Question: What is the shortest distance you can focus on with these?
Document: I use these all the time and love them. They are lightweight, good for close or distance viewing and perfect for hiking or travel. I can fit them inside a large pocket on my vest or carry them around my neck. I like them better than another pair I purchased for twice the cost but which never get used since I bought these.
Out of the box, the parallax of the left and right views was off by 12&#34; over a thirty foot distance. That means the images are so shifted in the viewing plane that the binoculars are completely unusable. I would have thought that a brand such as Pentax would have manufacturing and quality assurance practices in place that would have prevented this from ever leaving the warehouse.Disappointing? Without a doubt. Would I buy a Pentax product again? Not likely.
Good buy! Very clear viewing. Easy to adjust and focus. My wife loves them. The price was right for the application.
The binoculars are very nice. Easy directions to focus both eyepieces. Would highly recommend these. Great for the price. The field of vision is more than adequate.
I bought this binoculars for my husband based on the reviews. They lived up to the ratings. My husband actually thought they cost 3 times the amount I paid for them. Very sharp focus and easy to use.
I read all the reviews and I took a chance and order it, they are very light which I truly love, good for birdwatching and close views. Takes a while to get focus, but once we learn how to do it, no problem. It was a good buy.
I'm not sure if this is because of the way the prisms work. I read that some prisms have different coatings for light to automatically compensate for the varied degrees of brightness. But adjusting the focus slightly takes care of the issue. Not a deal breaker, just a slight observation.buy em.
Needed binoculars for a safari but didn't want to spend a lot (since I don't have a use for binoculars otherwise). While these are a little odd looking, they worked perfectly and are solidly made. Easy to focus. And I liked the fact that a case and lens covers were included. Highly recommended.
I purchased the Pentax 8x25 binocular for an Alaskan cruise. Wow, I have been happy with this purchase. They are very compact and easy to carry about without being heavy or getting in the way. The carrier actually can be strapped to your belt. The clarity when looking through the binoculars is outstanding. The ease of focus and the image is extremely stable. I wouldn't hesitate at all to recommend this set of binoculars.
But they have a great image quality, very sharp, easy to focus, and reactive. Most binoculars i've use cannot adjust quickly and it's hard to find your target, especially if it's moving. Great for bird watching, especially humming birds up close. I'll also add that I wear perscription glasses and was worried I wouldn't be able to see well without my glasses on.
Answer: Focus wise it can be as close as less than 6 feet for my eyes (I think it depends on viewer's eyesight). However, the real problem is the images from two eyes don't over lap very well when the object is this close. If you want to observe something that close, Pentax Papilio is designed for that purpose and has very good reputation.
