Is there a big differance between a 40 or 42 and a 50mm objective for light?
or does the 50mm had the advantage at longer ranges. Could not tell in a store, cannot get any distance indoors.
I guess I would like to know if it would be worth it, to put a 50mm on my 22.250?
Probably going to go with 6 x 18 or 6.5 x 20 power.
Thanks for any input!
Apparently no one wants to answer the question you asked, directly, so I will try.
Just to satisfy everyone else on here as far as scope quality goes, even though it had nothing to do with your question...... we will say we are using two scopes for this comparison. We will be using two Zeiss Conquest scopes. But note.... you could just as easily compare 2 Nikon Monarchs or Buckmasters scopes, or 2 simmons Aetec scopes.
Here is the long and short of it.
If you are using two scopes , side by side, during the daylight hours you will not be able to tell any difference,
BUT at dusk and dawn ( low light situations ) you can see a difference. say you are using a 3-12 x40 scope, and you can see fine on 9x at dusk and dawn , then the difference would be that you could see equally as well on 10 X using a 50 mm scope.
The visual equality difference between a 40 mm and a 50 mm scope ( all other things being equal ) is about 1 power setting , in the same light. a 50 mm is a little brighter than a 40 at the same power, and it will allow 1 power higher magnification to equalize with the 40mm.
SO yes, a 50 mm is better than a 40mm but not a whole lot. And it will only be noticable in lower light situations. And it is only worth about 1 power setting.
Hope that helps, AND answered your question
God Bless
