You're believing the marketing department too much. These Schneider Kreutznach lenses were originally made for the Super-8 format, and a Super-8 frame is much more like an HDV chip than a DV chip. At 4.1 x 5.4 mm, it's also considerably bigger.

I have recently changed over from a VX2000 to a Z1. If I film with them both in the standard definition mode, I can tell you that the VX2k gives better picture quality. The Z1 has a 'Hi-Def' lens OK, but the camera itself is only backwards compatible for good solid marketing reasons.

So don't worry that Schneider made lo-def and hi-def versions of the UWII - they didn't. The injection moulding tools were very expensive to produce with their complex aspheric surface, and there's no point in 'degrading' that because it doesn't make any of the lenses any cheaper.


Nothing wrong with your English Prech.

Looking for Canon Wide Angle Lens Hood...sigh...
 

So annoyed, I just about a WD58H lens off an Amazon seller, and despite the H, it shipped without the tulip lens hood. I'm waiting to hear back from him now, but I'm also looking online and having trouble finding anyone who sells it. I called Canon, and they have the part for $20 + shipping + tax...So I figure I must be able to buy it cheaper online. But I don't know much about lens hoods.

The part number from Canon is D52-0210-000.

Thanks!

Also, when the zoom is at full wide angle, I see rounded lines on the sides. I read that most people could use the full zoom with the lens in. Is this normal?

Best bet is to buy from Canon since they are the ones who make it. $20 is cheap compared to the $52 it cost me for a replacement lens hood on the 16X manual.

You likely won't find it anywhere else online.

Thanks
 

Thanks for the advice. $52??? That's highway robbery!

It's highway robbery only if you don't actually receive the item. Otherwise it's known as charging what the market will bear... which is a very common thing in this industry. $20 is a bargain.

White balance blue with Canon wide angle GL2
 

It seems my white balance is a bit blue when I am using the Canon Wideangle lens.

I use the auto setting.
When I remove the wide angle lens, the white balance seems good.

Anyone else notice this?

How are you testing this? The WD will also reduce light levels, maybe this is what you are seeing too? It is a big piece of glass.

I can tell by the viewfinder and the resultant image on the screen.

I am new to DV cameras, but have used 35mm for years.
I agree that the lens might reduce the light available, but why would this shift the color on the white balance?

I understand. So you haven't put this through any Test & Measurement [T&M] software?


- I've only been with DV for 4 years. No 35mm experience here - so you have the "jump" on me in that dept!


- Well it does. Not a lot, but it is noticeable on the EXPOSURE scale. I got about 0.25 DOWN of one of the exposure "notches". That is a quarter OF a quarter!

Well, maybe what you see on the screen is sensitive to the light levels and the actual LCD is reacting to that. See? The less light, the MORE of the BLUE spectrum you would see - yeah?

But anyway, I was making conjecture. What I really wanted to do was set up a T&M session.

OK, I just spent an interesting hour setting up HAMLET T&M software using my XM2 as the device and sent a signal WITH and WITHOUT the wide-angle.

In a controlled, artificially light environment I white balanced. I used my Pro White Cards for white balancing and executed the correct white balance procedure. White balanced locked and stayed locked.

Exposure was kept to the optimum setting of F4.4. All settings were MANUAL.

Using the RGB Parade manifest of HAMLET T&M, the results indicate that there is no "apparent" difference from WIDE to non-WIDE angle. Each of the Red, Green and Blue wave forms have the similar distribution - both "visually ( ie LOOKING at the curves weight and density!) AND the scalar values.

As it happens I DO have an opportunity to visit HAMLET very soon, and as I have "printed-off" a colour copy of the screens, I shall be quizzing the professional T&M specialist on our behalf.

Interesting, if only to have got me off my bum and do some empirical testing for once!

Grazie

when i attach a wd58h the whitebalance doesn't change.

The WD58 glass should be color neutral for normal light sources.

Auto white balance is based on the overall image content. When we attached a wide angle the field of view is much greater, and perhaps the color balance of the wider image is different than the narrower image due to different colors at the edges of the wider image. This can fool the auto white balance to giving a different setting.

Try usng manual WB, and zoom in to the same field of view when setting white balance, then zoom out.

I recently purchased a wide angle adaptor for my Sony Handicam .. and liked it so much that I decided to get the Cannon adaptor for my GL2. Best news is that B&H Photo had a used one including shade (rated +9) so I snapped it up and saved around $50.00! :-))

Just received it today and have only mounted it on the camera. BOY is it impressive looking. I'm glad to have it in my "arsenal" of accessories for my GL2

Back in the "old days" I remember purchasing inexpensive lenses for my 35mm still camera (inexpensive = not the same brand name as the camera).

I *do* remember that there was a distinct color shift over the stock lens. It was only when I shot slides since the printing process of negatives would often compensate for slight shifts.

I'm not saying that this is the case now, but it is possible to have a color shift even though you can't notice anything when looking thru the lens with your bare eye.
