GH1 Fisheye/Wide-Angle Lens/Adapter Recommendations for GH1?

My brother wants to do some filming of him and his friends skateboarding with the GH1. I said it's fine, but he has to buy the fisheye/wide-angle lens/adapter.

He can't afford the Olympus 9-18mm lens (it's around $600). My GH1 currently sports the 20mm pancake lens. Is there a adapter to attach to the 20mm lens? Or is there a lens that would be recommended for under $200?
 
From my reading, the 20mm is a bit weak to mount a wide-angle filter to it. Use the "stock 14-42mm" lens, and mount a wide angle to that. In normal daylight, you should get good results. Also you will have the benefit of image stabilizing for smoother shots.

I don't have the "stock 14-42mm".

If I was to by myself a new lens, as well as allow my brother to shoot wide-angle, would you suggest that I purchase the "stock 14-42mm" lens, and have my brother buy the adapter?

Or would you suggest another route?

How about the Samyang 8mm + M43 adapter? $225-260

Where did you get that setup for $225-260? Prices just for lens seem to be around $360. If that's the price ($360), then wouldn't it be better to get the "stock 14-42mm" and a wide-angle adapter?
 
The 14-42mm is probably a more useful lens. Even 14mm is pretty wide already. I have a $9 wide angle adapter which isn't too bad in this thread:

A wide angle adapter may not be as sharp at the edges and add some chromatic aberration depending on the lens.

The Samyang sells under different names like Rokinon, Bower, Vivitar etc. The price dips under $200 in some ebay auctions. Average is $250-260.

WA adapter is a most affordable solution. But the wider you go the worse is blurring, CA and smearing on frame borders, so it's better to keep frame composition centered.

kit lens on 14mm + .7 WA adapter ~= 20mm EFR
So your brother can get around 20mm EFR even with real 20mm pancake lens and 0.6-0.4 WA adapter.
 
The problem with using an adapter with the 20mm is that when the lens focuses the front (including the filter holder) moves in and out.
That means that if you're using an adapter - the internal focus motor is having to move many times the weight it was designed for.
This is true in either manual or automatic focus.

It might be fine - or it might bust your lens mechanism. I don't think anyone really knows.

I've not actually heard of anyone breaking their 20mm doing it but then most people probably aren't taking the risk.
 
The cheapest route to go would be the stock lens. You can get them cheap...sometimes under $100. The wide adaptors can range between $10-30 up to 100.
You will benefit from auto focus and lens stabilization as well. Action shots will need some quick movements and stable motion.
It's a decent everyday lens as well, which will fit most of your outdoor needs.

As long as you find the lens cheap, it's worth the investment.
 
I would get the 14mm F2.5. It is actually wider than the 14-42mm just because the lens is shorter. The Extra stop of aperture helps as well. Both lenses focus fast and are quiet. The 14mm F2.5 is ultra light though. It costs about twice what the 14-42mm costs. However, it is a better lens. You get what you pay for.

The in lens IS will not stabilize the types of movements that you experience while filming from a moving skateboard. Your best bet would be to remove the motion in post processing.
