First try with the Vipers was a bit disappointing, My reference bins, the broken Pentax Porro 10x50 I have always thought pretty sharp and The Vipers aren't really any sharper. I rested my eyes for 5 minutes and looked again re adjusting the diopter. Another 5 mins rest and just a tiny touch on the diopter and they are perfectly set.
The PPP's on the other hand are a real fiddle as I have to move the left ocular back in to the tube manually as they are broken and the diopter has always needed constant tweaks as the oculars have a little play in them but a few minutes and I'm ready to compare the look at a neighbours satellite dish on the apex of the roof. This time the vortex look sharper but only very slightly.
I was expecting the vipers to be pretty much excellent on sharpness and maybe they are, maybe the PPP's are pretty sharp themselves even by today's standards. The Vipers focus knob feels perfect with no notchiness or gritty feeling just smooth, perfectly weighted at least to me and very fast. From 25 to 50 yds I barely touched it a tiny bit more and I'm out to 250 yds.
It's a grey evening and neither pair show any false colour on branches against the sky though I know the PPP's do suffer from some chromatic aberration on bright days so I will try to this test again when the sun is out.
I then checked the alignment/ collimation as I've read of problems with some but the image was identical in both eyepieces. I checked both horizontal and vertical planes and tho I'm no optical engineer they appear perfectly aligned which was a relief.
I thought I'd try the trees 50 plus yards away over the rooftops and found a very pleasing fork in a Silver birch with some mid grey mottling and patches on the silver bark. Not very contrasty at all The PPP's after a few minutes of fiddling provided a nice sharp image. The Vipers instantly snapped into focus and something was very apparent, the image was much more pleasing and detailed tho not massively sharper. The Viper's are showing a lot more contrast and somehow a much prettier image.
I then went for a look in my back garden from a bedroom window here the Vipers really impressed with lovely views of the shrubs and small fir trees presenting beautiful sharp and somehow very pleasing views. The PPP's started to look very lack lustre by comparison. I'm trying here do describe something indescribable, sure the Vipers showed a tiny amount more sharpness and a little more detail but the image was just so pleasing I felt I wanted to keep looking at it. I'm no expert on using binoculars tho I do have a fair knowledge of optics and I can say the Vipers serve up much more pleasing views than the PPP's and as the evening light began to fade they looked brighter too, this surprised me as the PPP's are 10x50 and the vipers are 10x42 so I actually expected the opposite. I guess the newer coatings do work after all!
I then looked at my car, it's almost black and the raindrops on the bonnet and badge were gleaming with reflections, the PPP's were very good but the Vipers just easily beat them, again the view was just more immersive. The PPP's image "appeared" flat but the Vipers looked almost 3 dimensional and just more detailed without any glare from the droplets.
Initial fairly thorough testing of the Vipers completed and though I'm not overly amazed by the improved sharpness I am quietly impressed by the gorgeous image.
That's all for now more to follow.
