Sorry, I don't get your point? I never said anything against the 55-300, it's a great lens as well. If it suits your needs, all good, but if it doesn't suits the needs of others, they have the right. Just like they have the right to wish for lens X or Y having no alternative, to avoid having to switch to another system.

That's an APS-C only, f/8, poor IQ, high vignetting and slow focusing lens. Pretty far from even the worst/cheapest 150-600 available, while both much heavier and much more expensive...



Likely because "way too many" people would buy one, just look how Tamron & Sigma's 150-600 sell like hotcakes. But while I indeed see a lot of people asking for telephotos lenses, not so many are asking for cheap ones, nor for zooms.



Why is it so hard for you to understand that people may want lenses that do not interest you, especially when the lens in question is a best seller of other brands, with no alternative in the current lineup? I don't want a cheap telephoto either, but I'd see it as a welcome addition. Many people do wildlife only occasionally, not having this option is a real shame. We should all hope for Pentax to make them rather than advising every people who'd like lens X or Y to switch brand... There are still a few gaps to fill in the lineup, the cheap telephoto is one of them, among an ultra-wide (ideally with good coma performance for astrophoto) and a fast telephoto. Mostly all the rest is covered, often with several choices.

As for the downsides:
- you're comparing apples to oranges, there's a world between the IQ of a $400 body + Tamron 150-600 and a K3-III + a 150-600 equivalent. If you want an equivalent IQ you'll need to buy something like a Nikon D500. Pretty far from half the K3-III's cost...
- you'll either need to cary an additional body, or switch system altogether. First option is not practical at all, second option is super expensive. Selling Pentax gear is close to impossible (at least here in France), so switching system means rebuying everything (in my case, that's at least 8k€). No longer that cheap, right?
- many of us do not want to go mirrorless. Buying a reflex body in another brand than Pentax isn't very wise, there will be no successor. Mirrorless options are not cheap, at least for now.

The IQ of the 150-450 is much, much better than DA* 300 + DA 1.4, and you get a bit more reach. On the downside it's heavier and a bit more expensive, but totally worth it ;)

Pentax Meeting on Nov 27: K-3 III evolution (firmware and model variants)

Thanks for the report, glad to see that they found a way to add astrotracer without the need of the GPS 👍 !!

For the 6 variants, the astro version is very interesting, looks like they pay attention to astro these days 🙂 . But if they want to be "the" astro brand there's a bit of work on the lenses as the Samyang 14 f/2.4 & 24 f/1.8 are not available in Pentax mount. I just bought the Laowa 12, coma looks ok at f/4 or more, it's not bad but not good either (and the flare resistance is awful...). The Samyang 14 f/2.8 is likely better for astro but its distortion made me choose the Laowa.

I have yet to see a report on the 21 ltd's coma performances, but I don't think it was design with this in mind.

Interesting!

1: I already have (and love) the DA* 300, so I'm not interested
2: too close to the 150-450, I hope they won't do this one instead of the others, I don't get the point 🤔 . A cheaper/lighter version I guess, but I think it's much more important to fill gaps rather than offering a bazillion options for the same focal length (as they did with the ~50mm 😤 )
3: It would likely sell like hot cakes looking at Sigma/Tamron versions. I may be tempted but f/6.3 is pretty slow 😕
4: Now we talk 😅 . Looking at the 250-600 size, starting at 125 might be ambitious though! That would likely be a ~10000 lens as well, if so it has to deliver 🙂

Glad to see some discussion about long lenses 🙂 . I'd love to see some options which have no alternatives (rather than another 100ish-400ish a bit different than the 150-450). I'd definitely purchase a 500 f/4 or 600 f/5.6 (after some savings time, of course... 😅)!

HD Pentax DA 560mm f/5.6 ED AW replacement : what are your thoughts ?
Posted By timautin

They released the K1, one of the best landscapes body available, with no modern landscape lens (and that's still true today as we're still waiting for the 21).
Now they release one of the best wildlife body, and they remove their longest lens...
Go figure 🤷 ...
Luckily the 150-450 is a gem, but it's sometimes a bit short, and I find the IQ loss when adding the TC way to high. I'd love a 500 f4 or 600 f5.6 prime, but I don't see it happening 😕

Not my experience either: mine is wide open comparable to the DA* 300 (a very little bit softer, but you can't notice that without zooming at 100%), and it is much better than DA* 300 + 1.4 converter (which I thus never use).

Like what others have said, your copy has likely a problem, and probably need at least AF adjustments (but that's hard on a zoom), or a repair.

Thanks! I don't have the 560 to compare, but vcollerp on Flickr has photo albums of both lenses (he also has the F* 600 f/4): vcollerp?s albums | Flickr .
Like for the DA* 300 vs D-FA 150-450, I don't think we can differentiate the IQ between these lenses without pixel peeping at 100%. The difference is more in the size, AF, zoom or not, reach, weight, max aperture and price.

