In addition to the 67 system and the 645 system, the 35mm lenses I have include:
F 24-50mm f/4
F 70-210mm f/4-5.6 (two)
F 35-70mm f/3.5-4.5
F 35-135mm f/3.5-4.5
A* 200mm Macro f/4
F* 300mm f/4.5 ED IF
A*400mm f/2.8 ED IF
Pentax 28mm f/2.5 SHIFT
Rear Converter A 2X-L
Rear Converter A 1.4X-L

It seems that if I can get top quality (think "coffee table" photo book) from 14.6 megapixels, I can fill in the super-wide gap in this lineup, get the K20D, and start.
The speed of the lenses doesn't change. You may find the K20D's excellent noise performance, and digital's amazing post-processing capability, allows you use higher ISO values, effectively giving you faster lenses.

There are plenty of pros who use digital cameras for book and magazine work. I don't think there's any concern about the resolution of the K20D, it's one of the highest resolution digitals available.

Have a look at what it would cost you to reproduce your Pentax collection with Nikon VR lenses. Staggering!

Since my first post kicking off this thread, I've spent dozens of hours online, reading about the Pentax DSLRs, various other brands (the Canon 5D MkII has my attention), and getting even more confused.

I feel like Rip Van Winkle.

For 30 years I shot photos for books, magazines, etc., mostly illustrating articles I wrote. Started with a Rolliflex TLR, went to the Spotmatic, and kept going. I know film.

While I have a Nikon D200, I use it almost like a P&S camera.

I have been mostly out of photography for 8-10 years. (Got into broadcasting.) Trying to catch up on the digital switch makes my head hurt.

Basic question: To get very good images for reproduction in magazines and books, will the 14.6 megapixel K20d be enough? I'm used to Kodachrome and Fujichrome.

As I contemplate launching back into some publication work (only the stuff that I think would be fun), I'm looking at the options.

I'll buy new gear, if necessary, but I know the Pentax lenses I have are very good. Just did an inventory today. Sheesh. It's amazing what you accumulate over the years.

In addition to the 67 system and the 645 system, the 35mm lenses I have include:
F 24-50mm f/4
F 70-210mm f/4-5.6 (two)
F 35-70mm f/3.5-4.5
F 35-135mm f/3.5-4.5
A* 200mm Macro f/4
F* 300mm f/4.5 ED IF
A*400mm f/2.8 ED IF
Pentax 28mm f/2.5 SHIFT
Rear Converter A 2X-L
Rear Converter A 1.4X-L

It seems that if I can get top quality (think "coffee table" photo book) from 14.6 megapixels, I can fill in the super-wide gap in this lineup, get the K20D, and start.

If not, I can sell this gear (plus the bodies and all the accessories), to finance part of the new system.

Second question (I think I know this one). Unlike a converter, the extra "length" you get on a lens when shooting with the smaller sensor does not come with a loss in speed, right? That is, my 300mm f/4.5 stays an f/4.5, even though it now functions as a 450mm lens (in 35mm terms) on the K20D.

So, can someone help old "Rip" out here?

Thanks.
George Lepp posted an article in one magazine that I have since passed on to another - Outdoor Photography? - in which he pointed out that he had done magazine covers with 6 Mp. A reasonably well exposed 14.6 Mb image should print very nicely at 24x36 inches, and perhaps more.

The "extra length" is simply an image crop that you cannot avoid. It cost me a bit of cash to get wider than 24mm equivalent when I bought my d10d. Bummer. All the lenses I have kept (all except the DA ones) still work reasonably well on the k10d. The two M lenses do need manual exposure to work properly, but I can only use manual exposure. Looking at your equipment list, you will lose no functionality with any of the lenses, except for the shift lens, which will only work in manual exposure mode unless it is wide open. Even then there are two methods of rapidly metering for the manual exposure, the easiest being to press the green button near the shutter release to set the camera's metered shutter speed. I prefer to use the exposure scale, obtained by using the dof preview on the shutter switch which is only available when you set it for viewfinder dof preview.

the jpg raw debate is easily solved, shoot raw+jpg for a few days(or months) and make your decision.

I had posted a note that I was going to sell the Pentax 35mm stuff.

Thought about it all weekend. Changed my mind.

Just ordered a K20D.

It'll arrive at the same time as the D700.

Just couldn't bear to part with all those great Pentax lenses.
