Can the K3.3 focus on anything in the air (not just birds)
And the lens that enabled the K3iii to do it was...?? Steve My favorite Pentax masterpiece - F4 300 DA*

Not quite as small as your midges, but had good success with the K3iii, my 150 - 450 seems to be welded to the camera at the mo Dragonflies in flight Otters B52's U2's

Fabulous set Chris ; the Dragonfly is particularly stunning; can’t beat Pentax glass and now we truly have a premium action /wildlife camera in the K3.3.

Great shots guys. That B-52 looks like it has been fitted with the latest in defensive aids...a smokescreen. There will be calls to ban those on purely environmental grounds! regards Karlo

Can the K3.3 focus on anything in the air (not just birds)
Just having a play in the garden in the excellent warm weather with the K3iii and the 150 - 450. Hoverfly in flight, they don't stay still at all and change direction faster than a typhoon jet Hand held, manual focus ISO 400 - 1/800 sec - F7.1 plus a decent crop - equiv FL of 510mm

Can the K3.3 focus on anything in the air (not just birds)
That's not a hover fly, it's a bee fly! And while you're right about them changing direction impressively quickly, they can stay still for long periods when they find the right spot - usually over a warm patch or looking for a suitable hole in the ground. Nice shot by the way. Steve

Can the K3.3 focus on anything in the air (not just birds)
Super shot - the detail is superb and clearly the 150-450 is another Pentax masterpiece in the right hands. A great capture - insects in flight could become a cult thing Given they are always around

Can the K3.3 focus on anything in the air (not just birds)
These are all brilliant, and a tribute to the photographers. The 150-450mm lens is great for larger insects like butterflies as it can focus relatively close but far enough away not to disturb them, and get that beautiful soft background.

The 150-450mm lens is great for larger insects like butterflies as it can focus relatively close but far enough away not to disturb them, and get that beautiful soft background. Its pretty good for small insects as well, although finding and then keeping the critters in the viewfinder on the wing c...

Whitby Goth Weekend soon
We're planning on being there on the Saturday. Then hopefully we can meet. I'll be there on Saturday and possibly for an hour or two on Sunday as I'm off back down to Essex (via Whitby?) Best regards

Trying out some focus-stacking
Dandelion seed-heads are beautiful if one looks carefully before binning them. I threw away two, then saved this less-than-perfect one to try out some focus stacking. Robert L. stacked 17 frames for his 'Look what I pulled out of the border' (30 April) but only 6 for his earlier goats-beard seed hea...

Trying out some focus-stacking
An interesting pair of stacks. There is indeed not much discernable difference at the image size in the thread. But click on the images and the larger versions are definitely different - the latter (13 stacked images) is much sharper across the whole seed head. But which is the better? If you wa...

... So whether it's 'the more is better' depends on what you want. As always, the technology must be the servant of the artistic vision! :wink: Steve That is a most interesting comment. As a retired scientist, with zero artistic talent, I suppose I was looking for maximum detail. Fuzziness upsets...

Trying out some focus-stacking
One aspect of focus stacking I have never found a satisfactory answer to is that the subject changes in size within the frame as you focus from front to back, whether you are moving the front of the lens or the whole camera body. The only way I can think is if a macro lens has internal focusing and ...

That is a most interesting comment. As a retired scientist, with zero artistic talent, I suppose I was looking for maximum detail. Fuzziness upsets me :D I used to be a scientist, too. Then drifted into engineering circles and discovered 'engineering judgement'. Never did find out what it meant, oth...

Trying out some focus-stacking
Combine ZP takes account of the relative size 'problem' and resizes the entire batch to uniform dimension before combining them. The only problem I find with it is that the edges tend to be a bit ragged so it is as well to allow a bit of 'waste' around the edge of the images so you can crop it off a...

K-3 iii = Think I'm falling in love ....
Tis interesting in that it's got a proper paper manual of 132+ pages and is all in English. A lot to look at and learn :D Living in France, I bought from a store here... so, my thick manual is in French.... I read French, but not technical French.... so....errr.... I downloaded and printed the En...
