The Q reference thread: Adapted Lenses

This is a centralized reference thread housing a database of experience and results of different adapted lenses that users have tested on their Q series cameras.

Information that each Lens Review should have: description of your results, the camera used (Q, Q10, Q7 or Q-S1), recommendations for best use, specific adapter brand or source that was used, and a sample image so a user might see what to expect.

To make this thread easy to search it will be important to put the lens name in the reply title (use the advanced reply,) that way a user wondering how their lens might work on the Q can do a search on title only and quickly get to the lens they are interested in. I think it is OK to have a lens reviewed more than once as different users may have different experiences and use cases.

Please try to minimize discussions here to keep this thread easier to navigate

Here is an index of the lenses submitted to date: (Will try to update this index regularly, but make sure to identify lens in the title)

Outstanding idea. I'll try to get my 85/1.4 shots sorted and post one soon. +1 for starting this.

Pentax DA*300

Of the tele lenses I have tried so far on the Q this is clearly the one that gives the sharpest results with highest resolution and no hint of CA.

I have used the DA*300 extensively with the Q, initally with the Fotodiox with aperture adapter from Amazon and most recently with the Pentax OEM adapter.

My testing with this lens has been strictly on a tripod, as I am not steady enough to try it hand held at the resulting 1650mm equivalent view.

Best results with my copy are achieved at f5.6, or '1' setting on the Pentax adapter.

A scope or finder of some sort is recommended if you need to be able to acquire the subject quickly, as the field of view will be tight.

Pentax DFA 100 WR Macro

The DFA 100 WR is a good choice to use with the Q. It will give a usable tele view equivalent of 560mm and due to it's 2.8 max aperture it can be stopped down a bit before getting into the Q's diffraction territory. I have used it with the Fotodiox w Aperture adapter as well as the Pentax official adapter.

This lens yields good results at f5.6 ('2' on the Pentax adapter) for telephoto use, and can handle smaller apertures for macro where depth of field trumps diffraction effects. Wide open the lens will tend to show some purple fringing on the Q and loses a bit of sharpness.

As a macro lens the Q lets you take this lens much further than 1:1 as you can get just as close but are essentially cropping the shot with the sensor.

Using the Pentax adapter allows external flash to be used up to 1/250 second if you are accustomed to lighting your macro shots with flash. Other adapters limit you to 1/13 second on the Q and 1/30 second on the Q10.

This lens can be used effectively hand held due to it's small size for both telephoto and macro applications. The sample below was handheld using the Fotodiox adapter.

Sigma 70-200 2.8 HSM II

I own the HSM II version of this lens, which natively is a little soft wide open but sharpens up once you stop it down a bit.

When I initially tested it on the Q I was disappointed with the results.
The images were hazy and lacked contrast, almost like they were shot through smoke.

User Barondla suggested internal reflections might be causing the issues and I noticed that the HSM II has a lens element at the rearmost section near the mount.
The Fotodiox adapter also had a semi gloss finish internally so I decided to take a chance and coat the inside of the adapter with flat black paint to absorb any reflections.

The results after painting the adapter were drastically improved, the images no longer exhibited the smoky appearance, and I found that dialing the lens to 5.6 yielded very good results on the Q.

Once I acquired the Pentax adapter I was pleased to find that the design and finish of the adapter did not cause any reflections with this lens and it continues to be a usable choice with the Q.

The Sigma 70-200 is an excellent choice for the Q as long as you take the precautions mentioned regarding internal reflections on the third party adapters.

The lens exhibits no tendencies for CA, and gives sharp results at f5.6.

SInce I had previously only tested tele primes, it was nice to be able to have a good quality tele zoom that could allow me to widen the shot if needed, going from approx 350mm equivalent to 1100mm equivalent on the Q.

Great idea crewl1! The number of Q users is expanding daily. This will consolidate adapted lens info into one easy to find thread. Will see if I can add some lenses later on.
thanks

Pentax FA* 300 f4.5

The main reason for purchasing a Q was to use it adapted to my FA* 300 4.5 lens after seeing such great results from others here with their long lenses. I just had to try this out for the great magnification factor. Of course, I really fell for the Q since I've had it and use it with native lenses also.

