Sensor Size Comparison and Field of View (F.O.V)
|
Image sensors (CCD, CMOS etc) used in digital cameras vary in sizes depending
on maker and
its model. Please refer to below charts describing relation between microscope
Filed of View
and shooting range of photo and select correct adapter for your particular DSLR model. |

NEX has short flange focal distance and may generate vignette depending
on types of objective used. And so NY-1S35 is recommenced |

How to find F.O.V
for Olympus Eyepiece
【GSWH10X/22】
|
 |
GSWH : model name
10X : magnificaition
22 : F.O.V (φ22mm) |
|
| 1 |
Shooting Image is based on the area visible with a 10x eyepiece |
| 2 |
Make sure F.O.V of you particular eyepiece model |
|
It varies even when magnifications is same |
| 3 |
Common F.O.V range for high magnification microscope is 18-22 |
|
Common F.O.V range for is 22-27 |
|
|
| ★ |
Peripheral image of objective is distorted and out of focus compare to
the center area. Our adapter is optically designed to have shooting range
within the FOV and able to capture quality images even to peripheral. |
