|price paid:||SDD 1450 ( New )|
|positive:||Fast and sharp. |
Constant 2.8 good for the X center focus on some alpha body.
Focusing and zooming does not rotate it's filter is a real plus point.
9 blades. Nice Bokeh.
Good egonomics, good construction. No zoom creep.
Really positive as compare to the CZ lens of the same reach has to be the pricing.
Smooth zoom. Fast forcusing.
Great as a travel and protrait lens.
|negative:||The hood as compare to the CZ is not on par. But I am sure many can live with it.|
A tad not as sharp as the CZ 24-70 wide open ( F2.8 24mm ). Factoring in the pricing I can surely live with that.
Large filters required = $$$.
Have some flare issues but after removing the filter it disappears, must have been to the cheaper grade filters I installed. Have yet to purchase better quality to try.
|comment:||Sigma being a 3rd party lens manufacturer has really made leap and bounds on this lens for the alpha mount.|
Many mention about sigma and their bad quality control, I differ on this aspect. The copy I had was sharp on new and it never gave me front nor rear focus tingy.
Sure the price for this lens might have been on the high side comparing to sigmas from the past but quality wise is there. Taking into account of CZ lens pricing I say this lens is a real deal minus the T-coating on CZ lenses.
On C size sensor this lens is good even thou it becomes a 36-105mm. Which indoor shooting might not be wide enough but at that range it makes for a great travel lens.
On full frame this fellow really shines.
