Hi,

 

I am using the rx100 m4, now I am considering to buy a close-up lens for taking fotos of small thing. I can get a Dyron +7 from a friend for a good price, is Dyron a good company to choose?

 

I want mainly take fotos of middle sized nudibranch, is +7 enough with rx100's 24-70mm?

 

Thank you!

I never used a Dyron lens, but heard good things about them.
I use a SubSee +10 on my Nauticam Panasonic LX-100 rig and it works great but is picky about micro unsharp because of camera movement
As tronger the lens is more you need you need very good buoyancy, a lot of light and calm water to archieve sharp shots.
Also a focus light to help your autofocus to focus on the right point as DOF is very limited.
Shoot F16 and at least 1/250sec to obtain sharp images

If you can get it for a very good price then buy it, otherwise opt for a less strong lens

 

Try it first on your camera/housing combination to see how much zoom you need to get sharp images and elimiate vigneting
