HI

I on the other hand love extreme wide angles zoom lenses and i am quite disappointed with the availability of them for Digital
Most zoom lenses have become 'normal' wide angle and only some (if not only one the 14 mm which becomes 21 in reality) is available which is a fix focal length

Not sure how and when they are gone come with wide angle zoom lenses but i certainly can't wait

Once again i express my anger at the APS size sensor

Thanks john
You are right the pics come out alright, but i just can't get over this little technicality

HI

Interesting theory of the DOF

Now i just got ahold of an old pentax SuperA, and to my (not) surprice i could not get the Peleng to focus, THe Super A has one of those old focus systems with the circle and a middle line, and i can not get the lines straight in the middle..

What could i be doing wrong if any? Could it be the m42 screw that it is too long? help!

HI

Yeah i was not asking how to meter it, just if the aperture set of the lens made any difference as it apparently does (from what i read on another post) also each time i read about it there are small facts which are forgotten

The explanation of the focusing would not explain why it does not focus objects at close range (or give the signal)

Any how it would be handy if some one had the lens, as I also seem to get a white foreground when used with a flash ??

Thanks anyway

Hi

I have a Peleng 8mm with a M42 adapter, now the lens is fully manual which is not much of a problem , how ever one thing I noticed is that the focus indicator does not work with this lens attached, and I am wondering If this has to do with the M42 adapter; could it be that the adapter is just a mm too long? Are there different M42 adapters? ( I saw that Steve in another forum called it M42-PK)

Also another question; to be able to use the green button, i have read that apart from being in M mode, the aperture should be wide open, so at f/3.5 with the Peleng, this is a shame cuz as we all know the all around sharpness decreases.. so does it have to be at f/3.5 or could i use it at f/17?

All this said I have managed to take good pictures with it but would like to know the correct way as to not waste opportunities

Thanks

Hi guys

Thanks for your reactions and explanations
Yeah i am not that worked up about it, I must learn to use my Zen techniques when dealing with all this changes

No but on a more serious tip, I think it is all a scam for companies to be able to sell new lenses and equipment, the price of the CCD and the light weight of the lenses is just the excuses they use

Anyway thanks

I have a question for you all, the lens mentioned states that it is a 16-45mm, and i was wondering if used on the istD I would have to calculate the 1.5 factor or would it stay real 16-45mm
I ask because the info i have found confuses me, it states, i quote:
"The compact, high-performance, interchangeable smc PENTAX-DA 16mm-45mm F4 ED AL lens features a 3X zoom ratio with focal lengths covering ultra-wide to moderate-telephoto ranges for the angle of view equivalent to 24.5mm-69mm in the35mm format."

Could some one help me with the answer?
Pano

Thanks all

it is nice to get some reassurance from experianced users

cheers
