I acquired this goal there are several months ago to save space during walks either in nature or in urban areas. It fulfilled its function of transtandard, namely not having to change constantly goal, but his qualities eventually stop there. Beyond 80mm, melted behind the subject looks more like a blur to move a fade. It also lacks sharpness. The maximum aperture of 3.5 at wide angle is really too limited when the light begins to fail a bit. Given the perspective of weight, the lock button to prevent the fu goes alone is a very good idea, but it is regrettable not to use it beyond 18mm (when one wants to make the manual focusing for example, must be the zoom ring to keep the focus, really not practical). The ring hangs past 135mm and feel is really not enjoyable. I conclude by adding that if you search the side practice this goal is because despite all the negative points I raised, the objective is decent for people wanting to make the reflex picture without having to pay 1 year salary. By cons, if you are a bit fussy, go your way because the practical side will ultimately swept by the many defects plaguing this goal (defects inherent in transtandards!) And you prefer to charge you a little more but be more pretty pictures.
