Sigma 150-500mm f/5-6.3 AF APO DG OS HSM Lens Review
The Sigma 150-500mm f/5-6.3 DG OS HSM, the company is the latest offering in the extreme telephoto financial marketplace and kicks in a couple of eyebrow raising surprises! Replacing the 170-500mm model, which is now pretty long in the tooth, the new lens has a good specification for its price.
Build and handling
The construction and operation of this lens is a significant jump up from his predecessor and bears a strong similarity in the type of well-liked 50-500mm EX model. The conventional twin-control rings have to focus on the back, while the front ring controls the zoom function to extend the run, as it does so by some 64mm. The lens has a zoom lock to this extension, if not to stop in use.
The HSM and OS functions have the lens a bit heavier than the old 170-500mm, although it is still at a manageable weight of just under 2kg. And vice versa with the supplied cap on the barrel, the lens will still fit in most camera bags, this is for a 500mm lens even more compact. The front-on 86mm lens, however, is a great, what an expensive extra filters.

Control switches are all on the left side of the barrel, and consist of an AF/Manual switch for focusing and a OFF/1/2 switch for the OS system. With the HSM AF motor drive it is possible to manually over-ride the auto focus without turning off the AF.
The OS or optical stabilization, Sigma version of the in-lens stabilization and works well, although with a slight whimper and run a small thump as it engages or is dissolved. It is noticeable only in quiet conditions, however, and is certainly not intrusive. The No. 1 position governs movement in both horizontal and vertical plane, while the No. 2 setting compensates for movement only in the vertical plane, so that the pivoting motion of the camera without interference. At full extension of the focal length I found it possible, sharp images up to around 1/100sec quite successful. Good technique is still a long lens requirement but in the use of lenses with so much traction.
To this the lens with a significant stand clamp, can double as a carrying handle equipped, although it is remembered should turn off the OS system should be turned on when a tripod may be used.
Focusing is the biggest improvement over the single lens’ predecessor, with this very quickly in comparison. Tracking moving subjects is a breeze with this model and it is even able to catch up with them, which dealt with the older version is rarely successful. There is no sign of hunting, until you at very low light, something that bodes well for the contrast that the lens is able to obtain.

Optical power
Keeping the zoom to 3.3x Sigma have the complicated trade-offs that go in, avoiding, for example, their 50-500mm lens, and that has value in the image quality department. Contrast, if not spectacular, is certainly good and, as already mentioned, is certainly helpful, focused and modern systems. No noticeable distortions are recorded, not that telephoto lenses usually have a problem with this aspect.
Chromatic aberrations, the dreaded fringing purple that contrast image areas can mar, never its ugly head during the test held, despite some very high contrast situations, even though they are on a full frame camera, there are some indications of light blue/red fringing on the very edge at the longer end of the zoom. This, however, were small and included no occurrence of scattered light, although decently deep hood was used over the whole period. These results were consistent right across the entire width of the frame. The lens also focused on a respectable 2.2 and still managed to produce high quality images.

Verdict
In terms of features versus price performance ratio of this lens to the telephoto bargain of the century to date. Both Sonic with a focus system and an optical stabilization system, two of which work well, with a good optical performance and compact dimensions is reasonably linked, I can see, this look will find a lot of admirers. If the pull of a 500mm in a manageable package want, they should be comparable to the top of your list!
Sony DSC-W350 Review
The Sony Cyber-shot DSCW350 is the latest offering from Sony. There are a lot of competition in the $ 200 segment, strong competition from Canon and Nikon. The Sony Cyber-Shot lens 26mm f2.7 with good is equivalent wide-angle, 4x zoom, optical image stabilization, an HD movie mode and 2.7″ LCD screen. Cyber-shot is pretty small and attractive and provides a reliable functions for snap-shooters. The picture quality is excellent with this 14-megapixel camera. But the shooting performance is modest. It allows you to pictures at even ISO sensitivities such as ISO 1600 and ISO to take 800th, see collect very good experience and it snaps at this price tag.

We accept the fact that this feature is not as good as Sony’s Exmor models such TX1 and WX1. The movie mode shoots the video in 720p HD resolution. In addition, with a microphone, the audio recordings during the shooting.
The performance of the filming is mixed bag. The shutter lag is modest. In bright conditions, it consumes only 0.4 seconds to press to release button. In low-light, it takes about 0.7 seconds. The W350 is very fast, while shooting, it records at 1.9 frames per second. Time to take first shot is 1.9 seconds.

The sensitivity is good between ISO 80 to ISO 3200 staggers, then. Even at ISO80, the images look better. Noise will be added as increased sensitivity. If you add the form of noise reduction feature watery effect to drink, you get soft and painted into place. If you try to shoot more than 4×6″, keep the ISO at a lower level as far as possible.

