Originally posted by Kevriano You would be right in your assumption about the 150-450, expensive as it is, it's the only viable option for us Pentax users, given that the old 600 is rare and mega money. But, don't forget that the 150 -450 works perfectly with the 1.4 teleconverter, and it bright light especiallyears so, with no real loss in sharpness from myou experience. This is my current preferred set up. Yes, you could get some used Canon or Nikon for less though, in fact, you could buy a new body and the Sigma 150-600 for less (Pentax take note), but it's not Pentax ��
Regarding focus points. I'm not sure about other users, but I literally use single centre point focus for all wildlife shots, so all of these million point things are a waste for me anyway. There are a few of my shots with the combo on the forum.
Thanks for your response. I already have the HD DA 1.4x TC. The concern I have is whether for wildlife and bird photography I might get better tracking AF and faster AF in general using a Canon body with the Sigma 150-600 for around the same price as the Pentax lens.
I briefly used a friend's Nikon which had the same sensor as the K5 (I forget the model) but I found the multipoint AF much smarter than in the Pentax - if I had a person on the left side of the frame, it was able to identify them as the subject and focus on them rather than whatever happened to be in the middle of the frame. My Pentax cameras seem to hunt quite a lot, but I don't have enough experience with a Canikon for meaningful comparison.

For a wild bird shooting you need at least 300mm on APS-C size camera, preferably 400mm and for full frame at least 500mm - 600mm from my personal experience. For shooting in the backyard, bird feeders etc where birds are not as shy you can get away with 300mm or even shorter.
Sure. I've mostly used the DA 55-300 on Pentax, but also a 500mm mirror lens and now the DA*300 and HD DA 1.4x TC. The 55-300 is light and portable and just long enough for situations where you can get close to subject. The mirror lens was compact and portable, but manual focus and extraordinarily hard to focus with a fixed aperture, dark viewfinder image and extremely narrow DOF. The DA*300 is optically superb but painfully slow to focus and often hunts. The lack of a focus limiter and slow focus means that fast moving animals are often missed.
Quote: There are some good new lenses out there. Pentax D FA150-450mm, Sigma 500mm f/4.5, Pentax DA 560mm f/5.6. Sigma 50-500mm.
The DFA150-450 is about AUD$3,300. The Sigma 500 f4.5 is about AUD$6,700. The DA560 is also about AUD$6000. The Sigma 50-500 is about AUD$1,300 and from what I understand, no better than the DA*300 - in other words you're better off using the DA*300 and cropping than using a Sigma 50-500 at focal lengths beyond 300mm. The reviews of the Sigma 500 f4.5 all say that it's superb - but I note that it has no focus limiter.
Quote: I personally prefer prime lenses for the extra sharpness and speed. Pentax FA *600mm f/4 it is the ultimate choice if you can find one and afford it (no longer in the production) I am planning to buy Pentax DA 560mm f/5.6 next year, I like the all weather feature on that lens. I am hopping that by next year there will be more long telephoto lenses available for Pentax. but I am not holding my breath.
I could afford the FA600 (assuming there was one for sale), but I don't think I could justify the price. Gary Chalker has posted a lot of great photos from that lens. I believe that the DA560 is wonderful optically (I've seen some fabulous shots in this thread) but it's built like a telescope. It's probably a great lens if you're going to set up in a hide and you don't have to lug the gear too far from a road.
Quote: Pentax F or FA *300mm f/4, Pentax FA* 400mm f/5.6, Pentax FA *300mm f/2.8, Pentax FA * 600mm f/4, SMC Pentax-F* 250-600mm F5.6 ED [IF] (superb zoom lens) and also some very sharp prime manual focus lenses. Tamron SP AF 300mm F2.8 LD IF Sigma 400mm F5.6 APO (AF) just to name a few. The ugly truth is that if you want high quality glass long telephoto or zoom lens you have to pay some $$$$.
Unfortunately non-AF lenses are out for me since I've started wearing glasses.
Quote: Now far as the autofocus goes K-1 and K-3/(II) has plenty fast autofocus for most situation. Not quite as fast as Canon or Nikon, but you need to shoot with higher end cameras and lenses with Canon and Nikon also and that is not cheap either. There is no free lunch here.
Of course there's no free lunch, but there's a lot more lenses available for Canikon than Pentax, and at the moment my options for AF lenses with a focus limiter seems to be the DFA 150-450.
The Sigma Sports 150-600 is about AUD$1,800 and the Canon EOS 70D is about AUD$1300, total AUD$3,100. So for around the price of the DFA 150-450 I'd get a camera and lens combination which
may be better than the DFA+K3.
I had an old Promaster 70-300 (I think) lens which focussed extremely quickly, but optically it was not nearly as good as the DA 55-300. The promaster was reasonably sharp, but the colour rendition from the DA 55-300 was far superior, probably due to much better lens coatings. I've tried the DA 150-450 in Tokyo and it seemed to focus reasonably quickly and reliably, hunting much less than the DA*300 or DA 55-300. But even so the AF speed was slow compared to the Promaster. For me, over $3K on a lens is a major investment so I want to be sure that there isn't a better option for the same price.
But the point of this thread wasn't simply my hunt for a better lens than the DA*300. It was to ask others what they considered good lenses for wildlife photography. So thanks for your response - I appreciate it!
