Sigma 45mm f/2.8 DG DN Contemporary Lens (L Mount)

I am a professional fine art Nature photographer who is used to carrying substantial equipment in my backpack. But, sometimes, I really enjoy traveling light. I have only had this lens for a week. But, I am already impressed. For landscapes, Its field of view is slightly larger than for a 50mm lens but still avoids the over-emphasis of foreground objects associated with wide angle lenses. It is light and compact, but all metal and really well designed and constructed.Importantly, its superior image quality puts it in the top class of normal lenses. In the photographs that I've taken so far, there is almost no significant difference in sharpness and contrast between the edges and corners compared with the center when stopped down to the optimum aperture of f5.6. ... MoreI am a professional fine art Nature photographer who is used to carrying substantial equipment in my backpack.

It is light and compact, but all metal and really well designed and constructed.Importantly, its superior image quality puts it in the top class of normal lenses. In the photographs that I've taken so far, there is almost no significant difference in sharpness and contrast between the edges and corners compared with the center when stopped down to the optimum aperture of f5.6. And for apertures between f4.0 and f8.0, its overall image quality is as good as the best Sony GM lenses, except for the new 135mm f1.8 GM lens. Its versatility is highly welcome. It focuses more closely (9.45) than most normal lenses; and I like the way that it works with my Sony A7rM4 where I have the option of using a C-size image of 28MP making the 45mm lens an effective 68mm lens, thereby enhancing its close-up ability.This lens is a great choice for street photography, landscapes, close-ups, portraits, and even some wildlife subjects, and when used with a compact mirrorless camera, it's small size and low weight makes it effortless to carry it with you in any environment.The attached images were made at f5.6.

Some reviewers have commented how this lens is soft when close to a subject. Even though this lens claims to have a short focus distance, I don't believe that this is what that lens is made for. When focusing at subjects that are more distant, this lens is very sharp and offers a lot of detail. I used this lens on a Panasonic S5 and it works flawlessly. It is quick to focus and provides great results.The lens has an aperture ring on it. So, if you're coming from a Fuji system, you'll feel right at home. If you prefer to adjust the aperture setting from the camera, you can do that too.This lens is versatile, unique, and a lot of fun to use. What makes it great is that it isn't your typical nifty fifty. It has character.

I had this lens once before and used it with my original Leica SL. Sold the SL and sold this lens.Bought an SL2 and bought this lens again.While this lens was excellent on the 24MP SL, on the 47MP SL2 this lens is noticeably soft from wide open up through f9. If you need a near 50mm slowish lens and you don't mind that it is a little soft, I recommend this lens. Well built and easy to operate.
