Continuing our series of evaluation of lens systems we’ve assessed a modest range of Pentax and third-party lenses for their optical quality on the firm’s new flagship Pentax K-3 model. As the replacement for the K-5 II and K-5 IIs, the Pentax K-3 has a new higher pixel density 24-Mpix sensor without an AA filter, and is a promising platform for lens evaluation. Read on to find out which models perform best, and which, if any, that should be avoided.

Manfrotto 190XPROB tripod review, 190XPROB vs 190CXPRO3 vs 055XPROB vs 055CXPRO3 The Manfrotto 190XPROB is a relatively compact and affordable tripod designed for general-purpose use. It's one of the best-selling models in Manfrotto's X range, striking a great balance between price and performance. Like most higher-end tripods, the 190XPROB does not come with a head as a standard. Instead it features a plate onto which you can mount a wide variety of optional heads to match your exact requirements. In my full review of the 190XPROB I'll compare its features and stability against three other key models in the same range, including the carbon fiber 190CXPRO3 version and the larger 055CXPRO3 and 055XPROB models. Together these four tripods dominate the sales charts as some of the best-selling models around, and for very good reason.

SLR Camera Simulator With this camera simulator you can try different aperture and shutters to affect a photos light, depth and motion blur. Try also to change the camera's light sensitivity by manipulating its ISO value. A higher ISO value gives higher sensitivity to light, which allows faster shutter speeds. Macro Rail with slider lock down New and improved Micro rail or focusing rail. Same changes compare to previous version. 1) bottom rail thickness has been change from 1/2 to 5/8 inch and additional bars across has been added to increase strength of rail Canon 10-22mm Review It's a Fine Lens – But is it a Smart Purchase? Since the first APS-C sized imagers appeared in DSLRs a few years ago, photographers have struggled with not having lenses which can provide super-wide angle coverage. With a 1.6X factor, (on Canon DSLRs, at least), a 16mm focal length, like that of Canon's 16-35mm zoom, becomes just 25mm at the wide end. Recently a number of even wider-angle lenses have become available, and the latest of this batch, at least for owners of the Canon 20D and Rebel, is the recently announced Canon EF-S 10-22mm f/3.5-4.5 USM.

Fujifilm XT1 quality In my first comparison below I chose to use variable aperture kit zooms to illustrate the kind of quality difference you can expect from each system in practice. If you're interested in the quality from prime lenses, please head straight to my noise results pages. Unfortunately there aren't equivalent zooms for both systems in range, aperture or price though, so one system will always come off worse than the other optically in such a comparison. In this case it's the OMD EM1 which suffers as its 12-50mm kit zoom is around half the price of the Fujifilm 18-55mm and as you'll see below, this shows as you approach the edges of the frame.

Cognisys Inc - Capture the Hidden World The StackShot system will allow you to easily capture multiple photographs that can be digitally combined to create a single high magnification image with a depth of field that is not possible without focus stacking. StackShot is used by many museums and universities around the world to create incredibly detailed photographs for study. It can also be used very successfully for product photography of small items like jewelry. Or, like the image above it can be used to create art. The possibilities are endless.
