Was subjected to a friends home video, yesterday. Admittedly on a 55” curved mega screen, but the video quality was quite outstanding!
I fondled the camera and was amazed at the quality of the viewfinder. Much brighter and more accurate colour rendition than the Fuji electronic viewfinder. The wife fell in love with it!!!

:8-)

I hadn't really thought too much about bridge cameras and their role in the grand scheme of ....video. But apart from the excellent viewfinder and results it occurred to me they have two very relevant advantages when it comes to video.

Firstly (it's amazing how the obvious can be missed) the absence of the pentaprism/mirror means you can see the videoing through the viewfinder.
One of my big critiques of DSLR video, is the need to hold the camera at arms length to view the action on the rear screen. It's not stable when handheld, on most bodies the fixed screen constrains viewing angle and is not ideal in strong sunlight. Being able to hold the camera up to the eye is far more stable and familiar. Yes I know a tripod is a part solution.

Secondly....motorised zoom. Whilst it's not good practise to zoom while filming (perhaps occasionally if combined with a pan) having the facility motorised is far better than trying to do it manually from the zoom ring of a DSLR lens.

The wife has a Panasonic camcorder...a high end one. But she has been less than happy with the stills she gets from it...so much so, she always wants to use my DSLR for stills.

She has flirted with the Fuji for the stills and a few videos. But the lack of motorised zoom and the revelation of how good a digital viewfinder can be, has probably put a nail in the Fuji coffin....for her at least.

So the Panasonic was very good.....anyone got a comparison or opinion on other makes?

The Fuji and Panasonic bridge cameras are very good for holiday pictures and especially video.
The sensor is a bit small for large enlargements unless it is bright sunshine.

If it works, use it!

As long as the camera has an external mic jack the motor noise from the motorized zoom is no problem.

Thanks for that, Mike. I will ask the owner if he has any zoom shots in quiet surroundings to see how much of an issue that may be.

This specific model has a 1" cmos sensor...are they others smaller?

Which model is it?

Snagged this chart a while ago on sensor sizes.

Hmmm!

I find their terminology misleading. They call this models sensor a 1".....yet it's dimensions are 13.5mm x 18mm according to more detailed specs...which is a four thirds according to that chart.

o.O

How can 13.5 mm x 18mm be 1"?

1" sized sensors are the new large but small sensors.
The Nikon1 series of cameras uses them.
1" is smaller than 4/3 sized sensor.

The sensor sizing in the bridge and compact camwras is confusing as the size is about what the lens image circle covers!

And yet the chart that Mike posted includes the description of the Panasonic 1” sensor being the same as 4/3.

Rounding up the diagonal length (22.5mm) to the nearest 5mm ? :cheersduo:

Found a better chart of sizes.:-)

Well thought out Peter...forgot diagonals.

Optical format is a hypothetical measurement approximately 50% larger than the true diagonal size of a solid-state photo sensor. The use of the optical format means that a lens used with a particular size sensor will have approximately the same angle of view as if it were to be used with an equivalent-sized video camera tube where the actual sensitive target is smaller than the overall size.

The optical format is approximately the diagonal length of the sensor multiplied by approximately 3/2. The result is expressed in inches and is usually (but not always) rounded to a convenient fraction. For instance, a 6.4x4.8 mm sensor has a diagonal of 8.0 mm and therefore an optical format of 8.0*3/2 = 12 mm, which is expressed as the convenient 1/2 inch in imperial units. The reason why it is expressed in inches is historical, dating back to the early days of television. The TV tube produced a circular image, but only part of that image was usable. The optical format is the diameter of the circular image for which the stated rectangle in millimeters can be used, and the circular image is wider than the diagonal by a factor of about 1.5. Wikipedia

For larger systems the size is usually given as the true rectangular dimensions of the imaging sensor in millimeters, such as 36 x 24 mm in the case of 35 mm film sized sensors.:bowing:
