Question: Does this lens fit the DSLT Alpha 99 from Sony?
Document: All I can say is that after shooting many, many photos with this little guy, I've come to the conclusion that this is the easiest macro lens recommendation I could make for the alpha user. The image quality is surprisingly good, often bitingly sharp, with wonderful depth of field, and good color. In fact, when I reveiew the images, I can't make myself believe they came from a lens that is under $200. Way to go, Sony!The lens is also very light and compact. It is all-plastic construction.
The Sony SAL30M28 is a phenomenal lens. The 30mm fixed focal length is not the best for enlarging tiny objects but does an ok job at it. However, it is great for portraits. The specs say the minimum focus distance is about 5 inches but I've been able to focus on objects that are only 1 inch away from the lens. The 2.8 aperture is decent for low light, however the lens has a hard time focusing in low light. Either way, the photos it produces on a Sony Alpha A500 are awesome.
If you are really passionate about macro photography, especially about capturing small insets, you are likely to want to upgrade to a quieter and faster macro lens that lets you stay within a convenient working distance of your subjects. In that case, I'd suggest you to go straight to one of the other lenses such as theSony 50mm f/2.8 Macro Lens for Sony Alpha Digital SLR Cameraor theSigma 50mm f/2.8 EX DG Macro Lens for Canon SLR Cameras.If you just want to experiment with macro photography and don't want to spend too much for it, you'd enjoy using this lens.
wrong lens sent by mistake. There is nothing wrong with the lens per se, as all Sony products are excellent. It was not the one I ordered.
Sony products always delivers, highest quality lens you can buy. love my new lens! A great macro lens. Plan on using it a lot!
Mounted the lens immediately after I got it on my Sony A37 and was pleasantly surprised by the quality of the images and also as others have noted the DOF control, and clarity of the images. Not the fastest kids on the block but when shooting macros speed is not your major concern.Highly recommended.
I debated between this lens and the 35 f1.8. I decided to get the 30 f2.8 macro because it can be used as a normal lens with the field of view of a 45mm lens or it can be used to get close, only a few inches from your subject. The only negative is the lack of a lens hood. Sony doesn't make a lens hood for this lens so I ended up with a cheap ($4.50) metal wide angle lens hood from eBay which works very nicely.
The lens works well but is a little bit noisy. I don't know if that is my camera (Sony A300k), but the pictures are a little bit yellow and I need to fix that with some software. Is hard to get good pictures of subjects small than 5mm, and even 10mm is a problem to get the right focus. I think is a good lens for starting in the macro world, considering the low price against the other models (of course, than high price means better quality).
I do a lot of close-up flower photography so a nice macro lens is essential. I bought this when I bought my new Sony SLT-A65 and have loved the results. With a minimal focusing distance of just over 5 inches, you can get incredibly close for fantastic detail. Even my first images with this lens blew me away! Because of the closeness to your subject, keep a good clear filter on the lens (for me it keeps pollen off the lens). On top of all this, it's a great &#34;normal&#34; lens as well.
I recently purchased an A65 and wanted a nice fast lens. I was about to get the Sony 50mm f/1.8 but decided on this one instead. Reason being... f/2.8 is still pretty quick, 30mm vs 50mm, but primarily, it has macro capabilities. I must say I'm not disappointed!First off, this is a very easy to handle lens. I don't do much with manual focusing, but it's got a decent sized ring and a fairly short barrel. Very comfortable to hold and compose shots.
Answer: HI J.W., this is a DT lens for use on APS-C cameras only. Alpha 99 being a full frame camera, this lens won't work on the Alpha 99 as expected. Following is an extract from this lens's brochure:"Lenses marked "DT" (Digital Technology) should only be used on APS-C format cameras because their image circle isn't large enough to fully cover a 35mm full frame sensor. If you do use a DT lens on a full-frame camera, expect to see a darkening of the image towards the edges of the frame (vignetting). Although only E-mount lenses can be directly mounted on E-mount cameras, DT lenses can be mounted on these cameras via an optional adaptor."
