FOV Calculator

[chrysoberyl]

Can someone provide me with a link to a FOV calculator? I wish to compare the Canon 100mm L to the Zeiss 100mm Makro to the Zeiss 50mm Makro to the Sigma 35mm Art.

Thanks in advance,
John

Thanks, Acutance, but none of the first six include magnification in their calculators, so I'll just do the trig.

From B&H spec pages;

EF 100mm f/2.8L
Angle of View 24°
Minimum Focus Distance 1' (30.48 cm)
Magnification 1x
Maximum Reproduction Ratio 1:1
---
Makro-Planar T* 100mm f/2 ZE
Angle of View 25°
Minimum Focus Distance 1.44' (44 cm)
Magnification 0.5x
Maximum Reproduction Ratio 1:2
---
35mm f/1.4 DG HSM Art
Angle of View 63.4°
Minimum Focus Distance 11.81" (30.00 cm)
Maximum Reproduction Ratio 1:5

Since you are prepared to apply trig, I suspect the specs above are not what you seek, this answer above is likely too simplistic.
Can you briefly explain in pedestrian terms just what it is you are after?

Thanks for the information, Tolusina. I have gear acquisition syndrome for one of the Zeiss lenses, and I hope to dissuade myself from spending money. I do not have a 50mm lens and I enjoy macro, so the 50mm Makro is especially appealing. The data I want to compare are DOF and FOV for all four lenses, at 1.5’, 3’ and 5’.

I just compared photos taken with my 6D and the Sigma 35mm Art and the Canon 100mm L, and although I like both lenses very much, I want more DOF than the 100mm L provides, and more magnification than the 35mm Art. One would think my decision would be easy, but I am not that experienced a photographer, so I want to review the data carefully.

More magnification, is inevitably accompanied by more shallow DOF. There is no escape from such a relationship.

Therefore, it only remains you the option to stop down to get the DOF you want.

For Macro, a limiting factor in short lens as 35 or 50mm is the working distance between the lens and the object. I prefer a lens around 100mm, which allows me to keep the lens farther away from the object and use a flash mounted on the camera's hot shoe, without the edge of the lens causes shadows, and without spending a fortune on a circular flash.

Have you tried focus-stacking?

Have you tried focus-stacking?

An excellent suggestion, but much of my macro work is wildflowers and wildlife, mostly in mountain forests. Hiking is involved, so bulky focus stacking gear is out, and windy conditions also preclude focus stacking. And the post-processing sounds tedious.

But again, thanks!
