Being a keen bird photographer i feel frustrated that i cannot buy a telephoto lens with a longer reach than 300mm from Pentax i know that a 450mm zoom is available but at 2000 pounds this is out of my price range .Can you make a 50-150mm tele lens for about 900 pounds so that i can keep my excellent Pentax Cameras

Difficult when the current Sigma and Tamron 600mm zooms are not available in Pentax mount.
I guess the one option is a second hand Sigma 150mm -500mm which gives a good performance for the money. Or I hear say that the DA*300mm works well with the 1.4x aw rear converter, that would give a bit more reach.

50-150?

Shorter than 300.

DA* 50-135 is close.

Wait for a sale from SRS. Quite often they have the 150-450mm for a lot less than 2k.

The 300mm and 1.4x is an excellent combination for birds as long as they aren't in flight but remember if you splashed out on the 150-450mm then that will also take the 1.4x well although you need reasonable light.

The Sigma 50-500mm OS is also an excellent lens if you can find one new ... Again SRS may have one.
No equipment list here but thanks for taking an interest. My Flickr

Indeed, yesterday SRS had 150-450mm at 1500 according to Camera price buster. Still a lot more than 900

Why not a used Sigma 150-500 if funds are limited. You didn't seem to struggle getting a nice shot of the willow tit

Mine might be available soon - at less than half the price of a new one - because I rarely use it (size, weight, other options)!

Must do some photos in a day or so!
K-3 II, K-3 and K-30 (now running the Hacked K-50 f/w, so it thinks it is one of those ), & some Sigma and Pentax lenses (and a lot of old 35mm gear!)

I've got a Sigma 150-500 which I'd be prepared to let go for 450 as I've been lucky enough to get hold of a
Pentax F* 300

It's easy to blame you gear and assume that a new 'magic' piece of kit will give you better results. All things being equal, It should (unless you're already optimum) but longer (probably slower & heavier) lenses require more careful handling. In many situations, you're better cropping after shooting rather than trying to get the best out of an unmanageable lens.

You don't mention if you're APS-C or FF, but 300mm on APS-C is already a 450 equivalent. Lenses this long during the film days were always serious pieces of kit (unless going for a mirror). Canon will sell you a 100-400 (with IS as you won't have SR) but it's still 2k (and is only slightly longer than 300 - less that it sounds if you're pushing the limits).

The DA*300 plus 1.4x TC is an excellent option. The DA* is a fabulous lens better than my Nikkor 300/4 which in itself fantastic.

Couple or three nice Pentax lenses out there; the 150-450 and DA* 300mm are the two I use for birding but the problem is that for anything other than large slow moving birds in flight, Pentax do not make a body that will handle small, fast flying birds and although I have quite a few decent shots taken with my current atmoury of K3, K3II and a couple of K1's, my hit rate is abysmal.

I Know by bitter experience that the lens is not the issue it is the bodies; Slow focus, poor tracking capabilty and very poor buffering make it a very hit ir miss issue.as regards small fast moving subjects.

The K3Ii Coupled with the 150-450 is the best combination in my view, but my hit rate in terms of sharply focussed images of Puffins (for instance ) at 10 metres is at best 1:12.

Recently had a session with a Nikon D500 which is a world apart; admittedly the lens was horrendously expensive but you could just track a bird and keep shooting with only 1in 20 being off par.

Reveiwing the specs of the latest Mk2 FF Pentax , whilst it does have some very interesting upgradeded featues I am afraid the changes as regards what they refer to as "hi-speed AF" are not going to get that close to the capability needed for tracking small, fast flying birds.

On the K1Mk2 the buffering performance is virtually the same as the original K1 which gets choked in seconds when shooting raw.in continuous mode.

However accepting that the Pentax FFs are not the best for "Small BIF" the uprated iso performance, shake reduction and hand held pixel shift ( in particular) are classleading as are the lenses for .

I wonder what Pentax can do with the FF replacement for the K1Mk2 ; maybe they are happy not to be catering for the specialist birding fraternity or fast action sports shooters.

To be fair, there are enough pluses in the current FF's to satisfy enthusiasts, event photographers and general wild life photographers, with great glass too, so we can't have everything I suppose.

Just wondering, are you comparing like with like...?
Was that D500 shooting raw as well?

Comparing a D500 with a K1 is probably unfair because of the file size etc but compare the actual important differences that makes the D500 an incredible BIF shooter

A realistic comparison is a D500 vs K3 ll because they are quite ' comparable" as a camera overall, each having sime unique advantages and both are APS

When you consider why the D500 is on it's own as a truly high speed action / birding camera comparing the focus systems and the buffering capability in particular shows the Nikon is immensely different and capable from the normal semi pro DSLR such as the excellent Pentax K3ll

Focus system

Number of Focus Points: D500 153. : K3 ll. 27. D500. 126 (560%) more focus points.

Number of Cross Type Focus Points: D500. 99. : K3 ll. 25. D500. 74 (396%) more cros-type

Shooting rate: D500 10.0 fps. : K3 ll. 8.3 fps. (17% faster)

Buffer ( see following comments from a recent comparison review by cameradecision.com)

The "200-frame buffer" is only in Nikon's marketing material; it is a misleading claim. If you shoot 14-bit RAW, the true buffer is 29 frames. ( this in itself is very high capability)

However, if you use a fast XQD memory card, such as a 2933x Lexar, the D500 can empty its buffer faster than you can capture images @ 10 fps.

* Hence nothing is left in the buffer.

* Thus the buffer is virtually endless.
