Some vignetting corner shading is also noticeable at full wide-angle. At full telephoto, the right side again was softest, but not nearly as soft as wide-angle. The corners in the left hand-side were quite sharp, and the center was also sharp, but the lens had lower contrast overall at full telephoto. A slightly below average performance overall for a kit lens here. Note that the lens was "wide-open" for these shots, and corner sharpness generally improves when a lens is "stopped-down" a couple of f-stops below full aperture.
When additional surfaces are added to an optical path, especially ones not parallel with the image plane, there is always a chance that light will travel an unintended path.
In the case of the A55V and A33, it appears that the rear surface of the translucent mirror film can reflect light back to the front surface of the film, which reflects it back to the rear, causing a "ghost" reflection or multiple reflections to appear in the final image under certain conditions. Thanks to IR reader Erick E for pointing this out in one of our flash range images! The crop on the right is from a similar flash shot, taken with the same lens, but using the Sony A which is a traditional SLR without a translucent mirror in the optical path.
As you can see, under nearly identical conditions the A's flash is a bit stronger , no ghosting is present. We only found ghosting in a small subset of our test images, as it seems to require fairly specific conditions to be noticeable.
Dave also saw this phenomenon in some night shots he has taken with the Sony A55V, which we hope to share some crops from shortly. From Dave's experience, the ghosting seems to require a very concentrated light source, sharply focused, and ideally a relatively small light source with darker areas surrounding it. The ghosting did not appear with larger, less sharply-defined light sources, or when light spilled from the source on surrounding areas thereby making the lighting broader and more diffuse.
Under conditions of really severe light overloads ghosts seem to be masked by lens flare. Should you be concerned about it? Some people would certainly find it objectionable, especially if they did a lot of night photography of things like cityscapes.
Personally, it wouldn't deter us from buying a Sony A55V, because we don't do much cityscape-type photography: Our night shots tend to be ones where the subjects are people or areas lit by nearby light sources. With these sorts of shots, ghosting of the type shown above wouldn't be an issue. Bottom line, you'll need to decide for yourself if this would impact your personal style of shooting enough to outweigh the benefits of the Sony A55's pellicle mirror design.

Kurt Munger. Dyxum - dedicated to A Mount. Photozone - Sony A Mount tests. Your has the same amount of zoom as a they are both approximately 3x zoom. Then you have ultra wide angle, like And super telephotos Lenses that reach as high as mm lenses.
The sharpest lenses tend overall to be prime lenses. No zoom at all. One focal length only. It may be the sharpest lens I have ever owned. It is mm Which is a telephoto length. But can't zoom in and out.
They may super zoom lenses that start wide and go to telephoto. Such as the Tamron But such lenses won't typically be any sharper than your kit lens, they may even be inferior image quality to your kit lens. But with the convenience of a single lens that can do ultra wide to high telephoto. The best image quality zoom lenses tend to be no more than 3x-4x lenses. They can be wide or telephoto, but not usually both.
About the same focal length you are currently using, but a little bit wider. Faster larger aperture so better in low light , and much much sharper.
So it's really about, what do you want. What is your priority. Better low light? More telephoto reach? Assuming you don't want to break the bank, I'd say Sony's easy choice primes were a good place to start. Other than that, if you stray into telephoto, the Sony or Tamrom lenses are reasonable value, or if you want something a bit longer the cheapest Tamron is reasonable quality. As already said, all A mount lenses are compatible with your camera, except maybe a few older Sigma lenses which have had problems with the Sony software on SLT?
The first place to start is to analyze you own needs based on experience with your current lens. Are you just looking for more sharpness? Do you want a longer focal length or a wider angle? Are you looking for a faster lens? I see no reason to just buy a bunch of lenses for the sake of getting lenses, but do see buying them to fill specific needs. You will often get recommendations on this forum which are based on the needs of the person making the recommendation, and their needs may not be the same as yours--in a great many cases they certainly are not the same as mine.
When you have gotten some idea of this a good place to look over available lenses and reader reviews is Dyxum. The latter two sell new lenses as well. After doing this research this forum will be more helpful to you if you can give them specific information as to your needs and lenses that look promising while asking for opinions. I am sorry to tell you but in my experience the Sony is a pretty sharp lens. I have many thousands of excellent pictures taken with it and my A There are many places that is falls short but in my experience there isn't a massive amount of sharpness to be gained over it.
Where you'll find an improvement is with astrophotography. That's a scenario where you'll want to take advantage of the 1-to-2 stop advantage the Tokina gives you. Having built-in filters is a good inclusion because the lens has a petal-style hood which prevents a lens filter from being put on the front of the lens. This lens has almost everything you could desire from a fisheye.
You can get the exaggerated distortion, but the image will be tack sharp from corner-to-corner without vignetting. The lens contains a rounded front which means filters cannot be attached. It comes with a snap-on petal-style hood that you'll want to ensure is included if you get a used copy. Construction quality can be somewhat hit or miss as a consequence of the low price of the lens. A majority of owners are quite pleased with the results they get. You will nevertheless want to extensively test the lens when you receive it to know for sure that it is not a defective copy.
The perfect balance of price, working distance, and weight for the Sony A The autofocus will be rather loud, but for shooting macro photos, manual focus in manual mode is ideal. For the best results at 1x magnification, the lens should be stopped down and you should use a flash.
By stopping down you will get a greater depth of field, and using a flash will help keep the shutter speed fast. A 50mm is not that good for 1x magnification due to how little working distance you will have. At 1x magnification, the front of the lens will need to be approximately 2 inches 5 cm away from the subject.
This lens does an excellent job at copy work, close-up, and tabletop photography. It helps you to get closer to a subject than a standard 50mm, and that is ideal for nature photography when you need to fill the frame with a smaller sized subject, for example, a flower. The focus ring feels great when manually focusing, and the lens also has autofocus. Closed down at least a couple of stops and you'll get razor-sharp images.
Prices are constantly changing. During the previous several years, interest in film shooting has been growing.
Since there are Minolta 35mm cameras that use A-mount lenses, some additional demand is added to the price of lenses. The A-mount also does not have a significant share of the market. Due to this fact, there are fewer third party choices and the lenses manufactured by Sony are often on backorder. To get the least expensive price, check out prices on different sites. For pre-owned lenses, be ready to buy when you find a deal as they usually do not last long.
The Sony A55 uses the Sony A-mount. It's also identical to the Minolta A-mount. This is due to Sony buying Konica Minolta's camera division in Minolta created the A-mount for the release of interchangeable lens autofocus cameras in It is still Supported by Sony. Older Minolta lenses tend to have 49mm filter threads. There are many lenses that have filter threads bigger than 55mm. It isn't uncommon to see 77mm to 72mm. It would have been good if Sony made use of only 2 or 3 different filter thread sizes.
