K-R and FA* 28-70 AL 2.8

I have sat on the DSLR sidelines way too long and am contemplating getting in with the K-r. I have a FA 50 1.4 and FA* 28-70 AL 2.8 from my prior film life.

(1) Does anyone have experience with a K-r and the FA* 28-70 AL 2.8? Good results? Can the K-r drive the power zoom? If so, does it hammer battery life and the number of photos per charge? As was the case with my ZX-5N, will the wide lens barrel obstruct the K-r's pop-up flash?

(2) Is there any reason for me to consider the K-r kit lens options, or should I just get a body and add a wide prime at some point? Any chance I would be satisfied with the kit 35 2.4 as a new normal lens, or will it be overshadowed by my existing lenses?

Thanks. If there were any brick and mortar stores stocking Pentax (Houston, TX), I would go try it for myself....

I can't speak for the K-r but I use the FA* 28-70 on my K-7 with terrific results. The power zoom works a treat and I have been surprised at the length of time I get from it before the battery wears down. I'm sure it would use a higher charge than normal zooms but I have not noticed it. I rarely use a flash so I can't comment from that point of view.

Hope that helps.

I've talked to Pentax technician, Power Zoom on the FA and FA* lenses are not suitable for modern day DSLRs.
Anyway, I've owned the 28-70/2.8, not a bad lens at all, pretty sharp

The lens barrel of my DA* 16-50 causes shadows with the pop-up flash depending on the zoom. Not sure how the dimensions compare.

Got away without using the flash for most of my indoor shots so far, but thinking about buying a proper one to get longer DOF when shooting candid family shots inside.

I'm in Houston and I own a K-r. If you'd like to get together sometime over the weekend and try it out first-hand, let me know. I don't know if you can get a feel for battery life, but you sure can check for shadows.

@abc,

Oops, got busy at work and failed to see your generous offer until this past week - after already ordering a K-R.

According to the manual, the combination of this lens with the pop-up flash will produce limited vignetting at 28 mm and a shooting distance of under 1 meter. For most applications it will not be an issue.

As expected, the power zoom does not function. And, it is a bit of a tight squeeze for my not very fat fingers to adjust the aperture ring. Might not be possible for someone with larger than average width fingers.

Power zoom works just fine with the K-7 and K-5. It is disabled on the K-x and K-r.

I used to have the FA*28-70 and the K-7 and now I have the FA*80-200 and a K-5.
