Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : The question I was most keen to answer was, does this model share the bright, transparent colours that the 8x40 has? Are you the sort of shooter who appreciates the benefits technology has to offer, but likes to keep things simple when it comes to a sight? If so, the fixed-magnification 10×40 prismatic scope from Immersive Optics is one for you.
When trying the SFL 8x40 for the first time I initially found the focus way too stiff although it eased considerably with use and became quite comfortable by day two. This did not happen with the 10x unit as it was comfortable straight out of the box. Talking of which, it also came with objective covers already fitted, and while I have never used these in the past, I was impressed by these. Whereas other objective covers I have experienced have been rather crude rubber flaps attached by simple rubber rings, these not only appear to actually be the work of a design studio (see pic) but, amazingly, also the work of the same design studio that styled these binoculars, the covers even having the Zeiss logo on the inside as well as the outside! I can’t believe I am suggesting that objective covers can be stylish, but it’s true. So I decided to leave them in place. This was our 20th visit to Islay at this time of year, and we have also been 7 times in the Spring, so we know the island very well. Islay is almost split in two, by two sea-lochs: Loch Indaal from the south and Loch Gruinart from the north, and indeed the land connecting these two parts is so low that I am sure that from a distance it could look like two separate islands. The western portion (where we stay) is called The Rhinns and has a distinct flavour of its own, with its west coast facing the open Atlantic Ocean, while the eastern, larger portion, has a long rather sheltered eastern coast, facing across a narrow sound to the Isle of Jura, and across a wider channel to the mainland. For any parabola, Ax 2+Bx+C,the x-coordinate of the vertex is given by -B/(2A). In our case the x coordinate is 5.0000 Offers up to 4x wider field of view when compared to traditional sights and can focus down to a distance of 6m for close-range shooting.I do consider the Pentax ED's just below modern Alpha binoculars so really for 40 year old binocular the Leitz’s do hold up remarkably well which is tantamount to the original excellent optical and build qualities. This optic is side-parallax-adjustable down to six metres. It has a choice of two different reticles, Mildot, which is the one on test here, or the more complex Mildot Extended, which provides more aim points. It measures just 135mm long and weighs 485g, including the supplied single ring mount. I have observed for 40 odd years and have 30 odd mainly Hi-quality binoculars in my collection I would count the Leitz’s in my top 5. Though genuinely happy with the overall optical performance, I couldn't personally get on with the ergonomics and in spite of persisting found that most of the 'steadier' grips needed all sorts of fumbling gymnastics - especially if wearing gloves. The only grip that I could muster that felt natural and comfortable was, unfortunately, also the least steady. For me, anyway, the whole thing would have just plain worked had the binocular had a more 'conventionally' placed focus wheel. decent. I watch the waders on the sands settling to roost. But these don’t have the quite the deep dusk and moonlight penetration
I like the Mildot reticle. In my opinion it has just enough aim points to be useful, while still maintaining a nice clean image. The mounts offer the ability to add inclination or declination to the sight so it can be kept optically centred while being zeroed
x*(10-x)-(40)=0 Step by step solution : Step 1 : Equation at the end of step 1 : x • (10 - x) - 40 = 0
