I think Pentax 110 lenses are quite good companions for the Q. They offer good image quality, have quite good coatings (maybe not SMC, but they work good), are small (this is also the case for the adapter) and are usually cheap. Pentax also made dedicated close - up filters for them which is also nice. I will post some photos and share my experience with my 110 lenses in this thread, but maybe also other Users could share their experience and discuss here?

Below I attached some photos from my 18 mm lens stopped down to about 5.6. This is a joy to focus this one manually. MFD is 25 cm and the quality in close-up range is really good. This one weights about 30 grams. I have it not for a long time but I really enjoy it!

The images look good. I thought those lenses were all f2.8 and the aperture was at the 110 body?

Yes, you have to use a disc with a hole in it placed in the adapter to "stop down"...

I just got the genuine Pentax close up lens for my 110 - 18 mm lens. It is simple, small (30,5 mm thread) and definitely easy to carry with. It is one element diopter but was dedicated to this particular lens and I like the results. The Pentax 110 close up lenses are quite easy to find on auctions and relatively cheap.

Below I post some images showing briefly the magnification and quality.

First the lens without diopter at its MFD - 25 cm - image not cropped.



Then with the W21 diopter added, also not cropped.



Then one more time another test with the diopter and lens focused at 25 cm.



...and the 100% crop from the above



Maybe the test subject was not the best one (part form cheap plasticky lens so not so spectacular when looking really close). All my images are made with the original Q camera.

I procured a set of the 110 lenses and the disks to change aperture and while your images look quite good, in my personal experience I found the image quality not to be anywhere near what I get out of the regular Pentax lenses.This combination would be similar to the 06 lens which is one of my favorite lenses for the Q series.Unless you are shooting with the 50mm or 70mm 110 lenses, which produce focal lengths not yet available with a Q series lens, is there some advantage besides costs to using these lenses.

I love the lenses. If you want manual focus lenses on the Q they are perfect - they are tiny and they are smooth to focus with a decent throw (unlike some fo the AF K mount lenses). Full size Pentax K mount lenses may ultimately get better results, but to mind the tiny Q is no longer tiny and balanced with them in place. Better still, if you look out for a full Pentax 110 kit you can pick up the lenses for buttons as for some reason the lenses seem to make more on eBay sold individually than as a full kit with the camera.

I have to say that I have no genuine Q-series lenses (I bought Q body as a "teleconverter" camera). For me the main advantage of these lenses is fun. Regarding buying - I agree with the post above. Sometimes the best deals are also auctions for camera with lens/lenses. Another thing to mention is that it is good to buy them with filters. They mainly have not standard threads (25.5, 30.5, 37.5), so the deglassed filter may be needed to "construct" DIY hood etc.

Below one photo from the smallest P-110 lens - 24 mm. This one has only about 13 mm and takes 25.5 mm filters.

Piotrek K, nice images using the Pentax 110 lenses. Your shots look really good. Love the B&W. The 110 lenses are so small they make even the #01 lens look huge.
thanks for sharing

I saw some great images with 50 mm 110 lens stopped down with DIY apertures, but some people also state that it is sharp or not bad wide open. Could someone share the experience with or show some images and crops showing how good/bad it is?

Looks great.

Transit - looks great! Hopefully also other P-110 lenses users will share their photos/experience/tips here.

Image below taken with 18 mm plus dedicated W21 clos-up diopter on the (first) Q.

Pentax 110 70mm on the original Q stopped down to about f4.5 with a blackened ringbinder reinforcing ring stuck to the rear element mount.
Although not blazingly sharp I think the 70mm on the Q has the makings of a great surreptitious portrait setup.

Is there any dedicated adapter for using auto 110 on q? given the Flange Focal distance of 27mm for auto 110, it should be possible to have an aperture iris built into such an adapter...? Does anybody in here know about such an adapter on the market ?

[GUB]

This is what a lot are using.

I personally just felttip a ringbinder reinforcing ring black and stick it to the back of the lens. that comes out about f4 to f4.5.
Of course it is important to have the iris as close as possible to the lens otherwise it will start vignetting the image.
Adapter easily available
