Ultra wide low light option for GH4

Irfan — Mon, 31 Oct 2016 10:54:19 +0000

Hi there Im looking to get lens for shooting underground parties. I already own Lumix 12-35 2.8 and 20mm f1.7. Still Im not satisfied with them in low light. I would love something that is wider (7mm) and faster for gigs shooting. Fixed lenses with manual aperture and focus are not problem to me. But Im opened to any solution. Thanks!

Which CCTV lens for wide angle fisheye use ?

TruHype — Fri, 26 Jul 2013 05:31:26 +0000

Hello everyone,

I've recently started to get interested in C mount (CCTV) lens, for they are fast, wide, and cheap. So I wondered, is there any CCTV lens that I could use as a Fisheye (and get the same effect as the Panasonic 8mm f3.5, but faster) ? Here's a few lens I've found looking on the internet :

Rainbow 3.5mm 1.6
Tamron 4-12mm 1.2
Pentax 6mm 1.2 (+ wide conversion lens x0.45)

Wanted effect :

The GH2 exact m4/3 sensor crop is x1.86.

So I would like to get the same widness as the Panasonic 8mm or any 8mm Fisheye (Samyang, Peleng, Rokinon...) :

Panasonic 8mm : 8 x 1.86 = 14.88mm equivalent (no need for ETC mode)

Rainbow 3.5mm : 3.5 x 1.86 = 6.51 -> 6.51 x 2 = 13mm equivalent

Pentax 6mm : 6 x 1.86 = 11.16 -> 11.6 x 2 = 23.2mm equivalent -> 23.2 x 0.45 = 10.44mm equivalent

x 1.86 : GH2 Sensor Crop

x 2 : ETC tele conversion mode crop (to cover vignetting)

x 0.45 : Wide convversion lens

Does that mean we could use any CCTV c mount lens instead of the Panasonic lens to get the wide fisheye effect ?

A few videos :

Lenses :

C mount lens (1/2") work well on the GH2, but I heard that the CS mount lens (1/3") would still have really heavy vignetting because even with the ETC mode it would not cover entirely the GH2 sensor. Is that true ?

Interesting CS mount lens, but 1/3 inch : http://www.ebay.fr/itm/TAMRON-Manual-Iris-CCTV-Lens-3-0-8mm-1-1-0-ASPHERICAL-C-Mount-3-Mega-Pixel-/261248954560?pt=UK_CCTV&hash=item3cd3a6b0c0

I would use the fisheye to film Skateboarding.

Thank you.

Wide Angle converter for 14-140mm lens ?

TruHype — Thu, 25 Jul 2013 20:11:47 +0000

Hi,

I was wondering if any wide conversion lens could fit on the 14-140mm panasonic lens, like the "Wide Conversion Lens DMW-GWC1" works on the Panasonic 14mm f2.5 ? The thread is 62mm, so would some converters like this work ? http://www.ebay.fr/itm/Impact-DVP-WA65-62-62mm-Wide-Angle-Converter-Lens-/110823536775?pt=Camera_Lenses&hash=item19cd98f887 or http://www.amazon.fr/Olympus-WCON-Convertisseur-grand-angle/dp/B0000511RI

Thanks for answering.

Wide-angle Rectilinear Lenses

kronstadt — Tue, 19 Jun 2012 17:43:31 +0000

Hi all,

I wanted to ask if Panasonic Lumix G 14mm lens is rectilinear? and if Panasonic 7-14mm lens is rectilinear throughout?

And which other rectilinear wide-angle and ultra-wide lenses would you recommend for GH13? Please also mention the rough price for each lens.

I'm especially interested in legacy lenses that could be had for cheap.

Many thanks!

Sigma 8-16mm F4.5-5.6 on GH2 or Gh1

kronstadt — Wed, 16 Jan 2013 22:35:15 +0000

I'm considering getting a Sigma 8-16mm F4.5-5.6 lens for my Gh1 because is said to be a rectilinear (non-fisheye) lens. It is made for crop sensor APS-C cameras, but I'm not sure if it will work on m43 mount. Also, not sure if focus will work manually on GH2 or GH1? Any advice?

Has anyone tried this on a GH2 or GH1?
