Hi, I have a *1stDL with a K-7 on the way. I purchased few years back a 50mm F1.7 A manual focus lens. I can set the lens to A and the aperture control on the camera sets the aperture on the lens.
To my eyes this is a sharper lens than the kit 18-55 55-200 I bought.
But I am puzzled on focusing this lens. Maybe the Dl doesn't have the best VF or maybe it is how the lens focuses/depth of field. I know for example that at F1.7 and F2.0 there will be shallow depth of field but if I focus on the center point in the VF and shoot, usually at those apertures that focus point is not what is in focus so I have very few sharp shots.
I have tried the catch? focus technique using the AF mode on camera and turning the focus ring until the camera says, yep in focus, then takes the shot on it's own. Not as helpful as I thought.
I even tried both manual and catch while shooting in the woods waterfalls and such and didn't get many keepers.
Do you have any tips?
Here are 2 recent shots that were keepers and 1 from the day I bought the lens.
Thanks.
