I have the 19AH verssion, the Pentax forum say it's the best 70-210 ever, surely there have been others since the 19AH was discontinued in 1999. I've since got a Minolta 70-210 f2.8.

I keep meaning to take a picture of my smallest and longest lenses next to each other but always forget. Maybe at the weekend.

It's not really weird, but it is germane to the thread - this is my Mum's old Adaptall 2 lens (I don't suppose she ever used it - she wanted to take photos, but never had the time to actually work out how) on my D200. I'm going to have to remember the set-up should I want to send anyone an unsolicited dick pic, as the angle and the phone camera make it look longer and thicker than it actually is! ron 80-210mm by gray1720, on Flickr on Flickr Is that the 103A version? I have 2 of those (my Dad, brother & I all had one in film days). I always thought of it as a respectable (but not stellar) performer. Tamron made a surprising number of adaptall variants in 70-210 or 80-210 ranges there's 03A, 103A, 158A, 19AH, 46A, 47A, 52A, 58A as well as the odd 85-210, & 70-220... You can add 70-210mm f/3.8- 4 to 22 version 46A to the list, I have just found one sorting through some kit. |

I have never seen a Q dwarf a lens before!  Really really wish Pentax launched a so-called 1" sensor Q with a similar range of lenses to before, that would be 99% of what I want/need as a daily camera. Well, 90%. Ish. I wish someone sold CS adapters for the Pentax Q, that would allow some lenses that are even smaller - I believe 3D printed adapters for CS have been made, but I'm not going to get into 3D printing. If you want a CS to Pentax Q , contact these guys . www.srb-photographic.co.uk/specials-1065-c.aspNo idea how much they charge , but they'll make one fopr you no problem , and out of metal , not plastic . |

A couple of weird options for my 5x4 monorail  A challenging lens by Mike Kanssen, on Flickr  delta 77 - GG removed by Mike Kanssen, on Flickr Both likely to be TV projector lenses, the first is roughly 150mm f/1.2, I've not yet determined the focal length of the second it gives very roughly a 120degree FOV & needs to be mounted VERY close to the ground glass (almost touching at infinity focus, as shown by the shot above with the ground glass removed) It is also fairly fast.  delta 77 - deluxe & GG by Mike Kanssen, on Flickr |

I imagine that is a wide ish aperture lens with no iris so a lens cap as a shutter will be too long an exposure for anything other than a paper negative. |

Even indoors with direct positive paper (~ISO3) it's proved a challenge. My best analogue result so far has been with a paper aperture to reduce a couple of stops & a Galli shutter (two dark slides) One suggestion I've received is to use a ND gel, and another option is just to shoot in the dark with a flash  The easier option I've used so far is just to use digital to shoot the ground glass, but shooting square on seems to exaggerate vignetting. A large format meet up I'm attending in April will hopefully give some other options - both of these lenses are far too big for my Thornton Pickard shutters. |

A guillotine or falling slot shutter may be an option, I did think about them years ago but had no way of making one so got distracted by press cameras with focal plane shutters which was another rabbit hole and I lost interest. I suppose these days, one could be 3D printed. Goes off to look at thingiverse... |

There is a leaf shutter on printables for which I have downloaded the STL file, it claims to part of a 10x 8 camera project. I will have a look at the dimensions and report back.

I have been planning to try making one, but I haven't got round to it yet, My PhD in procrastination is holding me back. It is about 70mm diameter on the front lens mount which looks way too small for that lens. I might print off the parts and assemble it just because it will fit the Lancaster full plate enlarging lens I have here. |

If I made one I'd want to be able to use it on my biggest lens (the top one, which is even wider than the delta77) - going up to a 6" diameter. I've not found stock solutions anywhere near this size. |

I will add it to my rainy day something to do list, there are quit a few parts to print so it might take a while. |
