Scope front objective size-what is your preference?

25mm-, 35mm, 50mm+. Knowing that the bigger lenses have a higher base magnification, smaller FOV, and greater cost/weight, which one suits your style of hunting the best?

IMO, if you use the 50mm lens, as Kirsch, Skinney, DoubleUp and many other good professional night hunters from this forum teach us, you are never wrong .... You see clearly better in all conditions, daytime, at sunset , at night and at dawn, especially with cold, mist, fog, snow, rain, high relative humidity ..... For me the problem of the narrow FOV is completely secondary .... Just think that with the Infiray Saim SCH50, last night of hunting in Croatia, I caught 3 roe deer (one was stationary, but the other two were fast runners ...) with 4 consecutive shots .... If the FOV was too tight, as you fear with the 50 mm optics, I would not have been able to do this triple ....

Great answer. Good to know the magnification trumps the FOV. It is usually more important when shooting at running game. Over bait or a relatively stationary game, even less of an issue.
 
... in this post you can realize how wonderful the Bering Optics SY 50 mm (in the Infiray Saim SCH50 version) is. The FOV is much wider than that of the traditional Konus 3-12x56 riflescope which has a base magnification practically equivalent to that of the SY50 (2.91X). It sounds incredible, but it was almost easier to follow the moving target with the thermal ....

Thermal magnification and FOV is derived from the balance of the focal length, micron size, and resolution. All play a factor, so it depends. For scanners, I tend to use smaller objective lens and higher resolution to get a bigger FOV. On my scopes I either go for lower micron sizes and/or bigger lenses to get more base mag but that works for me in open terrain for coyotes. It will be totally different in other parts of the country or world in different terrains.
 
DoubleUp .... allow me to correct the calculation of the horizontal linear FOV at a distance of 100 yards with your Bering Optics Super Yoter:
640x36/500 = 46 feet .... more than you thought .... Shooting at the silhouette of the moving hog, I realized that the FOV was really very large and more than enough, as you rightly wrote ....
