scope question
What kind of quality/light gathering ability difference would you have between the Zeiss Conquest 3x12x56 (1"tube) at about $920 and the Zeiss Diavari VM/V 3x12x56 (30mm tube) at about $1600? Is it worth the difference?

RE: scope question
this is where people dont know what they are talking about, yes the objective helps alot you will gather more light with a 56mm than a 40 mm, we all know that but a huge factor is the size of the tube and the kind of glass, these two are huge factors in price of a scope, tube is also huge in light gathering, hope this helps

RE: scope question
I personally don't think tube size matters one single bit. Most 30mm tubes have the 1" innards anyway. Good glass and exit pupil has more to do with it.IYAM.
It is my belief that the 30mm tube stuff is all hype, aimed (no pun intended) at selling scopes. For the most part, Eurpean scopes have been known to be the best made and they use a 30mm tube. Why? Cause they are on the metric system. Sure it may add a litte bit of strength (and weight), but I just can't see it doing any more than just that. My Leupolds with 1" tubes seem to be holding up just fine. Stick a 30mm tube on a cheap Tasco and you know what you got? Still a cheap Tasco that sux. With a 30mm tube of course.

RE: scope question
Yes objective makes a difference but the type/quality of lens used and coatings make up the meat on light transmission. The better the glass and coatings the less the objective will make for usable light transmission. Scope with superior coatings with smaller objectives will out perform those with larger objectives and low quality coatings. Comparing apples to apples it should be bigger objective more light but the human eye can only take some much light and the rest is wasted so it will become a point of diminshing returns. For most application good quality scopes of 40-50mm is all a biggame hunter needs for legal hours. By putting a large objective scope on you may change your shooting position which can result in poorer accuracy and scope crowding(which can lead to the ouch of be SF'd). This is subjective as some find med mounts to be perfect, while others find lower or higher to be aok. I just say this point so you take it into consideration before you purchase any scope(mount height and what it may or may not do to your shooting position.)
It is argued that a 30 mm should return more light than a 1", however the real benefits are internal strength and adjustment gains in the 30mm vs 1". The real difference is as stated above to get light transmission gains, not tube size. The advantage in tube size is so slight I would venture to say it is almost not measurable in light transmission on comparable glass and coatings.
The diavari is superior in glass and coatings so it should be brighter, clear, etc. I also would venture to say it's component make up would be more superior. This would account for the price difference. Is it worth it? Only you can make that call. Personally I wouldn't buy the diavari as the Conquest is all the scope I need for my hunting needs. I also would never buy a 56mm as my 40-50mm objectives of different manufacturer's is all I have ever needed for hunting in low light(legal times). While some are brighter not even the smaller objective's on my cheaper scopes have lost me in the field. Yes, some days it is too dark to distinguish and is legal but part of hunting is waiting for confirmation and that can mean not taking a shot, it is never a mistake in my mind not taking a shot that your not 100% confident in all aspects. I doubt in those rare cases any scope would have bought me the confirmation I needed to make the shot...I may be wrong just my opinion. Again it is personal and depends on your situation.
I would say do some research and take some boo's through the scopes available for your needs. The man who holds the check hold the desicion and everybody is different in what they need, want or see benefit in. Good Luck.
