Yes the Hoya +4 72mm is a single-element close-up filter. So I think it won't be the right product for me. I think I'll buy a Raynox DCR-150. Can you get good results with the DCR-150 at any focal length like the DCR-250?
Yes. Until I switched to using a macro lens the year before last a Raynox 150 was my most used close-up lens for invertebrates for over 10 years. (I also had the Raynox 250, Canon 500D and 250D and the Marumi 200 and 330, but the Raynox 150 worked best for me.) I used the 150 with no problem on my bridge cameras at all focal lengths apart from the shortest focal lengths that produced vignetting.
Why did you start using a macro lens instead of a close-up filter?
So I could get greater depth of field, especially for small subjects such as springtails like this which are perhaps 2mm long.
Wow! Amazing shot!

Which macro lens do you use for photographing insects?
This is the setup I use.

Do you consider the working distance enough?
Yes.
I asked because I would usually get a shorter working distance with a DSLR than with a bridge camera + Raynox. The DSLR + lens is also much heavier and harder for me to take pictures without a tripod.
A couple of weeks ago I read that if you use a teleconverter, you can get more working distance. You have just showed me that! I will definitely try my teleconverter + extension tube (my lens is EF-S and it is not directly compatible with the Canon teleconverter).
I will also test my Raynox MSN202 with a much smaller aperture to get more DOF.
Thanks for inspiring me to try new things!
I noticed that the Canon 250D does not work very well with focal lengths longer than 135mm.
I wasn't at all happy with the image quality from a Canon 250D, both the one I have now and the one I had before but sent back because I thought it was faulty (but the later one was no better).
I wasn't happy either, so I rarely used it. Now I know that it is good with a lens up to 135mm.
I don't remember what focal length I tested it with, but I wouldn't expect the problems I saw to go away with a different focal length.
Did you like the results from the full frame lens + close-up filter?
I'm afraid I haven't used it enough to know.
Thanks for sharing your knowledge!
You are very welcome.
