I usually set my focus at near infinity at F16 and shoot away. Zero AF lag
One advice to get even sharper pictures from the Zenitar: There's a clear filter on the rear of the lens. Don't remove it! It is part of the optical system - removing it will prevent your lens from focussing sharp at infinity.
The trick is to to unscrew that filter by a couple of turns - this way the filter is nearer the sensor and by some optical physics magic, you should be able to get VERY sharp pictures with this lens. The number of turns will depend on your copy of your lens. I have mine on 3 turns - it doesn't really jiggle around as there is still plenty of thread left, but I wouldn't advice more than 3 turns... .why? read on..
********* Disclaimer: by unscrewing the rear filter by a couple of turns, you are physically moving that filter closer and closer to the mirror box. If you turn it out too much, the MIRROR MIGHT HIT THE REAR FILTER (ala the protrusion of the EF-S lenses) and thus damage your camera. You should not try it too if you are using a full-frame or 1.3x crop camera, as the mirror is larger. I have tried it on my D30 and it works, but your mileage might vary. ***************
