25mm lens

Post by Ooops » 02 Aug 2015, 07:37

Hi I'm new to the whole diy NV scene, (and loving it), so you'll have to excuse me if I ask some silly questions.

I've been on your site to assemble my parts and I notice that you now offer a 25mm lens.
Is there a dedicated E700 base camera that this goes on or is it bought as a replacement lens for a camera that came with either a 12 or 16mm lens?

What are the pros and cons of fitting a 25mm over 12mm & 16mm

There appears to be a bewildering number of different 12mm & 16mm cameras but I can't tell from the descriptions what the difference are between each is.

I've seen mention of 35, 55 and 60mm lenses in various builds. Do you offer any larger lenses than 25mm?

My initial application will be rifle mounted. What are your battery pack recomendations?

TIA

G'day Jethro.
The E700 comes standard with a 12mm or 16mm lens.
A 12mm lens will give you a round picture of the scope view on your screen, surrounded by dark areas.
A 16mm lens will give you some zoom. You will see an enlarged picture of your cross hairs, with the scope image filling the screen - the curved outer areas will be cut off.
Most of us use the 16mm lens.
The 25mm lens will zoom in on the center of your cross hairs. Good for ratting, not so much open field shooting.
Larger lens are normally used on DIY digital spotting scopes.

Edited, as this is the sponsors section, so I've removed references to other products.

Hi Radagast,

Thanks for that. It was the NV car roof spotters that had the bigger lenses.
So if I've understood correctly the higher mags are not much on distance?
I've two builds in mind, the first is for the guns the second for the car but
I was hoping to buy all the parts at the same time because like you everything has to be shipped to me.

My requirements are for ratting and wabbits with magnum springers, a Condor and a HW100, all fac so those are my distances.

Have you got any pointers for battery packs?

Oh and I forgot to mention my confusion over the many variations of the same cameras that are listed.
I'm old, I'm easily confused :twisted:

Using a 25mm lens will give you some extra magnification on your scope, but will reduce your f.o.v , depends on the mag range of the scope. trade off really, a 16mm lens will give you a truer mag image, the e700 will use board lenses, more than adequate for f.a.c. air. Oh and your scope reticule may look a little thicker with a 25mm lens....

Top info, many thanks.

Is there a preferred size, type and manufacturer for battery packs?
