Zoom magnifications HDR-CX450/CX455/CX485
When recording a movie with SteadyShot set to 60 timesWhen recording a movie with SteadyShot set to 59 timesWhen recording a movie or photo with SteadyShot set to or 30 timesWhen is set to 350 times Yes I think I've cracked it, it seems to be SteadyShot (Active and Intelligent Active) that is causing the pixelation with the cx450. when it's set to standard or off there is much less pixelation, though the zoom is much less. Actually doesn't seem like it's zooming in enough.Anyway thank you very much for your help. You can test this. Set the camera up on a tripod.Set it at a distance from a tape measure, of say 1m or 10m, running L->R. Have it at a distance so that the 1m or 10m just fills the frame at 1x. Then as, you zoom in, compare the captured length of the tape measure (Right minus Left cm values at the frame edges). This will give you the zoom ratio achieved.
Dan. CX450 is a Budget camcorder and that zoom range includes "digital" which should only be a last resort ( and done in EDIT !).If you restrict yr zoom to something nearer 20x ( using the tape-measure idea already posted), this should be perfectly good enough for getting the Story over.
To get a closer image, "Use your legs" is a good maxim, - except when you are on a train/ship/etc.
If you pay 10x this, then you get lots more features a bigger Sensor and the larger glass that implies ( which is where the costs escalate).
The cost of image quality is the main reason IMHO why 4K camcorders have such a poor Zoom range.... it's as though they expect you to "waste pixels" to zoom-in . . . which rather defeats the point of a 4K sensor.... although in HD-mode and shown on a large screen it's surprising what can be achieved.
A tripod is essential for any "Tests" so as to eliminate at least one variable... the Operator.
Cheers. thanks 12harry. I haven't been able to do the test as I don't currently have a tripod but i'm certain the CX450 does not zoom in as much as the CX115e. Even though it's supposed to have more optical zoom.
I've been thinking about buying this 4k camcorder https://www.amazon.co.uk/gp/product/B078XX5P8V/ref=ox_sc_act_title_1?smid=A3P5ROKL5A1OLE&psc=1
It apparently has the highest 4k zoom at 24x optical, but I wonder if quality is lost at full zoom. Its a Leica lens - what do you expect? The optical zoom is up to 24x but the intelligent zoom will take you to 32x or 48x without any loss of picture quality. Specs - DC-FZ82 LUMIX Camera | Bridge Camera Case | Panasonic UK & Ireland

Pretty good quality. Optical zoom "should" be the limit for quality image stakes... as any addition effects must lose pixels, even though the various "boosts" are retaining all those needed for HD ( hence the claims that image-quality remains ). However, fewer sensor pixs-per-pixel must introduce some additional noise ( or some downgrade)...otherwise they wouldn't use the sensor with all pixels presentThat's my take, FWIW.
Terfyn, that VX1 Pana looks like a further improvement for moving-making, as you will know - I like the Active Contrast and Dolly-Zoom features and whilst "more Zoom" would be nice, what it really lacks is a built-in ND filter - even ax4 would be better than having to remove the sunshade and then screw-in a filter.
- There is a Sony with this.... but it's a lot more money. . . and lacks some "Umph" -er, IMHO.
A 24x Zoom isn't too much of a downside... since it's way more than most SLRs ever had - and modern Bridge-Cameras are less convenient for movie-making; although they do offer long zooms and the Pana 2000 (DYOR) has ND filters - odd that, when in Stills-Mode you can have a short exposure.
Cheers
