F5050 vs F4949

Postby Matsuda » Tue Sep 21, 2010 10:57 pm

I know F5050 is for ground and F4949 for aviation and both are binocular. Would you advise any other futures or differences in user's viewpoint?

Thanks,

The F5050 sure looks to be alot sturdier than the F4949. I would have really liked to upgrade my F4949 to a F5050. Look at how solid the battery pack/bridge is compared to a F4949 PAS:

You also have an actual power switch with the F5050 and with the internal battery no COPS needed for standalone use. The integrated IR illuminator is also a nice added feature for closer in illumination.

The F5050 are ruggedized and optimized for ground use. As noted by Brazos609, the pivot adjustment shelf is much more rugged than those found on the F4949 units. Another difference is the optics, being that they are optimized for ground use the objectives do not feature the coating (A, B, B mod, C, UK-645) as found on the F4949. The objectives are simply coated with anti reflective and infrared transmittance coatings. All the coatings found on the F4949 reduce system gain, which given the benefits outweigh the reduction in gain. For ground use, the reduction in gain would not outweigh the benefits because there aren't any. So, not only is the shelf optimized for the rigors of ground use but the optics are optimized as well.

I think the F5050 housing are listing for $1500 without optics.

A version of F4949 with optics optimized for ground use exists, as well.
This is the F4949RF. Unfortunately it retains the fragility of the ANVIS family.

That is not a set of F4949RF goggles. The F4949RF are for aviation use and come with class B objectives, not a pair of c-mount ENVIS objectives. The unit your calling a F4949RF has no such designation, the housings where simply modified to accept c-mount lenses, which in your case is a pair of ENVIS objectives. Whoever did the modification did a nice job though.

:!: Thanks for the insight, Stan. We have been braking our heads with a seller who offered me these as these goggles did not resemble any AVS-9 type we have ever seen.
Needless to say that I gladly bought these and still use them as my primary NV device. They are just perfect, only need to be careful handling these as they obviously can't take much beating.

AN/PVS-23 is manufactured by ITT only, F5050? No one manufacures AN/PVS-23?

Yes, only ITT. The numbers produced are not that great to justify a second source, I think.
