Diamond 0.3x on HC40

[sdctlc 0]

Has anybody tried the diamond lens on the 25mm thread HC series. I know poeple have and are using it, I am curious if anyone HERE is using that. The 25mm lens is so small I know they claim no sidtortion but it seems so small at 25mm. Alternatively has anyone put a 30mm Diamond 0.3x lens on the 25mm camera with a Step ring..

thanks

Yes, and it worked great.

Rob,

Are you using the 25mm thread? or a larger one with a step ring?

I use the Diamond 0.3 on an HC 40 (25 mm thread) I like it because I can fly real close to tandems, but I don't like the fact you can't use a preset (like landscape) for focus. If you do it is blurry. The auto focus doesn't allow you video a landing tandem at altitude over 100 feet very well if you keep the camera on your head. If it is off center in the slightests it will lose its focus on the tandem under canopy.

or am I missing something?

PLUS: Great wide angle shots w/o vingetting (sp?)
MINUS: Can't use preset focus on HC40

Steve,

There is no "Diamond 0.6". There is a Diamond 0.3 and a Stealth 0.5. I have a Diamond 0.3, but as I described in this thread, I actually measured the FOV of my lens, after hearing many reports that not only does effective wide angle vary relative to the nomenclature of the lens, it also varies dependent on camera. I use an HC90, and I measured the effective angle of my lens at ~0.4, and I can zoom in to ~0.8 before it starts to get blurry. So my "0.3" actually is a "0.4-0.8". This is all obviously using my camera's default, unzoomed FOV as "1.0" baseline.

I usually use it at about 0.7, with my HC90 (similar to HC40, major difference is larger CCD). I have no focusing problems. I'll describe what I do, which I read on here somewhere. On the ground, aim the camera at something about 15 feet away. Change focus to auto. After it focuses on the subject, change focus again to manual. The text "0.1m," will appear on the screen (in my experience, at least). That's it, you're set. Everything from zero to infinity is now in focus. That has worked for me like a charm from my first video jump... I've never tried another focusing method. Have you tried that?

Oops, I can spell, but I can't type (generational thing as typing was for girls back in my day.) I meant I have the Diamond 0.3

No, but I will -- I'll let you know how that works out -- thank!

You may also want to put the camera in the "sports" setting. That is what I use and have had no problems with AF. (I have a Kenko .5 and a Cokin .5)

A kenko will not be blurry, (I have 2 of those) but a Diamond 0.3 will. I will try what Matt said to see if that works. I do know if you merely put the Diamond 0.3 on set the camera with sport or landscape setting it will be blurry. I lost a coach jump video I did that way by assuming it would work just as the Kenko did.

Both, but if you have a choice, buy a lens with threads that match the camera.
Stepper rings are available - cheap - from royal lens.
