Hey there !
I'm kind of a newbie and I was hoping to find here an answer. I have an A80 and I'm trying to figure out how to calculate the focal lenght of its lens. I've searched on the net .. but found nothin really convincing. I would have to add that now I've purchased a wide lens along with 3 macro lens (+1, +2, +4). How does focal lenght modifies ? Thanks in advance. |

I don't know how to calculate/ evaluate the effect of additional lenses but... why do you need this ?
the focal lenght of a "naked" A80 is 7.8-24.3mm which in 35mm equivalent is 38– 114mm so... from here I guess you can insist on the net... http://www.navitar.com/zoom/cctv_how.htm http://www.navitar.com/buhl/conversi...culations.html |
