There is a menu setting that needs changed.

I use a lot of old manual lenses from the 1970s through 1990s on my Nikon gear -- many are quite good (most old zooms however, are pretty poor). I always encourage people to experiment -- no pain no gain.

My K3 arrives Monday and I cant wait till I use my old lenses. The magic green button does wonders!

Since the bulk of my gear is legacy, I've been experimenting extensively with my K-series MF lenses on the K3 and find the metering and focus recognition (the focus censor knows when the focus is sharp at the selected focus point) significantly improved over my K-01 (granted, CDAF). I don't have a K5 so I can't comment on the improvement, but the K3 is very good.

I'm preparing an extensive post on the subject.

PREVIEW - reserving judgement for further experimentation, so I could change my mind: I suspect the same issues will exist, but not as severly; i.e there will be less need for Exposure Compensation to push or pull the sensor. Focus accuracy will be very good AFA generating the in-focus tone and hexagon. The viewfinder is excellent - judging focus at medium and small aperures is easy. I do not need my glasses, nor do I need a Correction Lens Adapter - first time in 15 years. Narrow DoF is still a challenge. Magnified LV with Focus Peaking is actually probably better for that - cool that is a one-button change. WB is much better. I suspect the new color AF module is helping a lot.

More later. If you bought it for the right things you'll love the camera.

I have a ton of legacy lenses and I'm looking forward to using the focus peaking feature and the faster auto focus for my DA, FA and F lenses. My K5 is a great camera but because of the focus, I miss a lot of shots. Live view is dependable, but I'm not always 100% sure I'm focused even at x8 magnification; the focus peaking feature mode sounds like a great feature.

hello,

since this thread is about older lenses i like to show some images taking with the K-3 in combination with the Pentax-F 1.7x AF Teleconverter with and the Pentax-M 85/2.0 and Pentax-M 200/4.0 old primes. the autofocus works well in this combination.

the images got taken on the graveyard cross the street of my flat and got just decent post processing with darktable (linux). some are high iso. i hope these will work as valid examples for the usage with old equipment in combination with the 1.7x TC.

greeting,

tx0h
