AstrHori 28mm F13 2X マイクロプローブ フルフレームレンズ

Sin duda este producto vale la pena por el dinero, tomando en consideración de que la competencia de este tipo de producto cuesta el doble. El ahorro de la mitad de dinero no se relaciona a que estás obteniendo un producto de la mitad de calidad. La calidad es practicamente la misma.

If your'e looking for a general- purpose macro lens, this isn't it. But if you're after a specialty lens that captures 2:1 macro images, has an integrated light, and is submersible, this should do the trick. Image quality is quite good, especially at mid apertures. It's the sort of lens that requires planning and setting shots up carefully. But patience and planning are rewarded with shots that other types of lenses just can't capture.Operation is smooth. It's a fully manual lens, so aperture and focus are both done by hand. For extreme close-ups, focus depth of field is very shallow even at the small apertures the lens accommodates. But it focuses easily and accurately. At longer distances (past several inches), depth of field obviates focusing issues.I gave it four stars because it's definitely a niche lens that many photographers/videographers could easily do without. Definitely not a must-have. But if you are looking for something to spur your creativity and you have the patience to plan and execute shots carefully and thoughtfully, you might really like this oddball lens. I do.
