Kipon sells a Hasselblad V to K mount tilt shift adapter, and a Pentax 645 to K mount shift adapter. Not that I would suggest paying what they are asking to find out if it's worth it.

Godox TT350P vs Nikon SB800

The Metz I mentioned is a very compact package. The Godox TT350P is 140x62x38mm and 200g (w/o batteries), the Metz 26 AF2 is 110x63x26mm and 115g (w/o batteries). They're going for $63 on Amazon right now, although its from Amazon UK so have to wait for shipping to US, and I don't know anything about returns. I didn't want to return mine...
Kind of sounds like you're happy with what you've got, tho. But if you're ever looking for PTTL, don't overlook this one.

Welcome to the forums!

------
Here's the review of your camera, which may have some useful info for you.

The good news is most any K mount lens should mount. However, you will want to avoid lenses that don't have an aperture ring: DA, DA-L, FA-J, and most D FA lenses don't.
This website is a nice handy resource with info on the Pentax lens series, and Pentax Forums has an article covering the same info.

Even shorter, I would say you should stick to the K series, M series, and A series lenses, since they will be designed for manual focus.
If you find good deals on the F or FA series (or any DFA that has an aperture ring, I think there's two), there's no problem with that either but you won't be able to use the autofocus features built into it, and the focus ring may not be as optimal (usually shorter turn from infinity to closest focus) for manual focusing.

Also note that I linked to the reviews of the prime (fixed focal length) lenses, but zooms (variable focal length) would be perfectly fine, too. Here are all of the film era K mount Pentax lens reviews.

You can also use third party K mount lenses, as long as they have an aperture ring. The same preference for manual focus film era lenses probably applies. Definitely avoid anything newer that is designed for APSC (crop) sensor, labeled DC for Sigma and Di for Tamron, two of the biggest third party brands.

Finally, you can use M42 screwmount lenses, such as the old Takumars, but you will need an adapter. (Late Edit: after reflection about it I'm not %100 positive this would work so well given the camera's metering method... further investigation would be required if you want to try it out with m42 lenses)

There's a little more to it than all that (such as the Ricoh pin on Ricoh lenses, which otherwise should work), but that's the main gist of it.

------


Again, K (which have no letter in the name), M, and A series are probably your go-to choices.

I'm fairly sure all of the Pentax bodies perform as intended in regards to the weather sealing. Perhaps some of them perform more 'above and beyond' the intended ratings than others. What's weird to me is that you would keep killing them one after another doing things above and beyond the intended design. Seems like you might have learned your lesson at some point! Good luck selling your abused gear.

Two more very compact P-TTL flashes are the Pentax AF201FG and the Metz 26 AF-2. Each of them use 2 AAA batteries (which does limit recharge speed), offers bounce (but no swivel), and has a guide number of 20 (the Metz claims 26 but I believe that is (interestingly) only with the included wide angle diffuser lens attached). Neither can do HSS.


The Metz is from a company that has gotten out of the flash business and is no longer supporting their products, but it has simple enough features that it will probably function with the camera %100 as intended (it does with my K1, I haven't tried on GR3 or any other camera). PTTL, slave mode (with certain other Metz flashes only), and continuous video light with two power levels (I sometimes use it as a flashlight) are the only options. No manual mode. It does use 2 AAAs despite sometimes being mislabeled online as AA. It was manufactured in Germany and seems nice and robust.

The Pentax also has somewhat limited functionality, although it does have 1/1 and 1/4 manual modes, as well as a choice of leading or trailing sync PTTL. It will work as slave with other Pentax flashes or built in flashes on Pentax DSLRs. It is weather sealed, which is nice. I have no experience with that one, but it is reviewed fairly well here.

This is, I believe, the Kenko to get, and is also available in other brands (there may or may not be slight differences). "PZAF" is a good search term to help find one.
The Pentax offers AW, and also will report the corrected focal length to the camera for SR and EXIF data.

I know that stuff, and hope it helps, but I've not used the Pentax so can't comment how they compare.

I'm more convinced now, but still not %100 sure. Have you tried yet using magnified live view? And if not is there a reason for that? The other question is whether it's on a tripod with self timer or remote? Shake really does matter a lot, especially at these focal lengths.

BTW I'm not implying you're doing something wrong, I just know that with long lenses, there is a whole ton to be gained by improving and then refining technique. The people who post amazing shots with the same lens as others who are frustrated with results from their first supertelephoto; I tend to have a hard time thinking it's variance between the lens copies, rather than variance between the photographers' skills.


