SMC Pentax 135-600mm F6.7

More than half a year after I acquired this imposing beastie, I finally get around to starting the lens sample thread for it

I barely had a chance to test the lens when I impulsively decided to lug it to one of my favorite hangouts - a local pond. I had the lens + K-3 II mounted on a monopod, which felt not entirely sufficient to wield the lens optimally. Couple my tenuous setup with a blustery afternoon and, well, it was a bit of a struggle. I had hoped to photograph a great blue heron who was a frequent visitor to the pond, but to my surprise I was treated to the arrival of a family of green herons.



cropped away about 2/3 of the frame


cropped about 1/2 of the frame






All of these shots were taken at 600mm, f/8 - f/11.

You needed that time going to the gym so you can carry that monster.

Very impressive results, Most impressive is getting that heron to stand still long enough to frame him using a tripod. Well done!

Very nice. That lens certainly deserves its reputation.

I would be really curious to compare this lens against the tampon SP 200-500/5.6 that I have.

It suffers all the same issues, specifically the tripod mount is way too far back to balance. Did you experience any purple fringing? How much did you have to do in post processing?

I like your shots. I have read that this lens has a fairly long minimum focusing distance, was that giving you trouble? It is one reason I got the Tammy, it focuses to about 10 feet (at 500mm) it is really goofed for the little birds

Nice find! I have been spending some time hand holding a Pentax 560mm f/5.6 this week...my shoulders are killing me.

You really should check what auto-correct is doing...

I haven't yet run into the long MFD issue, nor have I tried the included close-up adapter lens for it. I did have to correct for a fair amount of CA and PF in PP. Of the photos I've posted so far, the only one I feel I really "nailed" was the close-up of the green heron. Many of my shots had slight focusing errors, or shake, or subject movement. Not really a good job by me in charging into the fray with a lens I barely knew - in my experience it can take months to really learn a new long tele lens.

I do have the Tamron SP 200-500/5.6, and at some point I'll make a quick and boring comparison. My current impression is the Tamron is a bit sharper, and like you I enjoy the fact that it has a short MFD. I've recently acquired a better tripod and a long lens plate, so am now better equipped to compare the two lenses.

Using the K 135-600 for a couple of hours left me pretty sore, too, and I didn't even hand-hold the lens. It's pretty unwieldy on a monopod, plus having to fight the gusty wind and squat down at odd angles to photograph through/around the brush was uncomfortable.

The MFD is 6 meters, but that is reduced to 3.3m with the close-up lens screwed onto the front.

For a new (to you) lens and mounted on a monopod, I'd say you did exceptionally well on your first outing. I can't wait to see what you do with some practice and a solid tripod. Please keep the pics coming.

Superb shots for the first time out and all the monopod limitations!
