Is it true??

Hey guys,

Is it true that you can't zoom in at all with a royal lens? I have a .25 way cool lens and I can zoom in almost to half way before it gets blurry.

If so then why is it possible with a way cool and not a royal.

No single element lens are considered as zoom-thru lenses. You can zoom, but the backfocus won't work. In other words, you can zoom through both single element lenses, but the focus point will be different at every point in the zoom.

Royal lens .3 will act identical to the similar way cool piece. It'll zoom half way then get out of focus

Could a person use a .3 and zoom it some for fun stuff, 4 way etc?

Mostly, your friend is correct. He should be able to get approx 10% of the focal length, it'll vary from cam to cam by a small amount.
I don't get a zoom halfway through my Waycool, either.

Yes, i use Royal Lense .3

Like i said, using Royal Lens .3 on a Sony PC1000 or Sony HC3 you WILL be able to zoom in half way (or even a little more, if you do it slowly) before it cannot focus anymore. Use Auto focus and zoom in SLOWLY.

This will vary greatly with different cameras. With an HC1/3/5/7, or the Sony CX7, you won't get more than 10%.

And with the Sony PC series (105, 109 family) it will zoom in half way (approx).

AFAIK the royal and way cool lenses are to all intents and purposes the same thing.

as i wrote above, I am getting (more then) half way with Sony HC3 and Royal .3 Try using your zoom slowly and allow the camcorder time to keep the object in focus.

I have. Just did it again to test it, based on your post. Previewing out HDMI from the HC3, monitoring on a Luma broadcast monitor, manual and/or auto focus cannot display the centerpoint in a backfocus chart. It's soft. I can see how someone might believe it's in focus, particularly using the camera display panel, but it's not actually focused. I suppose it could be said that focus is a relative concept?
