The 7-14 arrived, unfortunately I don't have the time today to get some sample footage. So take this selfie at 7mm f/2.8 for now. I do need to be careful, it does seem to distort a lot around the edges, I doubt faces will look good.

This discussion is where I'm having trouble too. 12mm isn't wide enough for my purposes and all the 10mm and under options are a big compromise for me. I really wish Panasonic would add an 11mm f/1.7 lens to their lineup. It would be a perfect fit with their other primes. 11, 15, 25, 42.5

F2.8 just doesn't work for me as you have to be very close to the subject to get shallow enough depth of field and then you get that distorted look at these wider angles.

Looking forward to seeing you samples with that 7-14 still though.

Cheers,
Pete

I think that lens is broken, unless your face looks like that :) 7mm is more for wide spaces, I think it's normal that it distorts like at it's widest and in a narrow space.

Noa I think the jpg correction is a bit weird. I know the pics look different when you compare RAW to jpg because the camera compensates for distortion.

So, alright, I filmed my first wedding with this lens yesterday. Here is a short clip chosen at random, straight from the camera:


Here are some thoughts:

1. The distortion is much more acceptable for video, even at 7mm. I was worried that it would be a problem but I doubt any client will mention it, unless I really get in their faces.

2. The lens suffers from a lot of flare, even from standard light bulbs. If you look closely you will see little spots of light across some people's faces. I'm not sure I like that.

3. The reception for this wedding was quite dark and I was struggling. The clip I uploaded is 1080/25p, filmed at 1/30 shutter speed and either ISO 2500 or 3200, not sure. Still, there is a considerable amount of noise and compared to your sample footage taken with the 42.5mm at the same ISO (Noa), mine just looks awful.

I was shooting in Natural:

* contrast -2
* sharpness +2
* noise reduction -5
* saturation -5
* luminance 0-255

Rest is stock. Am I doing something wrong here? Judging by our footage it looks like we have different cameras.

For those who haven't seen Noa's video, here it is:
(password: test)

EDIT: I looked at my own vid on youtube and it does look cleaner thanks to compression I guess, the original vid has a lot more grain to it. however, there is still a noticeable difference in quality between the two.

I shoot standard, everything at zero and 16-235 luminance, you have noise reduction at -5, does that not mean the camera is not applying any noise reduction at all which could explain your noise issue?

I doubt going from NR -5 to 0 would make the footage look like I didn't capture it in iso 3200 but rather something like 1600. The luminance thing... I will try it for my next wedding. Standard too. Thank you.

from my testing noise reduction is a mixed bag on the GH4. Sometimes it works great and others it makes the footage a tiny bit mushy. I've never seen it look significantly worse with NR at 0.

What recording mode were you in Luc ???

Shooting that original is 1080-25p would explain it. Shooting 4K UHD-25p and down scaling to 1080-25p output for youtube is radially better. Noise almost completely disappears when downscaling 4K to 1080 for me.

That 7-14mm definitely looks good and is a tempting piece of kit !!!

Cheers,
Pete

Re: New lens talk: Olympus 7-14mm 2.8, Olympus 8mm 1.8 and Voigtlander 10.5mm 0.95

I rarely shoot in 4k. Don't know why, but I don't like the feeling I get from that extra crop factor and the significantly slower autofocus, so I avoid 4k. I am also a big fan of slow motion (even 50%), so 25p doesn't really work for me. I film all my weddings in 50p unless there are low light issues where I have to use a slower shutter speed than 1/50. You never know when you need to slow-mo a clip to get something nicer out of it.

fyi, that particular coffee clip was shot in 4K and downscaled in a 1080p project in Edius.

Re: New lens talk: Olympus 7-14mm 2.8, Olympus 8mm 1.8 and Voigtlander 10.5mm 0.95

I did ask you that on the other thread but you didn't respond. So is that the solution then? Hm. On that note, forgive me for asking an even more off topic question, but do you guys recommend recording on a 128GB SD card? I did record a wedding in 4k just once, and I found myself running out of space exactly during the service at the church. with a 64GB card. 128 would solve the problem but I'm worried that if something does happen to it I will lose a big portion of the wedding. Thanks.

Re: New lens talk: Olympus 7-14mm 2.8, Olympus 8mm 1.8 and Voigtlander 10.5mm 0.95

Just keep the idea of shooting 4K and even down to 1/25th shutter in your bag of tricks for that super dark shot you have to get. I also like to shoot 1080-60p for most of my action shots so I can get good slow motion, but when I need to I'll shoot 4K and 1/30th shutter. It gives some great results when nothing else looks good.

I only shoot with 32gig cards. I never like having those super long clips in the first place. Then I am always protected on most of my footage in case a card goes bad. For your weddings, 64gigs should go for 80 minutes and be sufficient for the ceremony. If someone really needs the whole ceremony from start to finish, I'd use a 1080 camcorder for that and use the GH4 for all the beauty shots and the video that will be distributed. Only the bride and groom will ever watch the whole ceremony ever again. Most likely, not even them :)

Cheers,
Pete