One place where these shots clearly show the advantage going to the mirror, though, is the purple fringing. Check out those branches in the foreground with snow behind them!

I hope you're having fun doing these tests. Keep at it (plus real world shooting of course), and I bet your shots from both lenses will continually improve :)

From the shots you're showing I don't think there's any question the Pentax zoom is providing more detail and more contrast. I do still sort of wonder whether imperfect focus issues are coming in to play. I would say manual focus, zoomed in live view, for both lenses, would be a better test.
I'd also be interested to see the two compared shooting the moon.
Good job doing comparative testing, though. I always think I'm going to get around to it, and then I never really do. Or when I do I don't keep good enough notes about what I shot to be able to interpret the info.

Compact/Travel Tripod capable of handling 150-450 lens
Posted By wadge22

Really glad I could help. Yes, I think the shorty tripod is a great buy.


I might still weigh your options considering heads.

Gimbals are great, but I sort of see their best use case as being tracking moving objects, such as in sports, airplane, or bird in flight photography. They also are more of a pain for any lens that doesn't have it's own tripod foot. Is the 150-450 the main lens you will be using for all of your shooting with the head?

They also just aren't super rigid when tightened (at least mine isn't, altho maybe it's better with a brand new mid to high end gimbal; mine was well used, and a store-brand/knockoff one) the way that a large diameter ballhead or a geared head is. I see gimbals as somewhat specialized for long lenses and high shutter speeds, where they excel, and merely adequate for long exposure rock solid type of shooting like astro or landscape. Is the eclipse and similar use cases your primary need for this purchase, or just the minority use that happens to be prompting you to buy right now?

Not trying to talk you out of it. I think you will be happy either way. Just like to see folks fully consider the options to get the best thing for them.

Focus issues: solutions?
Posted By wadge22

-The new camera you're talking about is K70, not K700. It's a very capable camera for the money, and I've never heard of anyone having consistent autofocus issues that couldn't be resolved. It is possible you'll have aperture block issues with that camera (others might have more info on the likelihood of that happening).
None of the rest of the cameras I'll mention commonly suffer from that problem.

-K1 is significantly more expensive (if you get one for under US$1000 used right now, you've done very well, and you would pay US$1800 for a new K1ii, which replaced K1 but is largely the same camera), but it's very nice (it's full frame as you noted, as well as various other advanced features). You may well not need that much camera at this stage, although I can't say that for sure.
It too will autofocus capably, although still not as fast as more modern cameras from some competitors or the (US$2000) K3iii, Pentax's newest camera and it's best autofocus performer ever (a significant upgrade for the brand, which has long lagged somewhat behind the competition if AF speed)

-Another possibility would be to get a used high end crop camera from several years back, like maybe the K3ii (probably comprable price to a new K70). It will absolutely be more capable at AF than your K100D Super, and probably be more durable than a new K70 (definitely the aperture block) since it was top of the line when released. Remember, your K100D Super is 15 years old at this point, any newer Pentax will have improved autofocus over that model.

-Here's a comparison of some of these models. There are links there to the staff and user reviews for each camera as well, which should have plenty of info.

-All that said, it's possible that your current camera can focus okay with different techniques or settings, or possibly if there is an issue with the camera or lens that we can help diagnose and maybe correct. As pepperberry farm mentioned, posting some shots with exif data would be the next step to getting to the bottom of that.

A few more notes:

-Newer cameras will allow zooming in for manual focusing with the back screen in live view (your K50 might, I'm not sure), and have focus peaking which is very nice in most situations. They also can use the AF system to give focus confirmation (a little square lights up where the picture is in focus) through the viewfinder. So a split prism isn't necessary to use MF lenses, although you still may end up wanting to go that way (I have) if you continue using MF lenses.
Live view (not using the viewfinder) is always the most accurate way to manual focus, even with a split prism installed.

-Some modern lenses do have electronic aperture, but not all. There are still lenses from Pentax with the aperture ring.

I hope any of that might be helpful to you, there was a lot to respond to in your post and I didn't get to all of it.

Compact/Travel Tripod capable of handling 150-450 lens
Posted By wadge22

Alright, @PentaxScott, I pulled out the mini tripod. I take back my reservations. I believe a tabletop tripod could work just fine for your situation.

The ball head seemed to allow pointing straight up, and the gimbal allowed about what you would need with the gimbal load still balanced. Could have gone further with adjusting the tripod legs or changing the balance on the gimbal.

I don't have the same lens as you, but im fairly confident you would be alright. I was checking with a Tamron 60b, 200f, and K1.

