Sigma 150mm f/2.8 EX DG OS HSM Macro

Pros: Build quality, sharpness, bright, quality / price ratio, apochromatic, AF very fast and accurate distances to the "normal" optical stabilizer.

Cons: bokeh not excellent.

Opinion: I use this lens a few months on Nikon D90 and although the car is not up to the lens, one is immediately struck by how sharp and the excellent color rendition. The weight is a bit 'increased from the previous version, but personally not a big problem. The objective belongs to the range of professional Sigma (EX) and is also discernible by the excellent build quality, coated metal. Very broad focusing ring which helps in difficult situations macro. With the lens hood comes with two mounted on each other if you use the lens on an APS-C sensor, but personally I've never had the need to install them both. The 'AF is the classic and tested Ultrasonic Motor (HSM) very fast, accurate and quiet, but has limitations in the case of macro photos really close distance (as well as many other lenses), better then set to manual. The picture quality is already very good at f/2.8 and vignetting is almost non-existent on my APS-C ... I had no way to test it on FF. Personally I find the quality of the blur (bokeh) is not excellent, but at the same time, this optical system has almost no chromatic aberration, so I would say that the symbol APO and fits perfectly ;-)

Nikon AF-S 50mm f/1.4 G

Pros: Standard focal length (FF sensor) luminossissima, excellent sharpness, AF silent, lightweight, great for portraits and still-life

Cons: A little 'soft when used wide open, fast autofocus.

Opinion: A lens that straddles the market for about 30 years, is considered the best optics "normal" house Nikon, this new model comes with the added SWM autofocus motor inside, it is therefore possible to use it in AF mode with the camera with no are equipped with a motor of their focus. (Es.D40 - D60) I always carry with me because it is very light and compact, I use it frequently for both photo reportage, both for portraits. Mounted on my Nikon D90 with APS-C sensor is a 75mm opening record. The best performances are obtained by working on the intermediate diaphragms, but it is really nice to use even at maximum aperture, where you create the blurred very delicate. Reading here and there on the internet seems to be ideal for the flagship of Nikon, the D3x.
