EF to EF drop in filter adapter?

[truelies]

I think this is the best solution on filters for all EF lens, don't know why canon haven't make an adapter between lens & body like EF-RF?

[kvbarkley]

He wants an adapter to go between an EF lens and EF body which has a drop in filter holder. Like this EF to RF adapter:

Depends what you're doing. For my typical photography, filters are VERY important.

No one is staying that everyone needs to use filters, but for some people they are indispensable.

"For my typical photography, filters are VERY important."

For instance like what? Excluding the polarizer, as mentioned, and possibly an ND, I am curious of your "VERY important."

ebiggs1.....Why do you need to argue about the poster's desire to use filters?

I do a lot of astrophotography. Filters can make or break your ability to capture certain objects.

I do astrophotography. I use 2inch dual narrowband filters to cut out light pollution and moonglow. I also use CLS and quad-band filters for light pollution. While the 2inch filter can easily screw into my telescope, and most telescopes in general, I am also trying to find a drop-in filter drawer that will mount to my T3i which has an EF mount and allow me to connect my EF lenses. There are plenty that adapt from EF mount on the body to other lens mounts or that connect EF lens mounts to ZWO cameras. Just because some of us have different needs for photography, we dont need any of your dismissive and arrogant responses. We are just looking for advice and checking with a community that may be more knowledgeable than we are. We are very aware that astrophotography is a very specialized and niche (and expensive) field of photography. It is hard enough as it is, and we shouldnt be interrogated based on your feeling of superiority and disbelief. I mean jeez, you are such a guru of photography, how could anyone need something that you dont. I am sure you are the gold standard of photography, but you can just give us advice if you want or say you dont know or not even respond. I hope this answers your question of why anyone would need filters, since YOU dont use filters.

Unfortunately there's not going to be anything that can go between an EF mount body and an EF lens that can hold a filter without changing the optical properties of the lens. Even then, the only things are the EF extenders and they don't hold filters, as I'm sure you're aware. EF lens to RF body, sure, due to the differences in the flange distance requirements for each mount.

Your best option to use filters on an EF body with an EF lens is clip-in filters.

[ebiggs1]

Not arguing but for the large part and in fact filters are obsolete. So if there is no real purpose you don’t need them. Except for a very limited situation Photoshop can do the same effect and do it even better

[Kla3271]

Ok. Thank you. I had purchased a 2 inch dual narrowband filter and was hoping i could find a way to use it with 135mm lens, but oh well. I reckon my lenses will just have to stick with my clip in CLS filter.

Not everyone has, needs, or wants Photoshop. If a simple drop-in filter can provide a special effect, right on!
