Hello,
yes it is really unusual, 3-chip cameras generally have poorer wide, we now look at the Panasonic DVX 100 with fabulous 32,5 mm assumed. At least in the consumer class. The well-known VX 2100 / PD 170 is synonymous only 43 mm focal.
You can see the models with smaller sensors (1 / 6 ") are 35.7 mm (Panasonic GS 27 / 60) - 36 mm SonyHC 37, ok there are exceptions, such as synonymous as the Canon MD 110 50 mm focal in 4 / 3.
The majority of the 3 CCD Panasonics have very mixed focal lengths (47.46 and 45 mm - GS 180-500).
We can probably talk her out and I'm sure many users will have a different opinion as me.
I think the sensor still plays a big role, with small 1 / 6 "CCDs in the camera, the lens forward enough space to weitwinklig to be synonymous So enough from the edge light onto the sensor zuwerfen.
CCD's and CMOS sensors are just happy to stop synonymous vertically interspersed light (telecentric).
Yes it is synonymous to the zooming factor, the type of lenses used. The companies use synonymous provides the opportunity for her to model with the matching key data (body size, sensor size, how much optical zoom) with a matching lace Gesammtpaket that in matters of cost and benefit is best for them.
There are, however, synonymous structurally different internal structures - for example, in the distance setting, depending on how many lenses where the lens of an engine are pushed, the camera an optical stabilizer system, lens couples are moving, that you have probably observed.
We notice but HVD & AVCHD - except now Canon - synonymous probably because of the large 1 / 2, 7 "CCDs - which the company more trouble, at least be roughly divided into the 35 mm direction.
Wen you look at the HV 10 screen sizes, you could always think about - where are the lenses purely because there is so little space and then the large sensor?
Yes, the HV 20 has the same inside synonymous Lens 43 mm - in the transverse length of the camera, it would actually have been possible.
The companies are really fundamentally different, Panasonic GS 27 35.7 mm (4 / 3) and Canon MD 110 50 mm (4 / 3) - the same size sensor &.
So I think it's possible more Wide Angleeinzusetzen, the companies take for them but the most practical (cheapest) solution.
The high-resolution models use longer lines (1080), so is a pair of high-quality line of Powerful converter utility. Sonykennzeichnet it with Y, one should in any case a high-grade / multi-coated lenses to use.
For HDV / AVCHD times now you see any "crumbs". Companies often use the best lenses synonymous forward as a front lens, a plastic Converter bombers would destroy everything, and now times no preference whether he durchzoombar or not, recorded or produced great shading.

Hello,
Good explanations, but I do not understand something ... (I'm not a video specialist, brings the photograph of her).
Why is it not possible s.Consumerkameras (I know there are exceptions expensive) to install a removable lens.
It's easy but in all SLRs?
It would indeed not synonymous Choice s.Wechselobjektiven these, only one WEITWINKELOBJETIV?
Why does it not with the video cameras?
Thank you for a Antowort.
Antwort von paulpope:
Is there anyway on video cameras in the professional and aspiring professionals. All a question of cost.
Wide-angle lenses, the high art of lens manufacturing dar. And especially a zoom lens, from wide-angle to the telephoto range with no distortion and CA will cost nearly perfect just a pig and the money is in consumer cameras is simply not there.
But they exist in the professional field (eg Fujinonobjektive exclusives)
Antwort von paulpope:
Hello in the round!
what happened to me in the discussion to a larger area weitwinkel off, is the wonder of the bent edges and distortions.
How to cope with it, is that for you no problem if houses like mushrooms come along?
For this reason I rarely extreme movies weitwinkel.

Antwort von Bernd E.:
Why is it not possible s.Consumerkameras (I know there are expensive exceptions) an interchangeable lens to be? Technically feasible, of course, but the manufacturer would like with their devices very much like to earn money. And worth it because now even the much higher design and manufacturing costs for optical switching is not because of the higher price due then more customers would verschrecken. The best example here in the forum: On a question on changing optics are estimated at 50 for the cheapest Camcorders ...

