lenses ??? Wide and Fast
A 14mm was my favorite (and most often used) lens back in film days. Which company currently offers the "widest" equivalent ??? Is it the Oly 7-14 ???.

Does anyone offer a prime lens in this range that may focus CLOSER than the 7-14 may ???.

Does anyone offer a f/1.2 or f/1.4 lens (in the 35 to 85 equivalent range) ???.

Thanks for reading .... JoePhoto.

Hi Joephoto.

Quite a few questions in one post. Are you referring to full frame or cropped sensor format lenses?.

Regards, Mirza.

The 7-14 will focus to within about an inch of the front lens surface, how close did you need it to go?.

And there's a 4:3rds 25mm f1.4 by Leica (equiv to 50mm on a FF). Isn't cheap.A member of the rabble in good standing..

With a wide DOF, you may get "acceptable" results down to 1" .... but .....

The spec sheet says .25 meter ... (just over 8").

The Sigma 14 (FF lens) is speced at 5.9"..

What bodies is it designed for ????.

Agreed but at f5.6 the dof is so wide that getting that close is easy. Also while the last number on the barrel is .25m it continues to move past that mark to something closer. One of the issues with the lens is that it's easy to actually move so close to the subject that you bump the front of the lens. It appears to be well in focus up to about .1m at wide open (f4).

And there's a 4:3rds 25mm f1.4 by Leica (equiv to 50mm on a FF).Isn't cheap..

Oly or Panasonic......thus the 4:3 or 4/3 designation, I should have made that clear..

Most DSLR sensor sizes are smaller than 35mm which means that lens focal lenghts do not equate to the same 35mm field of view. You may see the expression "crop factor" in this regard..

The Olympus 4/3 system has a 1/2 size sensor which has a crop factor of 2xMost other cameras are 1.5x or 1.6x sensors..

A very few cameras are Full Frame (FF) meaning they have a sensor with the same size as a 35mm frame ( or at least that the field of view equates to that )..

To find the equivalent field of view multiply the quoted lens focal lengths by the crop factor ( so the Oly 7-14 has a field of view equivalent to 14-28, for example )..

Does anyone offer a prime lens in this range that may focus CLOSERthan the 7-14 may ???.

A 14mm field of view on 35mm equates to needing either a 7mm on the Oly, a 9.5-ish on most other DSLRs. Only on a FF camera will a 14mm lens work the same. This is really ultra wide ( and heading for fish eye ).

Does anyone offer a f/1.2 or f/1.4 lens (in the 35 to 85 equivalentrange) ???.

The following site has a lot of lens info which you might find useful - it's not exhaustive, but it's a good start with excellent lens tests and reviews..
