Be careful of what you order, it may not be what you need!

On December 7, 2020 I placed an order through EBay for a camera lens. I ordered a Tamron AF 18-27mm F3.5-6.3 Di II VC PZD lens. It arrived On December 11, 2020. Before unboxing the item I checked the packing slip. Everything matched. I opened the box to find a lens in pristine condition as described.

I mounted it on my Canon 5D Mark IV and lo and behold. The image had a major vignette issue. This lens is intended for a Canon camera with a crop sensor.
The “Di II“ suggests for use with a crop sensor camera. Oops, I goofed up.

Can you not return the lens, at least for a credit against another purchase??

Buying something unknown is always a good time to get an education. At least being a non-Canon brand crop sensor lens, you can actually use it on your body. What you see in the viewfinder is what you will get, simply crop out the vignette.

The EF 16-35mm f/4L IS is a wonderful lens and appropriate for a full-frame body.

We're talking eBay here. I've been burned too many times on eBay and they have not customer service.

I have used a Tamron 10-24 for crop sensor on a FF 6D body, starting at 14 mm the vignette was almost un-noticeable.
But of course I bought the lens for use on a 7DII - big discount sale if you bought a Tamron lens with the body.
I loaned that lens to my daughter for an Anime/Cosplay event and she fell in love with it on her T2i. So I gave it to her for her birthday. When I want wide angle on my FF bodies I have a 14 mm f/2.8 and a 24-105L f/4.

Likewise in using a Nikon 10-24 DX on various FX cameras. Verrrrry handy.

All my research so far tells me that a Z series camera will refuse to allow that, switching into DX format with no option to manually override it. Any actual user reports to the contrary will be received as great news !!!

I plan to return it. I hope for something of a full refund minus shipping. I was not aware of a few things. I chose the 5D body because it has a full frame sensor. I wanted to have a lens with a good range just in case I get tired of carrying four pieces of glass as I usually do.

I didn’t realize Tamron lens has the nomenclature already listed for a crop sensor. Meanwhile lenses from other manufacturers it would be indicated with EF-S. I also wanted to take a moment to let other Hoggers be made aware that the markings on a Tamron lens outer ring may not be clear as to what kind of sensor is required.

I wonder if all third party manufacturers of lenses have this type of nomenclature in place. Is this true of Sigma lenses?

Only Canon has the EF-S designation, being actually the mount based on the white square rather than the red dot alignment. All the third-parties align at the EF mount's red-dot and include in the lens name a brand-specific code to indicate coverage for the cropped sensor. Reviewing a major seller's site for the lens in question is one way to avoid the issue. Using genuine Canon equipment is another.

Lenses from Third party manufacturers are usually significantly cheaper than name brands. I realize I need to do more research now because the Canon service Mark is only on Canon lenses. So I did a little research.

Tamron:
Lens Designation Camera Sensor type
Di Full Frame
Di II Crop Sensor

Sigma:
DG Full Frame
DC Crop Sensor

Rokinon:
Will specify according to Canon Design.
EF Full Frame
EF-s Crop Sensor

When buying something on eBay, it is wise to do thorough research to make sure the item is exactly what you are looking for. Generally you are only entitled to return the item if the seller gave misleading information about it in the description, or it got seriously damaged in transit.

I am aware of their policies. I am in contact with the merchant. I am claiming that the lens did not indicate it was for a crop sensor camera even though it was listed as a Sigma Di II. Also, the focusing mechanism was sluggish and
non-functional.

Note Rokinon is one of several names put on lenses made for different distributors by Samyang in So Korea. All the same lenses with different names. I have one of their 14 mm f/2.8 Ultra Wides with the name Bower on it.

I was not aware. I actually thought Rokinon was a separate company. It can become very easy to select a lens only to find out it your camera.

Rokinon is the name of the major US importer's lenses. But they are made by Samyang.
