Is it a Contax or a Yashica lens? If the Yashica 28mm, this is the lenshood:

That looks like the one my TLR .
It looks deep for a 28mm .
I use metal screw in wide angle hood for my wife angle lenses that don't have a dedicated hood .
They work fine for me .
All lenses I have that use bayonet fit hoods all have the OEM hood .

Good eye! I had a filter on the lens, but I removed it and put the lens on my digital camera and still have some vignetting even without the filter

Do you have vignetting without the hood?

Over the years I’ve noticed a significant change in those rubber collapsible lens shades and stopped using them. Barely suitable even for normal lenses in the past 20 years. Now using metal screw-in hoods for all of my 35mm lenses… tested, of course, to verify that they work better.

Actually I'm mistaken. According to the user's manual, that Yashica branded hood is only for the 50mm lens.
So, I don't think Yashica made any lens hoods for the wide angle lenses.
Not sure about Contax; I don't have any Contax lenses.

I use Konica, Pentax, and Miranda slip on hoods matched for 28 and 24mm lens. With a slip on I can use most filters, narrow or wide without any vignetting, the only time I have a issue is when using a polarizer. The Yashica branded 28 looks like a slip on as do the slip on for the 50mms.

Here's the Contax G-12 hood on a 28/2.8 Distagon. Filter size is also 55mm and there's no vignetting, but without a filter mounted. I don't recall it being too expensive (maybe $20-30) but I'm sure there are sellers who will ask crazy prices because of the name. Many cameras only show 92-97% of the full frame in the VF, so that's not a reliable way to detect any vignetting.

Lol this is getting heated! I've always been one to find the generic brand just fine...

I have a similar collapsible hood like yours. When collapsed mine appears to lie flat with the lens like yours and seems as flat as another non collapsible generic and cheap one that I use without problem with my 28mm lens. The Yashica/Contax proper wide- angle hood looks as if it stick out just as far if not further that your collapsible hood

Clearly you have a problem with vignetting otherwise you would not have started the thread and everyone else is convinced that you need to buy the proper but expensive lens to correct it. If you have the money to spare then fine but my instinct and my experience with my generic and cheap, rubber wide-angle lens is that if the collapsible one does not work a generic wide-angle one should. It does for me

The manufacturer provided lens hoods for zoom lenses are designed to really only completely shade for the shortest focal length. There is a message in that.
