upgrade to a K5 or a faster zoom lens?

I am sure there are many people already upgraded from a K7 to K5, so this questions should be easy...

I am currently using a K7 and finding the low light performance below average.
With limited budget, I am considering weather to put my money on an upgrade between: (a) upgrade to K5; (b) a decent 70-200mm F2.8.
Upgrading to a K5 seems to be a quick solution, but a decent set of glass may work on the K7 as well.

Any suggestions?

Many thanks

Bodies come and go, but glass is forever?

Agree with Euology.

I have a K-7 and I invested in good glass: in my case, nice primes (CZ, VL, FA*). The result is well worth it and each lens is a true investment.

Like many K-7 users, I acknowledge the low-light limitations of the K-7. Some fast primes enhance greatly the situations. I shot several times at sunset with my K-7 and VL58mm f1.4. There were other Canikons and I was always the last person to shot, sometimes 45 min. after the Canikon users left!!!! I did not check their lenses and assumed that most had a kit lens, except in one case when a Nikon user had a f2.8 lens (and he stopped to shoot way befor me)....

Food for thoughts...

A fast 70-200 will add approx. 1kg to your kit weight (and a lot of bulk) over a slower tele zoom like the 55-300. If that's a factor, the K-5 might be a better solution.

I had to make this kind of choice myself and after I handled the Sigma 70-200 I realised that even if I bought it I'd be leaving the damn thing at home more often than not.

Great lenses for a specific use, hardly general-purpose.

In the 70-200 zoom range, 2.8 is about as good as it's every likely to get without getting stupidly large and expensive.
New and better bodies are going to keep happening all the time, and the K-5 is due for an upgrade soon.

So get the lens

K7 had known issues with low light performance when it was released. K5 had (and still has) no issues. In five years time your K7 will be just as unsatisfying as it is now, while a K5 will be just as good.

I recently upgraded a Kr. I thought about saving a bit of money and going for a K7 (perhaps a move sideways rather than up), but on the principle of buy right or buy twice I went for the one I'd really wanted all along: a K5. I don't anticipate buying another body for five years or so.

I'd say go for the new body. It'll serve you well.

Go for a good prime.
Save the change for the upgrade when it is available!

Thanks guys.

To make the picture more complete, I normally carry my K7 with three lenses: Tamron 17-50mm F2.8, FA 50mm F1.4, and Vivitar 70-210mm F2.8-4.0.
The Tamron 17-55mm covers most of my daily usage and the FA 50mm gives me a good choice of bokeh when shooting stills and portraits. I suppose the logical thing to do next is to replace the Vivitar, because it is slower and softer. At 210mm F4.0, the K7 is very challenging to shoot with, giving me extremely soft images. Stopped down, it is harder to shoot without a tripod or increasing the ISO. The choice is between:
1) Shooting with K5 at higher ISO at F 5.6 (get a new body?)
2) Shooting with K7 at lower ISO at F 2.8 (get a new lens?)

I suppose the right question to ask is: how good is the low light performance of K5? is it better than the pictures taken with K7 with a fast lens?

Data points:

* Ain't no zooms faster than f/2.8
* Long f/2.8 zooms are costly and heavy
* Good glass lasts forever; bad cams suck forever

My recommendation: Get the K5, and some fast manual primes.

You'll also get an extra 3.5 stops of dynamic range from the K-5. With all your lenses.

For low light shooting the k5 will make a difference. Maybe getting a monopod would help with stability as well.
