IMO, it is due to the inside material with a glossy finish. I do not understand that a photography company is making such a product. They seem to care about their package, but not about the quality.

.

Today I found the following reply:

I should have waited for this reply or read all replies carefully.

Do you have any idea how to paint the inside with a black unshiny paint?

Do not follow my step. No Viltrox adapter.

Re: EF-to-EFM Adapter again.

I don't know how the interior of the adapter looks, but if there is room, consider using flocking material.

Budget route would to buy these black elbow/knee pads cut to size and glue it on.

Re: EF-to-EFM Adapter again.

Yeah. I've been trying to warn people about these issues with Viltrox/Vello/Fotodiox adapters.

All these alternative brands have the same manufacturer as their source and they produce the same problems.

The glossy interior reflecting light into the lens and producing these weird flares can totally kill a shot, specially at night and interior scenes where every lamp or source of light becomes prone to this problem.

I've returned a Viltrox and a Fotodiox adapter because of this. And had to sell my Vello one which I had bought some time ago and couldn't return it anymore.

Re: EF-to-EFM Adapter again.

I've never heard of this issue before and have not experienced any problems with the Viltrox EF- EF m adapter that I have. Do you have a picture of the inside of your adapter that you could post ? My adapter while not Matt on the inside has a slight satin finish so not sure if it's the same finish as yours.

Test with a tele lens (50mm or above).

I was able to replicate it with a 50mm STM, a 85mm f/1.8 USM and a 17-55mm f/2.8 (at 55mm).

I'm sure you will be able to replicate the issue.

In a indoors situation, expose for the room and then point the camera to a light bulb and play around. You'll see this hard edge flare thing appearing.

I've only used it mainly on my 55-250mm STM and 40mm EF. I'll see if I can replicate it at some point in time and report back.

I found another guy who is saying the same thing. Even though Viltrox looks similar to Canon in many ways, it still delivers a serious problem.

I hope you can see the difference.

You do not have to use tele lens. I found this for the first time with 17-40L.

55-250 will surely reproduce the same issue.

Thanks for posting the comparison shot.The inside of my Viltrox has a similar sheen on the inside but thus far I have failed to replicate the issue so I'm not going to worry about it.If the issue ever does show up in future at least I'll know the possible cause.That said the quality and design of the adapter in the linked article does seem a bit dubious.

Same here, haven't experienced any issues and mine also has a satin finish which isn't totally matte but also isn't shiny.

I was worried about these issues that I read here but I went ahead and bought the Viltrox because the general consensus was that it was one of the better options for that price point, just wanted to let people know who are looking at the Viltrox that it seems to be a good option and doesnt have much play at all like some of the cheaper adapters have.

Re: EF-to-EFM Adapter again.

Just wanted to add my recent experience with the Viltrox adapter in case it is helpful for anyone. At first, adapting the 40mm and 50mm light EF lenses it worked great, no issues. But after a few times mounting a heaving Tamron 70-200 2.8 I started to notice some give/wobble in the fitting. This quickly got worse. Now when I use the 70-300 (not the L one) it very easily move a little resulting in a 'lens error' message, which requires not only turning the camera off but also taking the battery out. Shooting wildlife yesterday for 30 mins I had to do this about 7 times and have to hold the lens an awkward way to avoid it. I didn't want to risk trying another 3rd party adapter so bought a 'like new' used one from ebay for $110. It's a shame that Canon charges $200 for an adapter without any glass elements, pushing many people to 3rd party can give a worse experience of their camera products.

Regarding the flaring i don't remember ever seeing this when I was adapting 40mm and 50mm EF's. But with the 70-300 I do se it, but am not sure to what extent it is just the lens that doesn't deal well with flaring.

Before the release of the R mount, you could get New Canon adapters from Ebay for 50-75 and refurbished from Canon for $50.

Its a shame they limited supply and stopped kitting adapters with cameras. I suspect these will become even more rarer as supply really dries up.

There is another used one on ebay for $120

Re: EF-to-EFM Adapter again.

Have a cheap Meike one.  No flare. Very odd how OPs is giving that level of flare and vast majority of people clearly aren’t getting it (not like you wouldn’t notice!).

Have had a guide scope for my telescope with the same issue.  The guide scope itself was fine, but the inside of the focuser was shiny!  Thankfully had flocking material left over so it was an easy fix BUT it’s ridiculous that anything like this should be made!

I use the cheapest of all

I own the Meike adapter, paid around 29€ for it. Have had NO complaints whatsoever

Re: EF-to-EFM Adapter again.

FWIW, I have the same adapter from Viltrox. I've had zero problems with ef50/1.8, 85/1.8, 70-200/4L.

I got Viltrox adapter last week, brand new and sealed, but when I tested it, it have wobble on both ends, with camera and with lens.

So I have to send it back and lost some money on transportation, so I will got Canon adapter instead.

Re: EF-to-EFM Adapter again.

I've had the Fotodiox lens adapter for 14 months not a single problem in the time.

I'll add my test to this thread...

Fotodiox Pro adapter. Veiling glare and loss of contrast present.

Canon OEM adapter. Much better.

Canon OEM adapter.  Much better.

With the Fotodiox Pro, brighter areas scatter light into the darker areas.

They both "function" the same, it's just the results that differ.

Thank you for this.  I picked up the Fotodiox about a month ago but have not had time to use it with a real camera lens.  My use will be with a 100mm macro lens for indoor fun.

Actually I picked it up as I first ordered a $15 T2-EFM adapter for my telescope and it did not lock on camera (see this DPR post ).  I figured for $25 more I might as well get the adapter as I already have a EF mount on the telescope.

I hope it should be OK if the scene does not have light sources.

I wonder if the inside could be sprayed with a matte black paint.  Yeah, unlikely to be possible without drips and blobs.
