GH4 with motorized head

by itominski » Wed Feb 04, 2015 5:59 pm

Hi all,

Can I used the GH4 with http://www.kolor.com/store/panorama/har ... pixel.html this motorised head?

If so, do I need to do anything different?

Why do you wish to use a motorized head?

What sort of scenes do you wish to shoot and with what focal length lens(es)?

Hi,

I am looking mainly at virtual tours and thought it would be an easier-faster way of putting it all together.

Apart from this I was going to try some gigapixel pictures.

I have already purchased the head, it arrived today but didn't realise the GH4 wasn't supported.

For shooting virtual tours with (typically) a fisheye lens then a manual head will be easier and faster.

A motorised head comes into its own when shooting hi-res panos with long focal length lenses.

Does the GH4 support wired or infrared remote triggering of the shutter?

If so it can probably be made to work with Panogear/Panoshoot.

Hello "itominski" ...
normally the correct cable is delivered with the "Trigger cable package " of the Panogear !!!
If not... ask Kolor to deliver ...
Otherways , the cable you mention on Ebay will probably be OK ...
To play 100 % safe, you can buy one by following the next link :
http://magasin.skivr.com/en/accessoires-panogear/156-trigger-cable-for-remote-for-camera.html
of course choose the correct one (Panasonic !?!)

Thank you all for your input.

Can I ask for hi-res panos with long focal length lenses what type of lens should I look to purchase? I currently only have a Olympus M.Zuiko Digital ED 12mm F2.0 Black lens for my GH4.

Thank you for your help!

It all depends on what resolution you feel you want/need in the final pano.

If you download the Papywizard software and run it in simulation mode you can get an estimate of the res. of the final pano for different focal length and pano fields of view - see screenshots below.
http://www.papywizard.org/wiki/Download (choose the development version)

I tend to feel that 75mm (35mm equiv) and up is what I'd term 'long' for shooting panos; by which I mean I'd prefer to shoot with a motorised head rather than a manual head if only (but not only) because of the number of images involved.

So with your sensor crop factor of 2x then you'd be looking at say 35-40mm and up.

Really long lenses such as 200mm and up (35mm equiv) start posing much greater challenges in terms of shooting conditions, shooting time and subsequent processing. The shooting phase is typically not the most challenging aspect of creating hi-res panos.

I'd suggest you start with something like 100mm (35mm equiv) to make a start, or possibly start with something longer but shoot at lower res. to make the processing phase more tolerable whilst learning.

Thanks so much for that info. Do you have an recommendation on actual lens to purchase. I did fancy the OLYMPUS 75MM F/1.8 but I guess that I would be better off with Panasonic Lumix G Vario 14-140mm for all round usability especially when considering my only other lens is the Olympus M.Zuiko Digital ED 12mm F2.0

You will need to shoot in manual focus mode, otherwise many cameras refuse to trigger the shutter if autofoucs fails to achieve a focus lock, and this is common when shooting scenes with a lot of clear sky with a long lens.

So check that any long zoom handles OK with manual focus. Also note that some zooms may suffer zoom creep and/or focus creep as the lens/camera is pitched up and down on a motorised head.
............
The longest focal length I've used to date with my Merlin mount is 50mm on a Nikon DX sensor body - so 75mm (35mm equiv.). I used this mostly because the Nikon 50mm f1.8 prime is a relatively low cost but high quality lens which exhibits minimal distortion. The images stitched very well. This was for hi(ish)-res interior partial or spherical panos rather than distant landscapes.

Thank you so much for all that info.

Would anyone have actual model number combinations for the GH4 that they would recommend? I think it is going to need to be a zoom lens and probably might as well be Panasonic due to the IS.

I Agree with Andrew , its better to use a manual focus not to long focal
exemples:
http://www.photozone.de/olympus--four-thirds-lens-tests/704-oly45
This is one of the best lens for Micro 4/3 But a little bit long = 90 mm

The next one but full manual could be
http://www.bhphotovideo.com/c/product/859178-REG/Samyang_SY35M_O_35mm_f_1_4_Wide_Angle_US.html
A full-manual lens is a excellent choice for panography.
I use personally this Samyang 35 mm ( and the 85 mm too) on a Full frame Canon 5DII with beautyfull results really !

But I repeat FULL MANUAL (for lanscape, architecture and Panography)

Is it recommended to use IS when the camera is mounted on a tripod?

I cannot suggest specific lenses as I have no experience with micro four thirds systems.

Do you think the OLYMPUS 75MM F/1.8 would provide good results or do you think the focal length is not long enough to achieve this?

The OLYMPUS 75MM F/1.8 is a "excellent objective" BUT the resulting focal on a Micro 4/3 will give 150 mm eqivalent ....
and for Full pano this is "more then probably" a too long focal and you will need "too much pictures" to achieve a correct result ...

I suggest that you first try to use your existing material for some pano trial's, then decide wich focal is the best.
In the beginning of the present post, you speak about "virtual tours" and for that you don't need very long focals...
Before deciding to buy more material, try to find a friend who can give you atrial with a more long focal for a trial .

Thank you for your response. That is exactly what I have done. I guess I am just too keep to put the motorized head to work and play with a new lens as I only have the Olympus M.Zuiko Digital ED 12mm F2.0 for my multirotor.

Thanks for your help again.

Guys can anyone give me some guidance in getting the papywizard to work with the wifi module provided in the panogear set. I can't get them to link. Or if this is not the right way to link them what is?

Thanks

Papywizard won't work with the Panoshoot wifi 'thing'.

You'd need a Bluetooth-TTL interface module for the Merlin/Panogear head and a Bluetooth capable platform to run the Papywizard software.

You can get a Bluetooth-TTL interface module from here:
http://www.papymerlin.com/interface-%C3%A9lectronique/
Or here:

Thank you for your super fast reply, I have wasted hours on this trying to get it working.

Why do they provide you with the wifi then? I take it Papyawizard is better than the Panoshoot as that looks a little limited.

However it should still do what I want but when I give it a simple 360 it doesn't perform it!

I'll order the bluetooth dongle but for now all I wanted it to do was soot a basic Spherical for virtual tour.

From what little I know about the Panoshoot I believe the WiFi is to connect to a PC or a tablet or a smartphone.
