| Questions about WW for NV-GS 250 / 400, XM-2
Question of rtzbild:
August 2005
Hi All,
I am currently working with a Canon MVX30i, it is small, practical, unobtrusive, and you have them always with you.
The pictures in and out of a light aircraft were good, the Optical Image Stabilization (OIS) is great, the low-light capabilities sufficient.
Now it attracts me because of body size and stature, o))
I ausgeguckt me:
Pana NV-GS 400
Pana NV-GS 250
Canon XM 2
Question:
How is the wide angle of each model in mm KB?
Unfortunately I have not found anything about this in slashcam.de, digitalvideoschnitt.de or the manufacturer sites.
Thanks, Olli

Hello Olli,
unfortunately it is not so easy, therefore, the MF range is usually mentioned only in test stores. This means that you have to take the action the sensor size,
with 1 / 2, 5 "(Have the Most Fotocamere's with 5 million pixels) white ichs then in the head by 6, ie the first number in front s.Lens times 6 you have the focal of KB, then there are lists in which what the BW WW.
Unfortunately, I have to work, perhaps someone here knows. Good one Videocam with 1 / 2, 5 "gibts in de lower price ranges because even LowLight Primus XV 2100 1 / 3" has (Well 3 of them) or semi-unit Canon XL 2 Entry-level model Pana GS 17 has eg 45 degrees without a good converter.
But that means if you know this the same sensor in the Cam's work, which is the smallest Cam with 1 count on the lens, the Cam with the best WW (PS: The light intensity or Aperture on it, of course, is synonymous with 1:1 , 2 zb)
If there are no other replies I sign up again.

So I can show you the following:
XM2 normal without on Lenses:
for image
XL2 with Wide Angle "Canon WD-58H"
for image
XM2 with fisheye "Raynox DCR-FE180PRO"
for image
One point to note would be the following: The Canon wide-angle lens is fully zoomed. The Raynox Fisheye is the heranzomm s.ca. 6x Zoom s.den edges blurred.
Here x 5 images that show the appearance at different zoom levels. (The last picture shows the maximum s.Zoom what is possible with the Raynox Fisheye)

Hello you,
My little list I found, but rather for digicam's true but it is synonymous to Videocam's conversion.
Format_KB24x36mm_APSC15, 7x23, 5_4/3_2/3_1/1, 8_1 / 2,5 _1 / 2,7
Diagonale_43mm______28mm_____21, 5_11, 4_8, 6__7, 2__6, 4effektiv_ca

23_________105mm_______68____52, 5__28___21____18____16
18_________135mm_______88____67____36___27____22, 5__20
The angle of view: For the half Bidwinkel ß / 2 is tan (ß / 2) = Focal/Bilddiagonale/2.
p = 2 (inv tan (Focal/Bilddiagonale/2)) Either you can work the real focal and effectively utilized CCD using diagonal or with the Small comparable values.
Focal comparable KB
Knowing the effective diagonal (y) and the real focal (f) estimates that one f / y = KB / 43mm, this is 43 mm for the diagonal of the film's KB and KB for the desired focal length Small: KB = f / yx 43mm
Brennweitenfaktor = 43mm / CCD diagonal
I hope I have not scared you zusehr, this one must have probably studied mathematics ...

Hello Jan, thank you, for your erstmal mathematics, but unfortunately I am a very lousy Calculator, I'll tell you though, is how much a picture with 18mm KB and how much is left over 200mm with KB, but I do have difficulty with simple fractures ... : o (
I say stop 14/18/...45 mm KB something because I can do what with, but everything else xf (Chip Size / s etc) is too high.
But thanks.
Love Greetings

Hello Jan, _sowas_ helps me even more because I can see a system that maybe the time I transfer to a Exell table.
But first I Bookmarke me the times o)
BTW: For me, the table subber, perhaps liecht s.der system font, non-proportional set?

Hello Hogar,
You make an effort with me, yes you, omajusepitter ... o)
Thank you!
As I see produced, the XM2 in WW-position no cushion or barrel, it stands out.
The okinal-WW-Converter Canon WD-58H of noticeable but not dramatic tonnes, with a Fisheye has failed in one of the edges parallel WW ever.
You had me at the same time given a buy tip for the Full Resolution Sample of you is also shown that what is often spatially allowed us press people ...
Meanwhile, I'm ready:
XM-2 of Media Online for 1903.00
a Philips SBC ME 570 for 10-20 Eu's
a UV glass of B & W
And lots of Batteries www.sell-way.de (ebay'er)
And then just the WD-58H.
BTW: I still have the okinal Olympus WCON-08B of the E-10, who has his caliber 62mm, but would have to with 'nem compensation ring to create?

Hello,
I have only synonymous GCSE, the table is one of Stillimage magazines, but very interesting times.
In Videocam's not used quite as optimally dei CCD barely mentioned, except in Profibreich.Bekannte CCD sizes
are 1 / 6 (beginners), 1 / 5, 5 or 1 / 4, 5 middle about 600 ¬ or 1 / 3 for demanding XM 2, VX 2100, XL 2 I think you can put it into proportion. Zb case it is an Videocam with 1 / 2, 5 "CCD
Lens on one 7,3-73 (eg 10x zoom is now) white
I, the cam has a focal of 43 mm and the Wide Anglevon 53 °. Unfortunately, one must always put the chip size in relationship, except there is a cam with 24x36mm format CCD, Could well be very expensive?

Hello Jan,
the "problem" chip size, we have discussed several years ago on the Usenet, just before as the Olympus E-10 came out, actually the first Digi-SLR with decent WW.
The chips have all pixel errors, let's say 1%.
A chip can only be accepted for any DIN 3% have defective pixels, ie, at 300 pixels only 3 dummies.
Now, however, pixel errors occur more frequently than is dear to the Manufacturer. And the larger the chip, the greater the probability that the things wrong and therefore the Committee.
And the higher the rejection rate, the higher the price of the remaining, so serviceable chips.
And therefore we have to wait a while before my F4s or the Rollei is provided with a frame-filling digital back without Focal length: o))

Hello,
I thought for a video camera. In Digital's gibts zb already Vollformatchip cameras. Canon EOS 1Ds Mark II with CMOS 24x36mm scarce 8000 ¬. In the old model's is not cheap as synonymous with the good F4, wait times whether what is coming. For the noble Leica R9 has been so recent a back wall with CCD 26.4 x17, 6mm, funny only costs them ¬ 4500 - more than the camera.

Hello Jan, hello forum,
I found there was:
Under www.mediaonline.de the focal length (KB) are indicated with.
