Wide angle reality check

[timbook2]

love this thread! The extreme wide angle request seems to stem from the crop factor and I understand its reason. I am also sure there will be many more native 4/3 lenses in the future. I am really curious to see the difference of primes vs nikon or canon glass for example. I bet some of the 50mm and above lenses for photography are not going to be so much worse then the primes.

Fast and small and will work with AF100.

now that looks pretty awesome

[QUOTE=dop16mm;2139306]I think it is rather humorous that over the last while everyone has been clamoring for telephoto shallow focus solutions for video cameras, and as soon as someone builds one, everyone starts complaining about lack of wide angle. Compared to what? Yes there are super wide lenses for full frame stills for shooting big group interiors, but guess what we are movie shooters and can move the frame to take in the shot.

I think the real bennefits of wide angle lens are the near far relationships they create and the resulting visual dynamics. Moving your camera back to see more reduces those bennefits. There certainly are times when you simply need to get a wider view, but I generally am using a wide angle lens because of how it allows me to compose an image, not simply because it allows me to see more.

[svecher]

That would solve the problem

Great, then hurry up and buy this lens.



It's f/2.8 at the wide end (12 mm).

Want to trade 2 mm of width for F/2 aperture ? Go for it




Problem solved?

Do you think George Lucas was saying. "what's the crop factor" when he used the CineAlta camera to shoot Star Wars? The F900 is 2/3" sensor!

[Julienmassie]

Probably not
He paid some people to think about that.

And im not going to shoot star wars, i just need '' these dam ultra wide shot that dont fit and that are not used in featured film '' for my gangsta rap videoclip and a couple of specific job.


If Georges Lucas was about to film the next lil wayne videoclip on a AF100 he would pay some people to think about it ... again ...

So in this case i really need to think about the crop factor since i need a lens to do this type of job in my bag.


Svecher they say that ...

'' autofocusing system and covers a zoom range equivalent to 24 to 120 mm on a 35 mm camera lens ''

At 11mm I definitely get this, and for visual effects work it is a NIGHTMARE.

Why is it a nightmare? I have done plenty of 3D tracking and FX shots including comping 3D model stuff on my 10mm sigma plus 7D no problem. Maybe your probelm is you didn't remove lens distortion first? Or you're only doing 2D tracking/FX?

So in this case i really need to think about the crop factor.

But how wide do you think you'll need to go? 7mm (from the 7-14) on an AF100 is as wide as 13mm on a "full frame" camera. Neither Canon, nor Nikon, nor Zeiss, nor Leica, make a wider-than-13mm lens on a full frame camera (that isn't a fisheye). Are you saying you need to go wider than the widest of the widest wide lenses that there are in existence? If you want the widest field of view, you want an AF100 with the 7-14.

Rap star like it wide YO!
Yes im looking for something like this but this is a f4 lens, im just waiting for a better option. I already have all the others lens that i need, i just dont have my wider than the widest of the widest wide lenses at the moment because there is this crop factor, but im full equip and good from 40 to 200mm.

Why is f4 a problem. F4 on the AF is plenty shallow and probably right where you want to be.

When discussing super wide focal lengths, I'd simply focus on the maximum lens aperture for reasons of exposure. Worrying about attaining open apertures for the purpose of shallow DoF on wide angle lenses (esp. for wide shots) will be futile. DoF will only get shallow, IMO, when focusing under 5 feet or in that area. DoF and wide telephoto lenses are not usually found in the same sentence. You'd have to drastically shorten the camera to subject distance to get any out of focus elements in the image. Be prepared for some deep focus.


For example, if my math is right:

A 7mm lens at a very wide F/1.4 with the subject a very close 5 feet away, still has 11.5ft of DoF!!! If the subject was just 24 inches from the plane of focus, there would still be a 1.12 foot DoF... almost unheard of to those who use more normal or less wide focal lengths. A 14mm lens at a very wide aperture of F/1.4 with the subject a very close 5 feet away, has 3.66ft of DoF.

[Julienmassie]

I just want more than f4 to shoot in low light ... I dont want depth of field in these situation, i just want to open my iris more than f4 to have more light during street night shoot. I will just use other lens to get DOF when i need it.

[Barry_Green]

These are fisheye, but they're extremely wide and faster than f/4:
Peleng 8mm f/3.5
Panasonic fisheye 8mm f/3.5

These are awesome, rectilinear, and way faster than f/4, but probably only rental items. Still, rent 'em for the day when you need such a special-purpose lens:
Zeiss Ultra Prime 8mm f/2.7
Zeiss Ultra Prime 10mm f/2
Zeiss Standard 10mm f/2

if you already have the lumix 14-140mm, would you prefer to get the 14mm 2.5 or go wider and get the 7-14mm 4.0?
