I just got this lens in and I think 'm in love. For an inexpensive lens it's tack sharp on the GH2.

Thats the fisheye lens correct? I think you are the first person heard of to buy that lens.

Yep the fisheye. I did a lot of research on it before I ordered it. Very good reviews.

The corners are good, it's sharp all the way open, focus is smooth, better than it should be in low light and I'm flattening the image now to see how that works out.

This is a picky bunch and they liked it,

I've got the Rokinon last year, same thing I think. I've had fun a couple of times with it, but I keep meaning to put it in the classifieds. Fun lens.

I wish I'd known that Jeff. I could have saved some money and you could have gotten rid of it.

This is a Jpeg frame grab. It's a little deceptive. The motorcycle is really directly to mt left.

Never been able to find a practical use for a fisheye lens. I'm sure they have there uses although they always seemed like more of an effect lens.

It's pretty easy to remove the fisheye and leave the ultra wide image.

This one's going to get a lot of indoor use in large rooms at the senate.

Just playing lat night to see how it does in very low light, this gives an idea of the 180 degree spread.

Don,
How do you do that?....I assume you would use the "lens correction" feature in Light Room or other software.

Premier Pro, Distortion, Horizontal ....Jeff

I'm getting kinda fond of this little lens. I just have to remember to keep my fingers out of the shot.

Got the Rokinon 7.5mm 3.5 for a recent project and was happy with result.
Great lens for GH2 but for very specific use.

how would you do that lens correction in Vegas Pro?

I agree Alex, it is specific but very useful to me. It has a 180 degree spread witch blends nicely with GoPro 170 degree. I use the Gopro's a lot.

Don, I had GoPro and loved it but image just wasn't cutting with my other cameras, sold it with regret.
Will be using this fisheye on stage next month and will report here.

I have also borrowed a Zenitar 16mm 2.8 fisheye from a friend of mine for some stage production and was happy with it. The angle of view wasn't so extreme and it looked more like a wide lens on my GH2, could compete with 12 mm, but focusing was a pain.

The IQ is getting better all the time Alex, and sometimes it's the only practical way to get a shot. The GP2's are way ahead of the 1's and they are coming out with an upgrade to bring the bitrate of the 2's to 35mb as well as a flatter profile and more.

Even the 1's are useful. I got this with a 1 tonight during a storm then had some fun assigning colors to the intensity of the flashes.

Don, I got out my lens to put it up for sale, and my Rokinon and it's 8mm instead of 7.5mm like yours.

How weird is that?

Anyway, anyone looking or interested I put mine up for sale in the classifieds here, along with an adapter for the GH2 included, for $225.

I'd think it would go fast Jeff. It certainly isn't a walking around lens, but I've found it extremely useful.

Just a heads up for those that bought or have a jib/crane....this lens is a showstopper on them.

Very Nice Jeff

Nice pics....
Did you use the GH2/7.5mm to shoot the RACE?...or just the folks?
Post more when you have time.

I don't like the race Jeff. They tie up traffic and bring in crime. I just video the people. Last year I got a fellow passing fake hundred dollar bills.

I wouldn't even be here except I had another event to video this morning.

Those are frame grabs from video BTW..

So Don...
Are you doing these events for fun or income. Fill us in.

For profit Jeff.
One of the reasons (Other than bandwidth) I don't put anything but test and occasionally insulting political things, online is because I try to shoot for a captive audience.

I contract for X number of DVD's from a client. In the case of the races, one of the sponsors. They have to purchase a minimum number of copies.

I do some news items, almost always an event, demonstration or something that I'm pretty sure will turn violent, and use it for broll or combined for another DVD or for the news syndicate my company has.

I'm the lobbyist for a rural affairs organization and video legislative goings on because I've found it's a very effective reminder of what the legislators said. They have convenient memories.

I'm a cranky old goat that would rather stay on my farm taking pictures of my bears unless someone pays me.

Yesterday I shot a picnic that was really a pre legislative session.get together for the largest gun lobby in the state. Eventually I'll put that with other events and sell the DVD's.

I've found it's all about playing to a target audience.

Yesterdays shoot was a long 15 hour day and I used the new AC 160 (Which I love) and two GH2's, one with the 7.5 for unusual shots. It works really well for that. Notice I said unusual rather than artistic.There isn't an artistic bone in my body...

@ DON...
Thanks for the info....I didnt mean to be nosey...just curious.
Great ideas. I need to do some of that, it sounds like interesting shooting.

Have a great Sunday..
