I am considering picking up a Zeiss conquest 3x9 in either 40mm or 50mm objective. My question is , is there a noticeable difference in low light performance to justify the extra $100.00?

With a one inch tube I would stay with the 40mm. I do not like the 50 mm unless I have a 30mm tube. Instead of spending the extra $100 on the Zeiss I would consider a slightly better scope in 40mm. I do not know how much the Swaro's one inch A line scopes are now. But I have one and it is truly my all time favorite deer hunting scope. It has the perfect compromise of size, weight, and superior optics. Take a look at one. Tom.

The Swaro will be outside my budget unfortunately.

I had the Zeiss Conquest 3-9 x 40 mm for a little while and found it just didn’t set up well with my short action rifle. The optics were good but found the field of view a little on the narrow side as well as the body being very long. I have the Zeiss Conquest 3-9 x 50 mm model set up on another rifle and as much as I mentioned in the past I wouldn’t get another 50 mm scope . I find this one is excellent and had a price I just couldn’t pass up. As for low light conditions, it works very well. Is it worth the $100 more, that I can’t say...

Look at it this way, the scope will last 40+ or more years, so that is less than $3 extra per year for the 50. I would get the 50.

I have a few Zeiss scopes in both 40, 44 and 50mm. Get the 50mm, as good as Zeiss glass is, it's even better through the 50mm during low light.

I have a 3-9-50mm and a 4.5-14-44mm,both excelent but the 50mm is much better at dusk...

I never could stand 50mm scopes for the simple reasons being you have to mount the scope higher. In fact,with most rifles comb height,you'll lose good cheekweld unless you have hogjaws. I'm a big guy and I have to lift my head up off the comb to see thru 50mm mounted scopes. With a properly fitted rifle/scope/mounts combo-you SHOULD be able to simply raise the rifle to your shoulder and automatically be ready to fire without having to lift your head off the comb. When cheek isn't solidly on stock,it's not conductive to good,fast target aqquiring form and you lose valuable time and some precision under normal shooting/hunting conditions. With a 40mm objective lens scope,you can mount it lower. That's the MAIN reason I ABSOLUTELY HATE see-thru or ironsighter scope mounts.

I recommend the 40 yo can use medium rings with it were as you have to have high rings with the 50 and you don't get as good of a cheek weld on the rifle.

I would choose the 40mm scope because it can be mounted lower,and will be plenty bright for hunting during legal hours.
