Many of us adults are still young enough that a 4.2mm EP is constantly limiting in daylight, even mid-summer, such as when storm clouds come over, or you are peering into the depths of a riparian area, under banks, in gorges, under heavy canopy etc.Let's be frank - if you step outside into the full midday summer sun here, then you can quite quickly seemingly audibly hear any exposed skin start to sizzle and fry - exactly like bacon on a grill!  :eek!:  So you tend to spend a lot of time in the shade   <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite6" alt=":cool:" title="Cool    :cool:" loading="lazy" data-shortname=":cool:" />I even find that a 5mm EP runs out of puff (for me) later in the afternoon. This is one of the many reasons that the Swift Audubon 8.5x44 ED and I are no longer together, and why I haven't succumbed to the charms of the Swaro 10x50 SV, let alone the Zeiss 10x42 SF.  If the 4.2mm EP suits you fine, then that is okay by me. I hope it's okay by you though? if it doesn't entirely suit me   o<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite8" alt=":D" title="Big grin    :D" loading="lazy" data-shortname=":D" />A 9x50 SF with its 5.6mm EP would be perfect for me, and could be made light enough, and with a wide enough Fov to be a one and only bin for my purposes. The ancient magnesium tech, Vortex Razor 10x50 HD clocks in at under 800grams (28oz), and it's 173mm in length. The only problem (apart from its danged CCW focuser) is the skimpy 105m Fov, and marginal 16.5mm ER. The 42mm SF is actually a rather innovative optical design, and there's no reason that it can't scale to 50mm pretty much holus bolus, with a few tweaks as I have previously mentioned, here and there.    :cat:If you have any formal strategic training, then you will know that merely "matching the hatch" and further dividing a saturated segment is not the road to riches (although this does not seem to stop every man and his dog from bringing an SUV to market!  :-O ). You may do it for strategic competitive reasons, but that's another caper.  When it comes to the 50mm size - Zeiss is doing neither!  To be somewhat fair, they did have a crack with the 54mm HT - however it's portly parameters, woeful design standards and execution dashed more than just a few hopes ......    :-CWe're talking about a different animal here - lightweight 50mm, 70° AFov sharp to the edges, 18mm ER .... it's not rocket science!If Zeiss wants to get all 21st Century on us and use superior CFRP material for the chassis and achieve ~ 800grams for us birders (and to heck with the hairy-chested HunTers perceptions <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /> , then all the better   :t:   If not someone else will beat them to it   :king:One day far in the future, when I'm old and curmudgeonly, perhaps I will be content to just have my one and only 'classic' 8x32 SV (they should have sorted the glare issues by then! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /> , and sit around and fire cyber salvos across the bows ...... but that day is not today!Just 'imagine' what could be possible .......  Chosun   :gh:</blockquote>