Antwort von paulpope:
There are two types of wide-angle lenses: relatively inexpensive with fish-eye pattern, these are synonymous with minimal effort yet s.Rand sharp that bend the lines but more or less expensive alternatives and with incomparably higher optical expenses, which the lines do not distort s.Rand . With Nikon cameras KB has Lenses for example, two each with 15 mm focal given. This one was a cheap fish eye and the other a classic, accurate imaging WW. Price difference is about 1:6
The WW-Converter Raynox of 0.3 is an example of a cheap sharp, but distorting variant, which is quite interesting to effects can lead to.
Antwort von HV 20:
Had me on the Canon roadshow yesterday viewed the HV20. In Bad Light is the area through the new CMOS sensor Super. DC synonymous my Raynox HD-5050 Pro tried it. Losses low sharpness, contrast, super. Am fully satisfied and will be available when using this combination.

Antwort von Jan:
Yes today was synonymous to the roadshow - in Munich.
And did my HV 20 times more synonymous explained and viewed and played.
Although it started off funny - "HDV with are Canon, JVC, Panasonic and Sony - Panasonic is AVCHD and DVC PRO HD is, but certainly not with HDV - the question of the mere Wide Angled HV 10 / 20 could not synonymous be answered, but I had already guessed. The Building & Grounds costs were raised.
Now for the Pros score of HV 20 - manual Tonaussteuerung I found nice, although both channels together, but yes, we had suspected.
Schön Level with 3 colors - so that everyone knows where he resides grade.
The HV 20 has a built Graufilter, but the only car at high aperture values or high brightness zuschaltet occurrences.
The HDV Cinema 25 P - 13 parameters are fixed, very similar to that of the XH A 1 - only manual. The shutter speed can be chosen freely Cinema, nothing with a 1 / 25 seconds, we are many companies nacheffen.
A very amazing picture in the cinema mode with 1 / 50 sec, it resembles a 1 / 25 sec picture, it melt the frames have any trouble, look was a little softer and lighter, less contrast. Canon speaks of real frames, not zusammengemanschte fields, the new CMOS chip is to be responsible, among others.
The new CMOS was like the Canon SLR Rafinessen known refined. Each pixel diode now has a micro lens, with an even better light output is realized. Unfortunately, I had no Lowlight, of her feeling, however, was already a better snooze photograph
than the critical HV 10 to see.
Unfortunately I have the sharpness of error rediscovered s.Ende it comes to wearing the zoom, which means the AF camera pumping short times and knows at the moment is not exactly what they should do so would have to be 7-8x. This occurs only on very bright surfaces and lighting - were determined distance over 10 meters - too close, I was not. A similar error had the synonymous HV 10 - just as you would read in some forums had.
AF is very fast, especially of food on long distance (1 m a person then the person goes away - infinity), AF reacted quickly, even faster than some Sony - and these are the best in the area!
Menu, known as the shutter speed code, prefix aperture. Using the + - scale is synonymous the Aperture open & close it not only knows exactly where it is like with the manual shutter to work together.
Wide-converter is the new WD H 43 - a hot part, only for the model built, that there are good lenses installed, remember you have s.Gewicht.
X factor is 0.7, so that the cam get a usable WW.
The converter is not exactly small, it is said Canon would bring out all s.Qualität, which is synonymous certainly not be cheap, na mal schauen.
Battery is now BP 2 L 13, it can be synonymous to the NB 2 LH of the SLR 350 / 400 D or the Powershot G 7 are used, what Canon is expected to enjoy friends.
The CMOS creates really 1920x1080 True HD is supported by the HDV 2 Specifications then 1440x1080 abgeregelt, noise reduction is already incorporated in the CMOS, an Other "werkelt" later on this.
According to Canon documentation synonymous Sony XD CAM HD CAM and work with 1440x1080, I was a little surprised.
The Canon AVCHD Camera one until Christmas rausbringt is considered bomb-proof, I think you can in the Canon documentation hardly the H.264 codec as AVCHD & praise without actually such a camera in the range to have .....

Antwort von Jan:
I got me again thought about the Canon HV 10 & 20
Why has such a good daylight picture, what is in focus in the classroom is not to beat?
I believe that Canon deliberately almost 50 mm (just under 44 mm) focal used in a very good sharpness Wide Anglewäre the power not to create, because much more light from an even larger angle to the pixel would have to take what is lost again . List & do the shading Wide Angleauch more, Canon wanted unlikely experiments.
An almost 50 has a larger subjective synonymous sharpening impression of synonymous Focal - just like our eye.
What could be tuned ....