That's a roe deer (Capreolus capreolus), common in France. The bee-eaters on the second shot are much less common, but they easily accept a hide. Then you "just" need to be in the hide before the males arrive to the colony (females sleep in the nests, the males a bit further), and leave after they left it. I shot the kingfisher of the 1st shot at the same spot.



I never used another system enough to make AF comparisons, but it certainly suits my needs. It's a bit better than the DA* 300, and light years ahead of the Sigma 70-300 APO I started with. Which was by far my worst lens by the way. This is not suitable for BIF... And the AF was so noisy that to get a chance to take a shot I needed to switch to MF, do a manual pre-focus, switch back to AF (no quick-shift...) and then focus. All that while by being my softest lens at the same time! After using that thing every AF system seems amazing :lol: .

If you're after BIF shots, I'd wait the first tests of the K3 III before purchasing a new body, as it has a completely new AF and brings birds tracking ;)

Here are a few others:

Glad to help :) ! For the body, I'd wait the K3 III release: compared to the K1 you'd get better AF, lower noise at high ISO settings, 3 times the burst, and 1.5 times the reach. The only downside is the lower resolution, and worse field of view.



I nearly never use manual focus, only to take identification shots of animals in the darkness at crazy ISO settings ^^



I have some with the K3, but not with the K5 (I bought the K3 before the 150-450, and stopped using the K5). I'm on my phone right now and for whatever reason the photos of my post are not loading, just the text. Aren't there some small birds portraits in the photos listed under the "K3 + 150-450" line?
Anyway, you didn't tell us what you intend to shoot with that lens? Close ups of what?
I also have the 1.4 converter, I prefer not to use it (I find that you loose too much sharpness, and prefer to do my best to get closer to the subject). IIRC using it with the 150-450 on the K1 is not a good idea (to much vignetting).

It's not clear if you're asking help to give some mercy to your wallet, or to convince yourself / your wife?

If the former, stop scrolling, close this window, and never come back. You've been warned :lol:

K1 + 150-450:

































Now, the lens isn't taking the pictures, we do. A K10D / K7 / K5 / K3 / KP + 55-300 or DA* 300 f/4 gives very similar results than K1 + 150-450 if you don't zoom into the picture.

K3 + 150-450:







Here are older pictures of only 800px (back then internet speeds were not wat they are today). I just give you the links as Pentax Forum would upscale them, making them pixelated. Opening them in a new window should show them at the right size.

K5 + DA* 300 f/4:

http://timphoto.free.fr/_ressources/_photos/_grandes/193_Renard_roux.jpg

K10D + DA* 300 f/4 (even on my 27" 4K monitor, this is plain sharp. You can't zoom into the picture a lot of course, as 4K is 3840*2160 = 8.3 mpx, which is nearly the 10 mpx of the K10D):

http://timphoto.free.fr/_ressources/_photos/_grandes/207_Gorgebleue_a_miroir.jpg
http://timphoto.free.fr/_ressources/_photos/_grandes/203_Cordulie_bronzee.jpg

To sum up, the 150-450 is an amazing lens. So amazing that I never used my DA* 300 since I bought it, and the DA* is absolutely fantastic as well. But if today you don't take pictures similar to the above with a K-whatever + 55-300 PLM or DA* 300, the 150-450 won't change anything, nor will a K1, or any lens / body. If you are beginning, I recommend you to start with a 55-300 instead (or the DA* 300 if you're not on a budget).

Finally, the monitor on which you process and select your photos does imho a huge part of the job. I currently use a Dell U2720Q (4K 27"), previously an iMac (QHD 27"), and previously a 13" MacBook (1280x800 IIRC). Going from the MacBook to the iMac was at least as much a leap forward than going from APS-C to full frame. It didn't make me take better pictures of course, but enabled me choosing the sharp ones. QHD -> 4K is another big step (but requires good / young eyes).

If you want some full res JPEGs or DNGs, I can send you some.

Hope this helped ;)

New K-3 III video from Ricoh: OVF face, eye and bird detection is coming.

We'll see, they may have a nice card to play here. ML has great advantages but big drawbacks as well. After using an Olympus ML a colleague wants to go back to an optical VF. Pentax now seems to be the go-to choice. He came at me asking about the KP. I lent him my K3 & K5 with some lenses, he's now on the watch for a KP. Despite my warnings about the fact that (while making money) Pentax is now a very small company, in a very small market.

Pentax has now addressed 2 major complains one could make: lack of a modern wide angle lens and lack of human/bird/eye tracking AF-C. That leaves a rectilinear FF UWA (~11-12 mm) and long lenses to cover nearly everyone needs :) . Pretty impressive for such a small team. If I was a troll I'd say that it's nearly embarrassing for the big guys. But I'm not a troll. I didn't say anything. :lol:
