Excuse me for possibly raising a point which has been raised before in this thread, but which 200+mm zoom is considered to be the fastest focusing and sharpest lens on the original K-5 (&/or the K-30 as I have both)?

FWIW, my main interest is air-show shooting and I already have a non-HSM/OS Sigma 70-200 (not used much recently), a Sigma 100-300 F4.0 (used a lot since getting it) and a Sigma 150-500 HSM OS (not yet used much at all), and would be ready to sell one or two of these if an improvement could be made. (BTW, I also have the Sigma 1.4 Ex (used a lot with the shorter Sigmas) and a Kenko 1.5 Pz SHQ TC. which can be used).

Thanks in advance.

John

I should perhaps have added that in the middle of last summer I suffered a very painful herniated disk in my spine, and was not able to do much all - but acquired the 150-500 later in the year when a "too good to miss" opportunity came up on the UK Pentax User forum. However I never got a chance to "use it in anger" then and so I am trying to get myself straight for the coming summer's shows and so on, as I certainly can't carry all 3 lenses around with me (I suspect that one at a time will be the maximum my back will now take).

my DA 70-300 is fixed...courtesy of Pentax Japan ...some test shots below (wasn't any good surf today)
Is there such a lens as a Pentax DA 70 - 300?? Sigma and Tamron has this range ie. 70-300 f4-5.6 Macro.
And Pentax has the DA 55 - 300 in different variants including the new HD WR lens.
Regards.

Thanks, but, unfortunately I already have a DA 55-300 and it focuses too slowly/uncertainly for air-show use (I have tried ), the Sigma 70-300 (non-APO version, admittedly) that I checked against my 55-300 was definitely less sharp at the 300 end during a comparison before I bought the latter, and I have read of fringing issues with the equivalent Tamron (and I don't want to do any more post-processing than I can absolutely avoid, so fixing in software is not a preferred option).

The Pentax DA 60-250 is probably too short as I regularly used the 100-300 F4 at 200mm+ with the 1.4x TC, and so I think that leaves the choice between the two longer Sigmas - or possibly the 80-400 Tamron which is reputedly to be comparatively light for such a long lens?

John

PS: and I don't think there is a DA 70-300!

Long time no pictures. Very warm winter up here in Finland this year, but today it snowed almost for the first time. Our U19 team had a training match agaist our U17 team and after a bit of a break I was there with my K-5 and Tamron 70-200 f2.8.


The snowing was making things a bit difficult at times







In these kind of conditions it's quite hard to get the focus right with the K-5 and I've been thinking of an upgrade for quite a while. Don't know if it's going to be K-3 or something else, but the K-5 is going to retire soon. I'll probably give it to my daughter or keep it as a spare, we'll see.

Nice set. I'm sure the snow & low contrast light made focusing difficult but they're good sport shots in my book.

You might be better off with the F/FA 300/4.5, or the DA*300. I think the older ones are slightly better, but the DA* is close (in IQ and AF speed) and is also 1/3 stop faster, plus it has WR. Being primes, they're relatively light in addition to having high IQ. I think cropping is an easy edit, and since they're sharp you should be covered when e.g. 400mm would have been more "ideal."

For AF speed at 200mm avoid the DA*200 (much slower AF than the DA*300, for some reason) and opt for an FA*200 or the very latest (current) Sigma 70-200 OS you don't have.


Also note that others have remarked that the DA55-300 is not really as long as a 300mm prime in practice (not to mention the diminishing IQ over about 135mm). Same goes for the DA*60-250, I believe - often not much longer than a 200mm prime, in practice.

Thanks, and I take your point about the IQ of the Primes, but I am afraid that I still strongly believe that zooms are the better bet for the type of shooting in question for framing reasons (you often need to rapidly widen the field of view as planes approach quickly), and where heavy cropping is not really viable and especially on the K-5 as compared with the K-3's more densely packed sensor.

Also, whilst I don't have the Sigma 70-200 OS version (out of my price bracket!) I do have the original EX DG non-OS version which is very good at relatively close ranges (for airshows, that is!) but the amount of cropping required for shots at long distances causes too much image degradation to be a viable option most of the time.

BTW, FWIW my early 55-300 is amazingly sharp at the 300mm end (shots to prove it ), but, as we know, it's far too slow to focus on most fast moving objects unless these are a good distance away and moving at right-angles to the camera.

I can see how the zoom might still be desirable in this case.

Interesting - my early DA 55-300 also shot images that looked fine at 300mm. But I eventually realized that not a single image over around 135mm had enough visual impact to grab my attention. So I effectively had a 55-135mm lens. This is when I decided to sell it and find a used DA*50-135 for a good price - a lens which is outstanding throughout the 50-135mm range. But of course I'm not recommending it for your application - not only is it too short, it focuses too slowly (which is why I use fast focusing primes - FA*85, FA135, and F*300 - for sports).

Since you're outdoors in the daylight, you should look at the Tokina 80-400. I'm not sure of the AF speed, but the images from this lens are nice.

Here are a few shots from a game last week. I believe all of these are with the Sigma 70-200. I took some shots with a 28-70 as well. Also used the 540 flash.

Things have slowed down here since the K-3 hit but I had a (basket) ball with the K-5 & K-5IIs this season.

Trying to raise funds for the K-3 but still going strong (?) with the K-5 Classic.

My daughter is in her senior year of high school and won't be participating in intercollegiate sports in college so my career in sports photography is winding down. I'm not sure the K-3 is a no brainer preference over the K-5 (or K-5IIs) though. Especially when taking a lot (200+) of photos/game and/or in bad light for web-posting purposes, I think the K-5 cameras have some distinct advantages.

@GvilleRick, @dadiPentak: Great shots, especially in a gym! Are you actually on the gym floor or are these cropped? I have a DA* 60-250, just purchased a K-3. I do think the K-3 is worth the upgrade; just an opinion. (I got a really good 'open-box' deal.) Do you think the extra stop (f2.8 to f4.0) is a significant difference when shooting in a gym/low-light environment? I feel the shots I'm getting are pretty good BUT grainy due to the high ISOs I end up shooting. (Settings: 1/500 @f4.0, ISO variable) Thanks!
