MV-CU050-90UM

Trade-off — needs agreement

The search threshold is met, but this is not a replacement without trade-offs.

Trade-offs to settle before you choose:

Frame rate: 59.8 instead of 72 fps (-16.94 %).
The lens mount differs: check the fit and the flange distance of your current lens.
Pixel size, X: 2.5 instead of 2.74 µm (-8.76 %); the field of view will change with the same lens.
Pixel size, Y: 2.5 instead of 2.74 µm (-8.76 %); the field of view will change with the same lens.

With the same lens and working distance, on the full frame, the field of view changes: -3.09 % in width, -3.77 % in height. A smaller image circle is required — part of the field the existing lens covers goes unused.
