You are right, the rear of the gadget lens is flat while the front is round. I already mounted

my lens on a cardboard, but it did not work, I think the reason is this lens is too far from the

ground glass.

Hello,

I already posted this question elsewhere, but I need help and I am under pressure...

I speak a bad english, hope this does not bother you.

I am trying to bulid a lens with a prism gadget lens I bought at Moma Store in NYC. It is a sort of multiple

diffraction lens, like a kaleidoscope. You see a bite of reality multiplied in several squares. The shape of

the lens is flat towards your eye and opposite is square patterned.

Well you need to put this lens very close to your eye (something about from 0.5 cm to 3 cm) to get the

effect. Well I would like to use this lens with a large format camera, so I need to build a lens with it.

The first think I did is to put my gadget just in front of a 150mm lens. Then in front of several lenses. And

in every case the image was soft and out of focus. So I started to unscrew my lenses using the rear or the

front elements together with my gadget. It did not worked either.

Is it possible to build a lens with this lens or it is just impossible?

Could you give me some suggestions?

Thank you very much,

Trent

Just a doubt: I have a 150mm Symmar on a Technika and I often unscrew it from the Linhof

lensboard and mount it on board of my 5x7 (with a 4x5 back of course). Will it cause any

problems to my lens?

Thank you

Me once I complained about scratches over my negatives and since then my lab put my

negatives in transparent envelopes and they print contacts directly from this envelopes,

without handlng them. No more scratches. But this is not what makes the difference, the

diffrence is made by the fact that my lab realised to touch my negatives very carefully.

Norm, I am not sure we are talking about the same object... I have several loupes but none

of them has foam or fabric, even oldest loupes are full metal and glass. Linhof did one

loupe (made in schneider), it was a 8x, no foam or velveteen.

Anyway I share with you your enthusiasm for LF!

Trent

Me too I have a Kardan and it is fantastic!

Welcome to the Large Format world!

My only suggestion is to get a good loupe, a 6x or 4x, they are my favourite

magnifications.

I had the same experience with my Lab. It came out that I am responsible even for their

faults: loss, damage.

Anyway I think that if there are black spots is your fault, I think that dust before

exposing the film leads to unexposed spots.

Hi Michel,

me too I posted a very similar thread just few weeks ago (http://www.photo.net/bboard/

q-and-a-fetch-msg?msg_id=00BQ0h)

It was about how to do it. Any further suggestion?

Bonjour

Trent

I just checked the Agfa website searching for infos about apx 100:

http://www.agfaphoto.com/en-GB/professional-photography/films/agfapan/agfapan-

apx-100-professional/index.html

There is a PDF file about the technical data of agfa professional films, I downloaded it, and

reading it I learned that 4x5 apx 100 film are still available. But then it came out that the

last update was made in July 2003...

Trent

I do not like to count, because make me feel nervous.

I trigger the shutter and shoot, trigger and shoot, trigger and shoot.

For the longest times there is no need to feel nervous.

Trent

Nice shot!

Do you think it is possible to do it also with color paper?

Trent

Hi Dean!

It is really very nice of you! Your instructions are so clear that I think I can sort it out by

myself. So there's no need to remove the rivets! Very good, thank you so much, Trent

Wow, thank you Todd!

I appreciate very much. How could I contact you to see if it is possible?

I am in big troubles because I have to replace the bellow of my Polaroid 110a camera. It is

a conversion made in Germany (I think) that I found in a second hand shop a couple of

years ago. Now the bellow is unbearable, this morning finally cracked. Now there is a big

open wound I can fix anymore. So I thought I can buy a cheap 110 or similar with a

good bellow and make a switch. But the bellow is fixed with rivets and here I stop and I

"cry for help".

Do you now how to replace 110 bellows?

Thank you ttw

thank you guys!

I know that Sinar stuff is super expensive but it is easier to find.

Anyway I will search eBay.

Thanks,

ttw

That's what I need! a new front standard... So it isn't possible to find it in Sinar's catalogue.

So I have to look for a original Horseman one? No chance?

Thanx tw

This is my first post.

I need some infos about l.f. I am quite new and I am organizing my studio.

There is a sinar model that is built just like my Horseman 450?

Rear and front standards compatibility, Lens boards, accessories...

Thank you
