The Q1 has been built:

150mm f1.3

Looks pretty good on the speed graphic (not attached so not 100% perfect)
...

There are screwthreads all the way down the barrel but I didn't see any scratch marks for any lens being fitted like that so it could be something that would attach to a telescope etc

I am tempted to adding a wooden handle to the screw threads and add a nice lens to it, doubt its worth much in its current condition/configuration, would be cool to know what it originally was...

There are no additional controls, its basically a box with a shutter on the front and ground glass on the rear, someone else on another forum has suggested something like a microscope camera or maybe...

Hi all,

I just got this camera yesterday, I took a gamble on it and won it, its got a working Luc shutter but says Zeiss Ikon on the back and has a 2" lens barrel (no lens unfortunately!)
...

Older 127 camera:

Shutter blade on top moves down on the press of the button putting tension on the spring connecting the 2

Newer 127 camera:

At rest:

Cocked - copper coloured trianular piece flicks the end of the shutter blade
...

Ok, I have taken delivery of a few older cameras from something I won on ebay - I was just bidding as there was a Purma special and I wanted a spare one lol there were 2 127 box brownies with 2...

I will be using waterhouse stops in the centre, I would need to have the shutter cover the whole diameter of the lens though so it would be the same size where ever I put it.

You could always use the bent lens ring repair tool?

The front and rear elements are the same size, optical element diameters are either 110mm or 80mm (the 2 different lenses I am building), with the 80mm element lens the focal length will be at around...

I have just taken apart the front of one of my project plastic cameras (Vivitar PN2011) to look at the simple shutter arrangement.

It is basically a pivoted flap where a spring loaded notch is...

I would need a faster shutter speed rather than a slower one, I don't want to stop the lens down too much as I would be wanting to get some bokeh with portraits, I guess I could shoot in subdued...

The front element on the lens is over 4", which is why I will have to go with a DIY option, plus the camera is a 'cheap and cheerful' trial to see how cheaply you can make a 5x4 camera and lens.
...

Thanks for that, I think using an ND filter for a longer exposure for landscape should be good, however I think I would still want to shoot it wide open and would need a fast shutter speed for...

Thanks Tim, yeah I saw the guillotine shutter, its quite simple and you can adjust the shutter speed depending on the slot gap, however it would also need to be 3 times the width of the lens which in...

Hi all,

I am currently in the process of building a 5x4 camera and my own lens, everything is going well except I will be in need of a shutter, due to the f number on the lenses I am building even...

Thanks IanG, I currently have a Schnider lens on the speed graphic - I have yet to shoot on large format due to needing to sort out developing the film myself - but am looking forward to seeing what...

Yeah thats what I thought, its obviously a lens between the standard set we have today, but not the same as the older lenses which started at f1024 for f3.2 and halfed the number each stop lol I...

Thanks for that, I know that there was a London factory, but was closed before the war - German products weren't really wanted at that time!

Got the info from here and the lens number checks out...

Hi all,

I now have a nice Carl Zeiss London Tessar lens, the number on it dates it to 1913 which is cool, I will be mounting it to a pacemaker speed graphic so the fact it doesn't have a shutter...

I was about to post up LF lenses are 3x focal length compared to a 35mm camera for a 5x4, so a 'normal' is 150 etc, if shooting on a 5x4 look at something around the 90mm range. Although i've not yet...

Right, this is all sorted now, the seller sent me over the details on how to reset the switch - its very simple to do, basically remove the and then loosen the cover to allow the slider to move...

Hi all,

I have just got myself a nice Pacemaker speed graphics, its got a Kelart rangefinder so i'm guessing its pre 1955, thing is the slider for the shutters doesn't have a marking on them to...

Its ok, im going to keep this setup for a while, I know I can't go super wide with this camera but thats fine, its slightly wider than the normal 150mm so thats good enough for me, this will be a...

Thanks Darin, the guy I am getting it off has been restoring Pacemaker speed graphic and crown graphics for about 10 years, I might be tempted to get myself a rollfilm back at some point as well...

I have gone with a 135mm lens, I have actually gone with a Pacemaker speed graphic camera 5x4 size which has been fully restored and CLAed and its running a 135mm Schneider Kreuznach f4.7 lens, also...

Hmmm tempting! I did have a look at the V700, it would have been my first choice if it wasn't so expensive, although I might just stay with 5x4s and 8x10 is massive lol

Thanks for your comment, I will defiantly look out for convertible lenses when I do start buying kit, I thought that all LF lenses were primes which is why some LF bags are large to allow for a wide...

Lol, im in the UK so might have an issue with shipping it over etc, im going to hold off buying the more expensive items (like lenses and tripods) for a bit, im not in a position to buy at the...

Thanls for your comments Jim, im going to be taking my time over this, the tripod will indeed be a fair investment but will be useful for all the cameras I have so I will be spending a bit of cash on...

Its why I don't have any kit at the moment lol im researching into LF, I will have a look out for those books, I won't be buying anything for a while as I want to get it right first time :) I wanted...

Yeah I could create a digital negative, I have heard of waxing paper to make it transparent I guess I could just use Cyanotype as the printing process instead of going hybrid on some shots, it seems...

Thanks Len,

The online used camera shop I normally use is 'Rocky cameras' as I am in the UK, they have all sorts of lenses, cameras and accessories, will be grabbing some accessories from there...

Thanks for your help on this, I came in via the forum so I missed the homepage lol I will check it out :) that seem pretty reasonable for a lens considering these were built to last unlike these more...

Hi all,

I am getting into large format and will gradually purchasing the components over time to be able to build up a large format kit, im going with a 5x4 setup so that I can keep the cost down...

Hmm thats true, it would need to have a lens on it then otherwise the exposure would probably be days lol :D its something that I will probably try at some point but I know that LF lenses aren't...

The guy in the video just developed the cyanotype images from the camera as per usual though? I will check out retina prints, it will probably be quite a while before I get a large format camera kit...

Thanks for the welcome Andrew, I will look into it, I have been looking at other processes but like the simplicity of just having 2 dilute chemicals in the whole process and not needing to do...

Thanks for your response john, yeah I was thinking about using photographic paper but then I would need a lot of developers etc to process it, whereas with Cyanotype you can just use water (and a bit...
