Sony intros Alpha DSLR concepts, ‘ultra-compact’ interchangeable lens model included

PMA is just kicking off in earnest down in Anaheim, and it looks like Sony has arrived in a big way. Looking to make a splash in a DSLR world dominated by Canon and Nikon, the outfit has brought a few of its best and brightest concepts to SoCal. Up first is an ultra-compact "interchangeable lens" concept, which is no doubt Sony's attempt to get in on the fledgling Micro Four Thirds game before it blows up big. Few details on the device are available, but we'll be doing our best to pry whatever specifications we can from the booth representatives in short order. Moving on, there's a conceptual model of the Alpha A700 replacement, complete with an Exmor APS HD CMOS sensor that promises full AVCHD video capabilities. There's also a prototype of a Super Telephoto Lens (500mm F4 G) as well as a prototype Distagon T 24mm F2 ZA SSM, which ought to make wide angle junkies drool profusely. The company's also dishing out a raft of accessories, including underwater housing devices, HD lenses and output cables, tripods / accessory packs and a Compact PictureStation photo printing kiosk. Stay tuned for some hands-on action from the show floor.

How To Choose The Best Binoculars For Your Needs

So you are in need a pair of binoculars, but you are clueless when it comes to knowing just how to go about a href=http://carlzeissbinoculars.net target=_blankchoosing the best binoculars/a for your requirements. Perhaps part of the problem is that you dont even know what your requirements are? Not to worry however, as this is a common problem that all of us are faced with at some point in our lives when pursuing a new hobby or interest.br /
br /
A good starting point to choosing a pair of new binoculars is to consider exactly what you are going to be using them for. Sadly in the world of binoculars there is no such thing as a one size fits all pair of binoculars – each pair is manufactured to cater to for a specific set of requirements.br /
br /
One of the first things youll want to consider is the amount of magnification you require – also referred to as the magnification level or magnification factor. Obviously the further away the objects you anticipate to be looking at, the larger magnification level you will need. This is similar to the zoom feature on a digital camera in the sense that a number measures the amount of times the objects you are looking at are magnified in comparison as to when looked at by the naked eye. Quite simply, the larger the number – the larger the magnification level – the closer objects will appear.br /
br /
One thing to be weary of is that if you choose a magnification level too large when youre only looking at objects at a reasonably close range, you will have a hellishly difficult time trying to hold your binoculars still enough to be able to get a comfortable, steady view. This is because as objects within your field of view become magnified, small hand movements and unintentional twitches become more pronounced also.br /
br /
Once youve established what level of magnification you require, youll need to consider what size or type of objective lens you will need. The objective lens is the largest lens on the front of a pair of binoculars, and is measured in millimeters. Choosing the correct type of objective lens can mean the difference between a pair of functional binoculars, and a pair which are rendered absolutely useless in certain scenarios and environments.br /
br /
The larger the objective lens, the more light will obviously be sucked in by the binoculars. This will result in a brighter, more vivid image. Whilst the difference might not be so noticeable in wide open spaces on a sunny day, you would certainly be kicking yourself to discover that your objective lens is too small to absorb sufficient light under a cluster of shady trees, thus rendering them unusable on a hunting trip or bird watching expedition.br /
br /
Whilst a bigger objective lens is nearly always better (and will often also provide a wider field of view), the major drawback to having them bigger than what you need is quite simply the increase in the size and weight of your pair of binoculars. If youre carrying them about all day, the last thing you need is a pair of binoculars hanging around your neck that are many times bigger and heavier than they need to be.br /
br /
There are course numerous other factors to consider when choosing a pair of binoculars, but these are two of the most important and are definitely the two things youll want to consider first off. Indeed, all binoculars manufacturers offer a vast selection of binoculars within each of their model ranges with different combinations of magnification levels and objective lens sizes, particularly the bigger manufacturers of more professional binoculars such as a href=http://carlzeissbinoculars.net target=_blankZeiss binoculars/a. Many of the other features of a pair of binoculars are there mostly for convenience and ease-of-use, whereas choosing the correct objective lens type and size and magnification level is crucial to your binoculars ability to serve their intended purpose in a satisfactory manner.br /
