Answer: By design we can avoid the use of the filter in non-wide angle lens will not have dark corners, if your focal length is less than 24mm still may back to produce. 

Dear K&F customer,We have warehouses in DE,UK,US,AU,CHN. We need to see what you are buying, and check the inventory of the warehouse where you choose to ship. Logistics delivery time depends on which country you are sending to. If the product you buy is in stock in our overseas warehouse, we will ship it directly from the local warehouse. But if the product you bought is not in stock in the local warehouse, then we will ship it to you from other warehouses. If the goods are shipped from a local warehouse, the logistics time is about 3-7 days. To ship from other warehouses, it will take about 3-15 days. Because of COVID-19, the efficiency of logistics will be slower than usual, please don't worry. I also notified the logistics company to deliver your package as soon as possible. 

I have the 77mm version of this and I am NOT able to use a lens hood on my Canon 17-40mm wide angle once the filter is on. I haven't tried putting on the hood first and then trying to screw on the filter yet. That's not to say that all lens hoods won't work but for me it does not under the scenario described above. 

you said (Tamron 77 wide angle lense?) the lens info can't be right! do you have the full name of the lens.