Sony 75-300mm f/4.5-5.6 Lens Review
The Sony 75-300mm telephoto lens SAL75300 was started with the A100 digital SLR as part of an optional Twin Zoom Lens Kit. While most people it is as part of the A100 Twin Lens Kit, 75-300mm is now also buy individually. As such, it is probably going to get the most popular telephoto for the A100 DSLR be.
The Sony 75-300mm is designed to complement the standard 18-70mm kit lens, greatly extending the range without overlap. In fact, since the 5mm difference between them is negligible, the pair offer a huge range from 18-300mm, providing a 35mm-equivalent range 27-450mm. The telephoto end of the 75-300mm is ideal for portraits, animals and sports events, along with-bring in any kind of distant detail. And since the Sony Alpha A100 body has built-in Super SteadyShot the 75-300mm anti-shake capabilities automatically enjoys.
In this paper we present the Sony 75-300mm zoom through its paces and see how it complements the standard 18-70mm kit lens. We have the optical quality of the reveal to the 75-300mm 18-70mm, compared to what you can expect when switching from one to another. In some cases, leads one better than the others around the 70-75mm mark, we’ll let you know what the objective should be for the best results.
The 75-300mm measures 71×122mm (diameter by length) and extends a further 56mm using a single barrel section when zoomed-into 300mm. The 55mm filter size measures and weighs the lens 460g. A lens hood is included.

It employs a 75-300mm optical design of 13 elements in ten groups with seven aperture blades and has a minimum focusing distance of 1.5m. The lens does not employ internal focusing and actually extends a further 13mm in its entire focusing range. The front part and also rotates while focusing, which is annoying for users of polarizing filters. There is no focus distance scale on the lens, so it is really mostly designed for AF operation.
Concentrating on the 75-300mm was not very fast to shift with the lens at a good second through its entire range. The engines and transmissions were very audible, and divert it to prove, if you could shoot in a quiet room or environment. To be fair, it’s just a little louder than the standard 18-70mm kit lens when focusing, but it’s not just a quiet operator. If the noise of the kit lens does not interfere, when the 75-300mm should be no nasty surprises.
The Sony Alpha A100 features Super SteadyShot which means any lens you attach to enjoy anti-shake capabilities. This is one of the big selling points of the A100 and seen to have a good performance with the 18-70mm kit lens, we were curious to see how effective it would be with the longer 75-300mm. Since the 75-300mm has an effective range of 113-450mm, traditional SLR technology would recommend using a shutter speed of 1/450 or higher, to avoid camera-shake when zoomed in fully. The big question is how Super SteadyShot would treat slower exposures.
Since the camera can stabilize even physically shift the sensor by the same amount, regardless of the lens insert, it is also less effective than the focal length increases. This has always been the case for Canon and Nikon in-lens stabilization of the focal length can be cut in question. The above results show, surely the A100 anti-shake system with lower compensation at longer focal lengths than for shorter, but is also in this one single example of a person on a given day. However, it is an issue which we must be examined closely and look forward to retesting of the Sony A100 with other long lenses in the future to see if the Anti-Shake-effectiveness of the 3.5 stops of compensation available to to keep shorter focal lengths.

The Sony 75-300mm lens is designed to complement the standard 18-70mm kit lens, and although they are often sold as a bundle with the Twin-A100. Since the 5mm difference where one ends and the other begins, is essentially irrelevant, the two offer a broad spectrum of 18-300mm, or an equivalent of 27-450mm, wide angle to telephoto provide long skills.
The Sony 75-300mm is a very useful addition to the standard DT 18-70mm kit lens, are significantly expanded the bandwidth available to powerful telephoto equipment. This makes it ideal for portraits, sports and wildlife photography, or simply closer to each remote motives.

Canon EF 35mm f/1.4L USM Lens Review
On 35mm cameras, the lens is in the starting area for wide angle, but to cut DSLR it is more of a standard lens. However, it is a very fast lens that can be applied in situations where “normal” lens is not able to deal with it. We take a look at how it performs.
Build and handling
Prime lenses, but can very easily, after some of the modern zooms and the simplicity of use makes it easier to achieve the build quality. A single focus ring is in front of a window, the classic distance with a useful depth-of-field scale marked pretty well sums up this lens. The only other control on the lens is the switch that changes the focus from manual autofocus.
The lens seems a little large compared to say, a 18-55mm zoom, but this is due to the wide aperture, this lens sport.

Autofocus is nearly silent at all on a 1D, very quickly through the USM motor and not hunting although it works a little think about it in dim light on a 300D. We only call attention, because it did little else to complain about the handling of this lens.
Optical power
As you would expect from a fixed focal length, especially with Canon’s famous L suffix, was the good optical performance. You will see from the chart that a gentle curve achieved with no wild jumps from one source to another, always the sign of a well-produced lens. In addition, possible to start from a decent performance wide open, showing that it is not beyond what it has been designed in advanced.
The only place, it is abandoned, and only slightly, is in the control of chromatic aberration. Since it is not a new lens and is initially designed for 35mm, has completed the inspection of these anomalies on a long way to come since the introduction of digital and this lens is located behind a little with modern techniques.
Verdict
The build quality and heritage of his lens is undeniable, and for full frame sensors or 35mm, it is still in the top group. As a standard prime on a cropped sensor dSLR it will do a good job, but could only be performed by some of the younger opposition.