It is late fall/early winter now, so I won't have a lot of good wildlife images until the coming spring and beyond. This represents my first day of initial testing of shooting through double pane glass at one of our bird feeders. I will update this post later in 2013 when I have the opportunity to get outside and do some serious shooting.

I am very pleased with the results. I was using the Fotodiox adapter that is unmodified (unpainted interior). I set the ISO at a static 125 with the lens set at f5.6 for this shot. I let the shutter speed float since I was on a sturdy tripod. I tested the lens wide open also (f4.5), and the only real difference I saw was a little less contrast. Those are the only two aperture settings I tried in this session - I will try other combinations when I get to work outside.

Not the best photo as far as composition, background, etc. - this was a testing session only to see how the fine feathers of the bird looked.

Q - ISO 125 - f5.6 on adapted FA* 300 4.5 lens - 1/50 sec

Awesome idea! After I get my Q & put it through it's paces with different lenses, I'll post my findings. I'll be putting this thread in my favorites. :-)

FA 50 f1.4

I'll start with the FA 50 f1.4. With the Q's 5.58x crop factor, this is the equivalent FOV of a 279mm on a 35mm, but I think of it more as a 180mm EQ on my K-5. It focuses closer than my A* 200 f2.8 (1.5 ft vs 5.9 ft) and is a full 2 stops faster, so I can use this lens on the Q when I need the speed or close focusing and the tight FOV. The lens that's closest for me on my K-5 would be the Sigma EX 180 f3.5 Macro, and it's pretty much a beast -- about as big as an average 300 f4.

Here's an example -- This little Screech Owl is a rescue at my local Nature Center. She has a bad eye which would hamper her while hunting. She lives in a 4'x5'x5' enclosure surrounded by about 1" mesh. Here, she's 3 feet away and I rested the end of the lens for stability, and this made the mesh disappear. I used f4 to get good DOF and still had 1/100 sec at ISO 200 to keep the effects of camera shake minimal even without SR at this time.



I plan to use this lens for people candids at parties with available light. I'll probably use a 3rd party adapter to make the camera totally silent. It will also get used for indoor zoo exhibits where the short focusing distances and FOV will work to get tight shots with the lens close to glass to cut reflections, and the f1.4 max aperture can give me much faster shutter speeds in the dimmer light.

Pentax Auto 110 70mm f2.8 + Nikon 4T (+3) closeup

I was a bit disappointed with the Auto 110 lenses as very compact telephotos on the Q, but I'll have to give them another try with Focus Peaking and SR -- and maybe try making some aperture discs to stop them down to @ f4 or f5.6.

However, this shot convinced me that with a good achromatic diopter, the 70mm has some promise as a close up lens -- not high magnification macro, but maybe for small object product shots and close ups of small animals. DOF with the Nikon 4T (+3 diopter) is thin, as can be expected, but not razor thin, and at f2.8, it's pretty fast.

This is at ISO 200, 1/100 and, of course f2.8

DA 18-250 f4.5-6.3 at 250mm

Here's an early shot handheld with the DA 18-250 at 250mm f6.3. This was before FW 1.1, so no SR. It was shot at ISO 125 at 1/350, so at about 2 stops slower shutter speed than the "rule of thumb" 1/FL EQ (in this case 1/1395). I was leaning against a post, so got some help.

First is the shot just resized in steps, no PP. you can see it's soft -- the DA 18-250 is a good lens, but as a super zoom, it can really only be so good -- the Q is fussy about glass -- and at f6.3, there is some diffraction goin' on here. ..



Close inspection showed that there is very little camera shake effecting the shot, so I did my normal sharpening in PP and here's the result ;



Not eye popping, but not too shabby, IMO -- and where can I get a 28-900 EQ zomm for my K-5 for the $300 I paid for my DA 18-250?

Not my first choice in lens for the Q, but I'd use it.

Scott

I would like to contribute but I know next to nothing about photography. I could literally only post the lens info and some basic shooting information. I wouldn't know where to start when it comes to reviewing the lens. If that is okay then I will take all my lens tomorrow to the park and get samples with all of them. Hopefully we have a sunny day tomorrow (I doubt it)
