Included are the lens, the hood (it is worn and old but still does the job) and a soften filter. This is known as the 'secret handshake' lens.
People are using these lenses on Sony Alpha cameras, they fit in directly with the A mount type Sony Alpha's. It turns out that Sony bought out the Minolta camera division and high end Minolta lenses are a great choice for the Alpha's.

Maxxum 28-135mm f/4-4.5: Legendary Standard Zoom by Minolta
The Minolta Maxxum 28-135mm f/4-4.5 is one of the few elite lenses manufactured by Minolta that remain within reach of the average Minolta photo enthusiast. On par optically with the G series lenses, it isn't a cheap lens but is certainly an excellent value. Like anything else in life, you get what you pay for!
The story on this lens is that it was manufactured at the same Japanese (Sakai) factory that Minolta built their APO and specialty lenses when the Maxxum line up was first introduced in 1986. Long since discontinued, at the time of its introduction it was the worlds' first rear internal focus lens. The lens is a beauty, both optically and in a physical sense. I am totally hooked on this lens and use it as my primary "go to" lens when I am outdoors. This is one of those classic Minolta lenses that prove the company knew how to make great (and innovative) glass back in the day. The three photos above were taken within an hour of each other, so you can see how versatile this lens is. For these and more (hi-res) examples of photos taken with this lens, check out my gallery at flickrdotcom/photos/seagr112
For covering such a wide focal range, the lens is near flawless in its image reproduction. It is sharp, sharp, sharp, from wide open to stopped down. The 1st generation vintage build is solid and substantial. All metal, inside and out, and beautiful glass. Attached to my 7D/VC-7D, it is impressive and quite a handful - but it works. And it minimizes lens changes with its wide focal range. It is absolutely perfect as a travel lens and for working outdoors.

What do these numbers mean? The higher the scores, the better the contrast and resolution of the lens. A 3.6 grade is extremely good for a zoom lens. A grade above 4 is only seen in dedicated Macro lenses, the finest primes and some G series lenses. No other Minolta zooms compare to the 28-135.
