Greetings!
Several months ago, I had the opportunity to evaluate the 8x42 model Alpen Apex at a local sporting goods store. I was quite impressed with the optical quality of the unit I examined, and that evening I made a posting on BirdForum with my (quite) favorable impressions. Several days later, I decided to purchase the pair in question, and returned to the sporting goods store with cash in hand. Unfortunately, they had sold the only 8x42 they had in stock (the one I examined) but assured me that in a few days a few new pair would arrive in an expected shipment.
I returned to the store a week later, to find that the shipment had indeed arrived. There were 2 pair of 8x42 available for purchase, but being somewhat picky (as usual) I insisted on evaluating the unit I would be purchasing before the transaction. I found the new pair to fall somewhat short of the pair I examined a week before, with noticably higher levels of CA and edge softness. Figuring this was somewhat of a manufacturing fluke (the "pair they made on Monday"), I asked for the other boxed and sealed pair. They reluctantly allowed me to open the box and examine the 2nd pair available, and after a short evaluation I could tell that there was something obviously wrong. I finally figured out (by closing one eye, then the other) that the pair was SERIOUSLY miscollimated, although the optical quality appeared to be slightly better than the previous pair - although still not up to the standards of the pair I examined a week before. I left the store without making a purchase, needless to say.
Two morals to this story. First off, if you find an optically exceptional pair of binoculars you are interested in buying, BUY THEM. Don't expect future shipments to be the same, or even units in the same batch to be. Second, ALWAYS examine the pair you are purchasing, don't make a purchasing decision based on a "display" model then buy an unopened boxed pair expecting the same product.
Moral lessons aside, my impression of the Alpen Apex binoculars is mixed. It is apparent to me that there are some VERY good specimens available, but quality control and consistency seem to be hit and miss. Try before you buy, and you won't be sorry.
Best wishes,
Bawko
