Which tele zoom as an adapted q lens?

Hi,

I managed to buy an used Pentax Q a few days ago, I also ordered the Fotodiox adapter with aperture control. As primes I have 100mm 2.8 Macro WR and M 135mm 3.5. I think for my purposes it will come in handy to add a zoom in the adapted lens department. I thought of some convenient, cheap lens in the range 35-300mm. For the start, maybe a 35-80mm will do it as well. What about 55-300mm hit lens or 50-200mm?

I already went through some of the other threads but could not come up with a decision of what to get next...

Any recommendations which inexpensive zoom lens will yield somewhat good results (maybe as good as the 135mm, which sample images i like a lot)?

I went through the exact same conflict a few days ago. For me the solution was to get a M42 to Q adapter and grab a very sharp SMC Super-Takumar 200mm f/4 M42. Or you could also grab an M42 to K adapter and use it with your photodiox.

Apparently the Q when used as a super-duper-ultra-mega-telephoto camera, it begs for sharp glass.

For me, this was the cheapest way of getting a half decent tele on the Q.

The M 135/3.5 works very well for me, plus it's nice and small.

As far as zooms, the Promaster (Tamron) 28-105mm f/4-5.6 also works well.
Link to my tests here.

yep...already done that but still undecided. I am interested in how well pentax A, F, or FA zoom lenses work and cant find a resource. Or some of the Vivitar zooms / Sigma zooms (Sigma 35-80 macro?)


Thanks for your quick answers! :-)

Best advice I can give is the sharpest zoom will be the sharpest adapted zoom. In the affordable class the ones I have owned are
  • Vivitar Series 1 PK/A 70~210/2.8~4 ver. 3 (be careful of the Ricoh Pin)
  • Tamron Adaptall-2 SP 70~210/3.5 19AH (cooler and maybe a bit sharper). Not necessary to get a PK/A adapter
  • F70~210/4~5.6 (under appreciated lens overall)
  • A35~105/3.5 (the classic 'stack of primes')
  • M75~150/4 (another under-appreciated lens - can be had for under $50)
Any of these will do nicely.

Look at the thread for lenses adapted to the Q

I have had good success with the vivitar Series 1 70-210/3.5 (version 1)

I intend to soon try it with my Adaptapp II 200-500/5.6, but that is a rare beast and not cheap

I have the SMC F 80-200 and the SMC M 135 f3.5, both are sharp on the Q and Q7 and great to use, check them out on the adapted lens thread. The first post has a chart of all the lenses tested.

Thank you all for your replies. I think I will look out for the Pentax A 35-105 f3.5. This will also fill a gap for my K-5 between DA 40XS and 100mm Macro. :-)
In my imagination it will be quite fun to play around with a super duper zoom telephoto on the Q. Hopefully I find me a nice 35-105mm...

Note the 35-105 is roughly equal to a 150-500mm on full frame. Might I suggest you go a little longer

Actually, I think what is important is to look at the focus throw. A lens with a short focus throw might become problematic in terms of focus accuracy as the crop factor makes this much more apparent than on either FF or APS-C

It is tempting to go longer, but I will shoot handheld exclusively and dont think that this is still possible at some point. Or am I wrong?

I use a third party loupe from a Nikon on the LCD to make it an eye level viewfinder

Similar to this one

http://www.amazon.com/2-8x-viewfinder-loupes-Nikon-Camera/dp/B0030DKH84

I have had good results using both my K135/2.5 and my series 1 70-210/3.5 hand held, but used like an SLR. You can also put a monopod under the mount on the adaptor and still have a light weight kit. Given the crop factor of 5.5 at 210mm you are at 1150mm equivalent focal length ( compared to 35mm). I am looking to go longer, with my 200-500/5.6 but that lens is already tripod bound. I have only once hand held it and that was in the store to just evaluate whether it would be useable and sharp enough

Yeah, I saw something similar already in another Q thread. I would definitely enjoy shooting with such a loupe. My questions are: Are controls on the Qs back still accessible? Is the nikon loupe for the N1, which link you attached, usable with the Q? I saw a seagull branded loupe somewhere which seemed quite cool, too.

Do you think this will this work?

I've tried a few on my Q...

1) Pentax A 35-105: Excellent lens all-round, but it's kinda heavy & bulky on the Q. Still, it works well, and it's a killer DSLR zoom. 200-600mm equivalent on the Q.

2) Promaster 3.5/100mm macro: Lightweight and excellent for long tele handheld shooting, as long as you have a steady hand. 560mm equivalent on the Q.

3) Pentax M 3.5/135mm: My go-to super tele for the Q. It's compact, and the built-in hood is very cool. Performs well if you stop it down a bit. It's a whole lotta focal length in a tiny package. Gotta have a very steady hand, though. A whopping 756mm equivalent on the Q.

4) Here's one no one's mentioned so far: Pentax A f:4/35-70mm: This is one I nabbed in a thrift shop for 50 cents. I thought it might be kind of a dog, but to my surprise, it's quite an excellent performer on both the DSLR and the Q. It's a very easy to shoot with and compact 200-400mm equivalent tele zoom in the Q.

Of those 4, I usually use either the Pentax 35-70 or when I want more reach, the Pentax 135. Another good thing about these two lenses is that they're cheap & easy to find.

Regarding the loupe,

I have the same loupe & it works great. After using a Dremel tool (you can also use a small grinder drill bit) to lengthen the tripod screw hole in the metal bracket, it's a perfect fit for the Q, and all the controls are easily accessible. Only downside is that once you enlarge the hole, the tripod screw won't stay on the bracket. Not a big deal, cause I keep mine on the Q at all times anyway. Also, you'll want to use an upward motion when detaching the loupe from the bracket, because it's flimsy metal and will bend away from the camera if you pull the loupe off in a downward motion rather than up. Also not a biggie, cause you can easily bend it back.

A loupe is an absolute must when shooting with a long tele on the Q, in my opinion.

Cheers,
Bob
