Opinion of D FA 28-105 v D FA 24-70
I bought the 28-105mm and it serves very well.
Best regards, John
Having said all that, looking again at my first shots with the K1/28-105mm there are some pretty good ones so perhaps I am missing a trick.
I've recently been through the same process with the D FA*70-200 and D FA 70-210 and I'm more than happy with the slower aperture lens

UPDATE: I've pulled the trigger on a mint, boxed copy for under £300

I am only happy with f5.6 lenses if they are 400-500mm at the longest length and despair at the trend towards standard lenses (like the new Nikon Zs) having like a 16-50 f3.5-6.3....6.3 was bad enough on my Sigma 150-500 for light gathering and depth of field (too much even for a telephoto).

I'm interested to know the opinions of those of you who have owned both these lenses, particularly from the point of view of using as a "walkaround" or general use lens with a K1. Do you fell that the 24-70 is significantly better optically? How does the 28-105 perform wide open? Any other aspects that make one or the other a much better choice?
Thanks in advance

The 28-105 is a nice lens and in the optimum aperture range stands up against the 24-70 but the 24-70 is optically superb through the aperture range, Wide open it is superb and with a F2.8 is bright and clean.
In low light particularly indoors the 28-105 can be challenged optically and to use; I did a large event shoot over two days and found the 24-70 to be easy bright and pretty faultless.
But the difference in price doesn’t indicate a similar difference in IQ.
Without being unnecessarily pretentious;
In a nutshell the 28-105 is a very good lens but the 24-70 is a very good pro-lens that never seems to struggle and a joy to use

I'm not sure I could lug a 150-450 around for any length of time Mike - but I guess it's the type of subjects we shoot that dictate our choices

Forgive a noob resurrecting an oldish thread, but I have the same interest in opinions between the "little lens that could" and the "filthy beast." I have the 28-105 and like it, but have a line on a 24-70 at a price that is very very tempting.
Nothing much has changed from my point of view - I own both the 24-70 and 28-105, neither are in my "often used" category yet both are excellent lenses - the compact size and lower weight of the 28-105 means it is in the bag more often than the 24-70, in fact my 24-70 is so little used it is currently up for sale

My view of lenses is that if you can buy it for a fair price then do it! If it doesn't suit you the liklehood is that you can re-sell it for similar to what you paid - it's long been my mission to try as many Pentax lenses as I can (as some forum members will tell you