Both rigs felt pretty rigid, the ballhead probably much moreso (maybe not what I would have guessed). I will say that the leveling base (my non built in to the tripod version) introduced the most loss of rigidity to the setup, and for astro type shooting I would have removed that and just mounted the ball or gimbal directly to the tripod. I still would have preferred the tripod with the leveler built in.

Hope this may help, and please choose whats best for you based on all info and not just my (or any other single) recommendation. Good luck with your decisions.

I still think you would be okay, but I'd hate to be wrong and influence you to buy the wrong thing. It's mostly gonna be dependent on the head you use, whether there's any physical interference with the camera body when pointed that high upwards. A lot of the gimbal heads can have the 'floor' adjusted upwards which would help with that (sorry, can't think of a better way to describe it right now), but that makes them less well balanced (which balance is the whole point of the gimbal).
And I would say that, even with the legs splayed out at their widest, the shorty tripods will have a harder time dealing with wildly unbalanced loads than full sized tripods. When I say they're extremely stable, I am sort of assuming that the mass is well centered over the middle of the legs. Things get 'tippy' (even if still not 'shaky') faster the less wide out the legs are spread, and shorter legs inherently mean less wide spread.

I've mostly used mine for wildlife/birds when paired with my long lenses, therefore aiming pretty low to the horizon (at least compared to 70deg). Maybe someone who shoots astro can comment on what challenges aiming high up with long lenses presents, and how to deal with them.

Adding: I can play around tomorrow with my stuff and report back. Probably won't be able to provide pictures (I haven't established a very good workflow for posting pictures up here yet), but I can describe what I've found out. Most everything is in the bedroom where the lady is sleeping right now, so I don't want to rummage around in there to get it out tonight.

Best zoom macro lens for Pentax?
Posted By wadge22
Replies: 29

I think this Vivitar Series 1 90-180 lens might be the only one I know of you maybe could say is a macro zoom. It's only 1:2, and even that is only at the long end (180mm). Some people won't acknowledge 1:2 as a macro, anyhow. Also, that lens is pretty old and very rare in K mount.
There is also the Tamron Adaptall2 35-80mm 01A, which definitely isn't a macro, but does do close focus (macro mode, and a pretty convenient implementation too). With an 01F 2X TC, it achieves 1:1.25 at 180mm (IIRC). A lot of people like that lens for it's macro-like capabilities; it's mentioned in just about every review. I remember seeing one forum member post absolutely amazing macro results with that lens and a Raynox or similar filter, but I couldn't find that thread. It's also just a really nice lens all around, and not terribly expensive. Adaptall2 does have it's drawbacks, and isn't for everyone.

If, as others have guessed, you're really just after a long telephoto macro, there's the Irix, the rare Sigmas, and the rare and expensive Pentax 200s.

I do think so, although it will necessitate stooping down to see the screen (absent wifi tethering, or if it's set up on top of a table or rock or the like). They are extremely stable with the legs splayed out wide. You will still want a good full fledged head on it, and for long lenses a gimbal type has definite advantages IMO.

I'm not sure what declination the eclipse will be at; this option may start to be impractical if it's close to straight upwards. In that case even a flippy/articulating screen could be hard to access, and you could run into physical interference of the camera body with the ground, tripod, or head.

Nevertheless, I really like mine. If you can get one with a leveling base, which is under the head and allows for some leveling adjustment without using the legs or head, that is ideal. Those are very useful for gimbal heads, and also for ballheads that have a pan feature. The Berlebach one I linked has it, and the Leofoto one I linked has a counterpart with the leveler, although it's only rated for 11lbs (not sure why, probably just the extra projection upwards of the COG). They can also be bought separately and put on top of any tripod (I've got this one, which I put on top of my Berlebach because I didn't know I wanted it when I bought the tripod), but that will add to the cost compared with getting it built in. It would then be usable on a full size tripod later, though.

If buying one of these, and planning to use it as the base of your monopod setup for your Theta, I would make sure in advance that there's a monopod/extension available that connects to the standard tripod plate. I would guess so, since it's about the most standard attachment there is: a 3/8 thread with a wide flat base. I don't know anything about those, though. I've seen the video monopods with the 3 tiny foldout feet, and those might work for the Theta, but won't do a thing for your 150-450 + DSLR shooting at the sky.


All in all, since you say you want a tabletop tripod anyways, this might be a good way to go. It will let you put more of your budget into getting a top notch head, which should always be something like half of the package (some people overlook that even if they get a nice sturdy tripod).
Just double check that everything is going to be compatible for all the uses you have planned for it. And be ready to be the guy squatting down while you're trying to get your eclipse shots :)
