I think you will find that lenses that start at 50mm or higher, and then go very long, are generally better because most of the compromises come at the wide end. Many serious film photographers who were into wide angle images went to Leica in years gone by because the rangefinder wide angle lenses were not as optically compromised as the SLR lenses. This is because the rear element ofa good wide angle needs to be close to the film plane (some ultra wide SLR lenses actually mounted only after mirror lock up because they extended too far into the body to fit otherwise). SLR wides use a "retrofocus" design to allow for the distance from the film plane, perfectionists argued that this compromise degraded image quality (if you were making posters I guess). Since Zooms that range from less than 35mm to more than 100mm must go from retrofocus wide design to normal range, they have more compromises than a lens that stays above 45mm for its entire range.

Any techies out there who can relate the real details,please do.

Thanks for the info, I kind of like the idea of a 500mm lens and the 50 - 500 might be the ticket.

I would dearly love a 500mm f4 prime, but at the moment can't justify the expense.

It looks like I will be spending some time down it the Solomon Islands this year and will be planning a lot of photo/strolls about the place.

There is a fair a mount of WWII relics about and being a bit of a war buff, hope to find some of these, especially any planes in the jungle.

If their is a need for a 500mm Prime after my fist trip, I might buy one, but in the interim I think I will get the 50-500mm Sigma, it is not too big and I think I will have just superceded my new 70-300mm sigma :O:O with that sentence.:G

Apparently I may end up there for 2 years, I would like to think I can do 12 months only before I get some other exotic locale to work in.

Guadalcanal was quite a busy battle area during the war and I have been told that there is a fair amount of things to see.

All things being equal I should be there by June.

Of course I will be posting images as and when I can get access to the web to show off this exotic group of islands and my awesome photographic skills :G

Received the lens, very happy with the condition, attached is a 100% crop from a flash picture taken at 300mm. This is a little soft but retains a lot of detail, the print from the full frame isquite decent. Manual focusing this lens is much easier than the Takumar-F because of the much larger focus ring, the zoom works very smoothly but does creep a little however, but not enough to be a problem.The lens mount is plastic but much higher quality then some mounts I have seen from other manufacturers.

In spite of some less than stellar reviews I find this lens quite acceptable. The six blade aperture does not produce the nice out-of-focus highlights that the Takumar-F does, and the plastic mount does not seem as substantial as a shiny metal one, but the overall design is very user friendly with a very nicely usable focus ring.


Anyway, I have tried this lens in several different ways now with great success, I will post more pics when I get something worth posting.

Here is my present Pentax camera body collection (missing is an MZ-7 with AA battery pack and of course the *istDL). Before anyone comments, no there was not a motor drive K1000. That particular camera has a broken shutter so I was playing around with a box of old parts someone gave me and found an old Spotmatic motor drive. When I removed a few parts the two would fit together. The 28mm was in the box as well, shame, badly scratched rear element, so that particular combination is now a bookcase display piece in my living room.

The other K1000 and the KX are both in working order. I also owned an ME Super that I sold about two years ago. I loved these cameras, and the DL seems to be the the closest to what they represented, namely a camera that is not the "best" at anything (except maybe size and price) but is very good at everything.

Here is the 100-300mm mounted on my DL, with the 28-80mm included for comparison. I have been a user of "cap-keepers" for years, you can see one on the 28-80mm, now I need two more for the 100-300mm and the 18-55. At first I was a little paused by the silver finish but it does grow on you, especially with the silver finish DL. It may not have the cache of a white Canon L series zoom (yes we have all seen their magazine ads, a bit much if you ask me), but it is distinctively Pentax.

Crashman, I have a cheap 500mm f8 mirror lens, not great, but in good light it is surprisingly good. It will be a few years before I can really justify the expense of high-end glass. It is too bad that the selection of f4 zooms isn't greater. In the MF days Pentax sold some reasonably prices 70/80-200/210mm f4 lenses, now it is either a rather slow variable aperture model, typically f4-5.6, or a very expensive f2.8 monster which costs in backache almost as much as it does in cash. I have35-70mm f4 and70-210mm f4 Minolta Maxxum zooms that are excellent, wish I could get equivalent lenses from Pentax at a better price.

So I will soldier on with what I now have, the only LBA attack I am likely to have now would have to include an F or FA 50mm (probably the f1.7 which is more affordable)

Ira

BTW Crashman, enjoy your work tour and get some pictures posted whenever you can.

Looking at two nice 28-70 f2.8 on ebay at the moment. I have found two versions of the same lens.

A 67mm filter Aspherical DFand a 77mm filter Aspherical DG, they have similar lenses and groups, the 67mm (might be a 62mm, can't recall just right now) is obviously the older model, but both are new lenses.



Might buy as an interim LBA hit......:evil:
