It seems short though the times you're getting can you give us more info on what kind of settings your camera is on?
If you finally come in the seconds, times are getting bigger faster so squezing your aperture 1 or 2 stops might already give you times of 8 seconds, I believe.

If you're going to stack ND filters you need to multiply them,
so ND4 and a ND8 would be a ND32.
The ND64 is a very heavy one so I would go for a ND4 or ND8 next to it.

Okay thank you, it seems very rare then.
I believe they don't even know it

I will try to see if I can buy it from them then and get it to fully working order and yes I'm going to keep it and use it then, only need some M42 lenses for it.
Only need to be carefull that they don't know how rare it is.

Thank you for correcting me clarky, I wasn't sure.
It surely is a special hood indeed

Kris, you know it's a good lens the FA31, see it as an investment. You know they will never drop in value those fine pieces of glass and alimilium. But first get a FA77, I've being told it's one of the finest lenses ever maded. You trully need to have one of those.

They told me that the material of the glass is mined in Hōrai by the people of Hōrai, do you know that they are small fairies and that they know no evil so their hearts never grow old. The raw material is then shipped to the Three Holy Mountains; Mount Fuji, Mount Tate and Mount Haku, where it get forged/molted. They used the wind of the legendary sword Kusanagi to cool the glass down. The lens is then assambled in Takamagahara so that only the greastest Kami is in the lens, which grands it such a good bokeh (bokeh isn't a Japanese word for nothing).
I know it's hard to believe but it's very true
All limiteds are made in such a way but they needed to bring down cost and they run low on great Kami so the DA are all done in Hōrai by the fairies, the FA are really splendid and trully worth it worth it.
It's a real honor to have them Kris so have I presude you?

What can you tell me about it.
I know it's the second pentaprism model and it only was in production for a year, so how rare are they?

At the photo club they have one that's still working fine except that the shuttertime is a bit off it seems.
I'm very tempted to roll some film through, just for the experience of it.
But if you say it's a rare piece of equiment, I think we should be a bit more carefull with it
I might even buy it then and give it some love

Kris, then the FA31 of course
The FA limiteds are a bit out of my reach so need to settle with the DA serrie

Kris, there is a DOF indicator on the DA* 55mm, on any prime lens from Pentax so far as I know.
It its harder to get a DOF indicator on a zoom lens since DOF is depended on the focal length you're on.
There are some zooms who has it but they won't fit in our image/design of the lens anymore.
I've looked up some zoom lenses and it seems only the A Series has a indicator on the lens.

I'm not attacking that locked is the wrong word for it, that's true. Only with your sentence 'the aperture mode will remain set until the shutter is released' you get the idea that you can't change a thing, that it is in Av/Tv mode instead of M mode untill you press the shutter release and that isn't true.

I would copy the magic latern book;
Tv shift - the camera will automatically change the shutter speed to provide corect exposure at the aperture you have set.
Av shift - the camera changes the aperture to provide a correct exposure at the set shutter speed.

I just looked the page up in the Dutch manual and they use the word lock for it as well, it just isn't right.

Good luck tomorrow with Amazon, I never had a problem with them.

Aviation is very different then any other brand I believe, the best doesn't always win but that's counts for every type of branch.
Do you know that KLM lease their aircrafts from KLM, I don't know why preciesly but it seems they are saving money by it.

The Tenerife air disaster never should have happen. Pilots aren't god anymore luckely, the mantenaince crew can overule the pilot now for example. But it's a shame that something most go wrong before things change.

It's good you're reading some books, it can get more complicated though
I'll be looking at your photos since I'm very interested in the DA* 55mm but also in the DA* 50-135, still not sure which on to get

I can tell you that the UV filter wouldn't do much, there is already an UV coating over the sensor. The only main reason why the use them is to protect the lens but they have quite strong coating these days so how usefull they are, is the question. You should get a polarizer though, they are very helpfull outdoors. They make the blue sky a more deeper blue and the from plants more vibrant.

Thank you Emily, that means a lot to me what you just said.
I'm going to try and improve it and see if I can do tha again to you

Prieni, That's very interesting.
I've readed it fast now because of the time but will read it better next time.
I'm thinking of quiting the study I'm doing now and do something in biology so what you're doing comes close to that.

Are those sensors also as accurate as lab results?
I can see that they can do the majority of readings but there must be some that are to critical, or am I wrong about that

Those look lovely Martin, they are both interesting acrss the fram, something that's hard to do.

If I really need to give some critque it has to be the flower in the second image, in the right lower corner. If you can get that out it would ask for so much attention so your eyes will flow better over the photo.
