Hello I'm Graham and I hope everyone's having a great day and welcome to
today's video Now this video is a continuation of the
yesterday's video in which we were talking about the zoom modes of the
panasonic lumix bridge cameras so well do a zoom the extended optical zoom and
the digital zoom and I hope you saw in that video that we could get some fairly
decent quality by using either the iPhone or the expanded optical zoom now
in today's video I want to look at the same features on the compact systems
cameras now they don't support the Eisley was that's a reserved for the
British camera but would they do support the extended optical and the digital
zoom now the extended optical zoom is Wanda
is likely to trip most people up and some people probably don't even
recognize that there is the extended optical zoom on these particular cameras
so I hope to demonstrate that today and the quality of the images that you can
actually get from this camera so for example here with the panasonic lumix g9
I've got the 12 to 32 lands on here but using the extended optical medium
setting in the 4k mode I can actually get 34 to 19 millimeters effective focal
length and if I was to shoot in 1080p mode that I can get 48 to 128 so you can
see I've got quite a variety of zoom lens just from the kit lens if you want
to consider longer focal length lenses like this Olympus 42 150 then in the
1080p mode I can get something like 600 millimeters effective focal length from
lens or just over 400 millimeters of her shooting in the 4k mode photo mode not
the video mode where we've got the extra time to 1.7 crop now to enable the
extended optical zoom we need to go into the record setup menu and would be
different with each of the cameras for the Sensex in the record setup menu and
you're looking for one called extended teleconverter now in the stills mode
you've got these three options they're off off teleconverter or zoom now if you
select the teleconverter it's a fixed times to zoom operation so your 24
millimeter lens becomes a 48 millimeter lens in the zoom setting it means you
can actually use the touchscreen to change the amount of zoo
from x 1 to x 1.4 so that's a more useful range you limiting the amount of
digital zoom you're applying to the image and you can get some cracking
results from these larger sensor cameras in the video mode you've only got the
option of the extended teleconverter so you using the x tooth setting to give
you a boost to your focal length when you shoot some video and you'll see some
of the results of that later in this video
now it depends on the camera as to the size of image you will get but if the
camera is 4k enabled so like the G 85 the G 9 you'll find that the extended
optical will actually coincide to a 4k setting of 3840 by 2160 or a 1920 by
1080 which are the equivalents of HD and UHD format so the actual scale to give
you perfect pictures within your video file now here on screen I'm going to
show you some images shot with the 40 to 150 lens on the G 9 in the stills mode
and first of all without any optical zoom applied so we're just using the
native sensor resolution and the large we've got the 14.5 in the medium we've
got the 4k sized and in the small we've got the 1920 by 1080 so these are the
native files from the camera now I'm going to switch over and show you what
happens when you enable the extended teleconverter option which applies the
times 2 now the images on screen now are with the extended end position and the
extended s position the first one gives you the 3840 by 2160 file so that's a 4k
file with a times 2 extension on there so 150 millimeter lens becomes
effectively 600 millimeters when you apply the times to micro four-thirds
crop and the times to extended M crop we can actually use the digital zoom on
these cameras to good effect as well unlike the a zoom on the bridge cameras
there's no additional processing in either these options so you're using
your own processor uses the photo styles or you
can actually post process these images to the way that you want to get your
final result so in the case of the digital zoom we can either select times
to or select times 4 and you can use this with the large format so you can
use this with a 14.5 megapixel image and again your x 2 or x 4 zoom to that or
you can use it with the end position or you can use it with the extender then
position and add digital zoom to that so you cannot get to get some super long
telephoto shots if you are preferred to suffer a little bit of image segregation
now a lot really depends on the use of your final file if you're going to be
using these images for printing then you want to use the zoom position where you
can control zoom up to times 1 point 4 and that gives you some superb images as
you seen on the screen if you're using them for webpages then you can actually
use the extended M plus these extended Telekom Burton to give you at times to
zoom or you can use digital zoom times to are times for to give you a
combination to get some super long 1600 millimeter shots if you wanted to but
again it depends on the size of the images you want to display on the web
page now if your consider shooting video the scene becomes a little bit more
complex for example with the gh3 you can't use the extended teleconverter
with a 50 p or 60 p frame rate it will only work with the 25 P rate so if
you're using it with the gh3 there is a workaround that and you can use instead
of the extended tella condition use the times to digital zoom and that gives you
the same effect and again you'll get some good results from that times to
digital with the 1920 by 1080 mode with the later cameras and the gh4 and above
you've got the option there to use the full frame rates even in 4k mode you can
shoot with the extended tele option or use x 2 or x 4 digital zoom depending
again on your output needs but you can get some superb video by using the
extended end position in 4k to give you an X
two times two on top of the times one point for crop of the 4k video mode so
there we are that's how to use the extended optical and the digital zoom on
your compact systems cameras now hope that's been useful if you renew viewer

share these videos that would be great and fantastic news for me so have a look
at my photographic blog there's lots more information on extended optical
zoom digital zoom rising for the bridge cameras under the photo stock page and
I'll put a link to that in the video description below and also on the home
page of the blog you'll find the application to join my newsletter group
now that goes out to over 2,600 people every three weeks and it's more than a
newsletter it's almost a technical publication and its own right and it's
