Witch lens?

Ok guys, I'm pretty new on the forum but it look like a great place What I would like to do with my K200D is to shoot some aircraft at ground or in flight. So I need a big lens, I actually have a 55-250 but she is to dark I have to set to long aperture to have decent light in photo but you know...plane move fast so...I don't really know what lens in what size and what brand to look at so I ask here! hope you guys can help me!

Thx

you can look it up here: Pentax Lens Review Database - Main Index

search for 300, 400 etc. will give you the lens for that focal length.
check the ratings and the price and take your call.

one more thing: edit the thread title. it is misleading

Aircrafts? You need the biggest lens you can afford.

I think a Sigma 150-500mm F/5-6.3 APO HSM is a good choice.

I had two 300mm F/4 lenses but I found them not long enough. When I added a Pentax 1.7X AFA to make it a 510mm, the image quality is inferior to that of the Sigma 150-500mm.

Also, with a zoom lens, it's easy to "find" the plane in flight with the lens at shortest FL, then zooming in for the photo. With a 500mm fixed focal lens, it's difficult to find the plane in the sky.

BTW, where did you find your 55-250? I've never heard of it.

Perhaps, but if the lens he has now is not fast enough it is highly doubtful an [I]f[I]5 would be a better choice.

I know. There must be faster and longer lenses than the Sigma 150-500mm or 50-500mm.

But I'm not sure the OP is ready to mortgage his house.....

I mean 55-200, the lens that come with the K200.

I was about to spend 1300 to 1500. I know that good lens can have incredible price but now my skill level isn't enough to spend to much on a lens only.

I gotta say, when the OP's subject was a "witch" lens, and the proximity of this question to Haloween here in the US, and then the talk of "aircraft", well...I just wondered how much lens does it take to shoot a broom????

I don't know if Mighty Mike hangs around at all, but he shoots a lot of airplane photographs. Wonder what he uses?

A lot of shooting airplanes is learning good technique. Learning how to pan, as well as having a long enough lens are key factors to good photos.

Does anyone think the OP could maybe spend some of that money on a camera body that can run at a bit higher ISO, for this purpose, rather than a bigger, faster lens? It's usually pretty bright up there.

Another idea I'm inclined to want to suggest is an old Tokina AT-X 80-200 2.8. They aren't too bad, pricewise, are really nice, and probably autofocus isn't something that you need for that kind of work. On crop they would probably be of a decent length for low-flying aircraft, too, while giving that spotting advantage of a zoom lens. They were always considered nice and sharp for a zoom, too.

Going up to like a K20d might help, and there's some extra MP for cropping purposes, which can make up for a bit, FOVwise. K-7's seem to have nice high-ISO, too, if that's really needed.

Hi.

I have been using two lenses for a few years. The first is the Pentax DA 16-45mm f4.0 which I use for ground shots. When I switch to photographing aerial displays, I used to use the Pentax FA 80-320mm f4.5-5.6. It served me very well for a number of years even before the move to digital. I found the image quality above 260mm was soft, so I remained below that, but at f8 and f11 the pictures were so much better than wide open.

A few months back I bought the Pentax DA* 60-250mm f4 to replace this lens. It really is a great lens (but really pricey). The other option I was considering is the Sigma 100-300mm f4, but this lens is 400g heavier than the Pentax DA*.

Anyway, some pics I took with the FA 80-320mm are as follows:

1. F-22A Raptor Air Superiority Fighter - K20D - 153mm, f5.6, 1/1000s, ISO 100.

2. Boeing Stearman Biplane - K10D - 200mm, f8, 1/750s, ISO 100.

3. Martin Mars Waterbomber - K10D - 118mm, f5.6, 1/250s, ISO 200.


It's been a real workhorse for me at a budget price. I'm hesitant to go above 250-300mm because a lens with excellent image quality would cost a fortune, and there's camera movement being amplified too - doesn't help with AF.

Anyhow, it's really up to you, but that's the road I went down.

I have run across his work too, and went back looking for some of his old posts - on another board. I found them here....

Airplane Photos: Pentax SLR Talk Forum: Digital Photography Review

... as you see, he was kind enough to add the image meta information. On the images posted he is shooting at around 300mm, but note the aperture f8 with ISO 400.

A number of moderately priced lenses should work for you. The DA 55-300 or the FA 80-320, with out having to resort to expensive primes as of yet.
