    hi everyone,

    so i got a sony alpha a5000 the other day after reading a lot of reviews of entry-level cameras at that price. it's quite cheap now since the a5100 came, i guess. it came with a kit lens. 16-50. i hardly used the lens at all because it can't be much good, from what i have read. i am used to a 50mm 1.8 on my nikon dslr. i guess image quality can not equal that in terms of sharpness from a micro four thirds camera but at least i can move closer to it. :)

    what good value lenses would you recommend? i mostly want to do street photography and also since it is a crop body, i need to think about that. maybe this leads to the question, what is the best lens for street photography.
    so far i have read very good things about the Sigma 30mm 2.8 dn art. There is also a 19mm version.

    thanks for any tips and advice

    Is your Nikon full frame or crop? If crop, then it has the same crop factor as the Sony and you'll want something in the same focal lengths you already like.

    I shoot a lot of Street. Any lens can be used for Street, as lenses get longer and wider you have to stretch your imagination in order to accommodate longer and wider lenses. Most Street shooters use lenses in the Full Frame focal lengths in and about - 30mm to 40mm range, give or take 5mm. In APS-C format, this would mean 20mm to 28mm. As you are new to photography and Street, I suggest in-between the two lenses you suggested. The 30mm may be a bit too long and you'll be frustrated that you're a bit too close to fully capture what you see and the 19mm may be a bit too wide and you're a bit too far away to fill the frame. But between the two you suggested go with the 19mm and crop in post.

    I would go for a 17mm 1.8 or a 24 1.8

    They'll probably give you the better shots for street photography - allowing you to be discreet, too!

    Forget that (though a different word starting with the letter f is better suited here).
    Have you actually tried using the lens? What do you think about the results—are they good enough?

    I have decided to get the Sigma 30mm 2.8 which I believe will be 45mm on my a5000. Since the cropping does not change angle of view, if I got a 19mm, every shot would be very distorted. I feel it might be too specialist(?) Although I enjoy using very wide angles sometimes for vista shots, I think on the street and out and about around the city, a more 'normal' focal length might be in order. What I really want is a 35mm but 45mm for now.

    Great center resolution on that lens, but utter RUBBISH performance at the edges of the image, at all apertures....the 50% drop in edge performance vs the center is gonna' be noticeable I would think...this is a horrible differential! I do not think I have ever seen such a substantial center/edge difference as this Sigma shows in their test result graphs.

    What do you mean? That's basically the only thing that the crop factor directly affects!
    Forget about crop factors, as you're only using one sensor format: APS-C. Have you had a chance to actually use the 16-50mm you already have? If so, you should be familiar with its focal lengths, and know what to expect from each focal length. Or, perhaps, you should use it a bit to become familiar with the focal lengths, and see which one you like best.
