It has served me well. I have just dropped and damaged it. To positively ID the lens: 1. This is a PopPhot test/review of the lens: http://i131.photobucket.com/albums/p295/solo_voyager/1-PopPhot.jpg 2. This is the lens end: http://i131.photobucket.com/albums/p295/solo_voyager/3-Lens.jpg 3. The side view of the lens: http://i131.photobucket.com/albums/p295/solo_voyager/2-Sigma28-7028AF.jpg 4. This shows the damage: http://i131.photobucket.com/albums/p295/solo_voyager/4-Damage.jpg I can see two possible ways to begin disassembly of the lens. 1. From the lens end with a spanner, or 2. From the bayonet end with a screw driver. Can anyone advise as to how to open this lens up enough to see and assess the damage, or possibly where to find a repair manual for it? Thx for any advice on this.
