That's one I'm considering picking up for the Q. It looks promising. Are there any of the Industars I should steer clear of? Will the M39 Industars work on the Q with an adapter? (One seller says the M39 won't work on a MILC, but doesn't mention the Q specifically.)
The Industar 50 was manufactured for decades and can range in quality by quite a bit. the pancake version for the Zenit SLR is the most common (beware, there are both M39 and M42 versions for SLRs) . This same SLR lens was fitted with an extension tube for use with M39 Zorki or Fed Rangefinders. if they're from the Zenit, you'll need to use an M42 adapter (and if it's a Zenit M39 version, a M42-M39 reducing ring), and if for the rangefinders, the M39 adapter. I have no experience with the Collapsible version, but it should use the standard M39 adapter.

if you're looking for the higher quality copies from the 50s or 60s, it's best to look for the "Red P" versions - these have a red Russian P ( П ) on the front of the lens.

Or look for the Industar 50-2, which was manufactured in the 70s through the 80s if I remember correctly. better image quality and coatings.

this is an Industar 50-2 for SLR cameras. it uses the M42 adapter:

New Industar 50 2 3 5 50 Russian Lens M42 Pentax Canon Sony Olimpus Lumix 043325446412 | eBay

this is an Industar 50-2 for rangefinder cameras - it has the integrated extension tube. use an M39 adapter:

EXC 1975 Industar 50 F3 5 50mm M39 RF Fed Zenit ZORKI Leica KMZ USSR Vtg Lens | eBay

this is an Industar 50 Red P (non collapsible, with extension tube) for rangefinder cameras - uses M39 adapter

Industar 50 Hrome 1 35 F 50mm Red P 5821225 ZORKI Leica Fed EX | eBay

Personally, I would get the Pentax K adapter for the Q (with its integrated shutter), a Pentax M42 to K adapter, and the Industar 50-2. then you have an electronic shutter on a vintage lens giving you the most control.

sorry this was so long!

Hi. Actually, I wound up getting an m39 Industar 61 f2.8 / 55mm. It works very well on the Q. Very sharp & no PF at all. I bought the m39 version for it's compact size with the adapter compared to an m42.

I'd love to have the Pentax K to Q adapter, but $250 is too much for me to spend on it.

Q with 110 50mm 2.8

Some floral pics if you can get it in focus this lens is quite good for certain subjects,PF occurs on distant shots, but it so small & cheap $30 for a as new copy and $15 for an adapter..not much to have some fun..
the last 2 shots are 100% crop all OOC Jpegs ,only some contrast adjustment applied,no sharpening..

Here are some (cross-posted) with the 110 24mm f/2.8. It is a little soft and glowy, but I like it, and I think it will be great for people pictures. So tiny, perfect for the Q!

Bought the Auto-110 50mm lens, and I'm not particularly impressed. Images are a little soft, but the killer is the purple fringing. It's also difficult to manual focus, which is odd because the 50mm f1.7 K-mount lens is very easy to focus, even when stopped down to f2.8. It's just hard to see the peaking using the auto-110 lens for some reason.

I agree but I take a few shots at different parts of the peaking outline,and then I will get one in focus for distant shots its not so good, but its cheap to play with....the 50 1.7 is a killer lens on whatever camera I think and macro with rings works really well ..

The 110 lenses don't do bad if stopped down. My Q-110 adapter accepts the Lensbaby aperture discs. They just pressure fit in the adapter. The f11 LB disc gives approx f4 on the Q. The LB discs run $10-15 for a whole set. In the early days of photography waterhouse stops were the way photographers worked. Recommended.
thanks

I've been impressed with how sharp the 70mm lens is .. I can read magazine print from across the room (17 feet) ! Scary sharp at least in the center, while extreme edges show softness (so good thing using it on the Q!).
I have a custom small aperture disk in my adapter, PF is very minor.

Even better, adding the Soligor 1.7x tele-converter behind it pretty much eliminates PF and the need for any reduction disk (but also loose several stops of light seemingly) ..

it's an impressively sharp 650mm super-telephoto combo that fits in the palm of the hand!

Have to order them from a dealer that sells Lensbaby. Or maybe from Lensbaby's website. You want the replacement aperture discs ( f2.8-22) that fit the Muse and Composer double glass optic. Do not order the custom shape aperture discs, nor the fisheye or portrait lens discs.
thanks

The problem with the Pentax Q and any of these lenses without a shutter is the scan time of the Q. It takes 1/13th of a second for the Q to scan the sensor, during this time the sensor is active and camera shake and/or subject movement blurs the image, when you set a faster shutter speed your just altering the sensitivity of the sensor it will always take 1/13th of a second for a Q to capture the shot.

That aside the 110 lenses are quite good and contrasty, colour balance is good, the 18mm and the 24mm need stopping down, but the 50mm and the 70mm are OK even wide open. Though I still get the impression that the Q's sensor is out-resolving the lenses.

So with these 110 lenses is the focal length still multiplied by the 5.5 for the Q's sensor or what is the equivalent focal length of these lenses.

Yes to get the equivalent to 35mm you still multiply by 5.5x.
thanks

Thanks, that is surprising given their size. This may not be the right thread but what kind of manual lenses give you a normal - wide perspective on the Q?
