Airshow lens choice
I'm a 3 year pentax user and have progressed from a K-X to a K30 in that time. I have the kit 18-55 WR and the 55-300 lens and am now looking to expand my lens collection with a focus towards long lenses for airshows. I find the 300 okay but would like longer reach and seem to have settled on ...

Airshow lens choice
I went to RIAT2013 a week back and took my Sigma 170-500mm. It was ideal for some shots but too long at the short end for others, so I made use of the 55-200 Pentax as well. As JohnA mentions, at 500mm lenses take no prisoners! An awful lot will depend on where you put yourself to watch the displ...

Airshow lens choice
I too was at the excellent Duxford Flying Legends show and was using a 55-300 and 18-135. Focus hunting with the 55-300 was an issue for me and I concluded that photographing flying planes takes practice and patience. If you are planning to spend serious money and air shows are to be your thing, ...

Airshow lens choice
Unless the 150-500 or 120-400 is significantly sharper than the 50-500, then I think I have my answer. At Duxford and other places I've found I need the 55mm on my 300 for when stuff taxis past. It saves me from having to swap lenslenses rry a second camera. At Duxford and shuttleworth, formatio...

SMC M 135mm f/3.5
Was trying it out in the garden and soon found my limitations of hand holding and trying to keep sharp focus :roll: I'll have to try it out at all the settings using a tripod. Might be a handy size for doing a sparrow/starling/pigeon watch. Wonder how it will perform on the K3 :lol:

SMC M 135mm f/3.5
Should be worth the GDP of a small country when the Ricoh AS-IF full frame comes out and drives up prices of 28mm, 50mm and 135mm lenses :shock: :wink: 300mm is really the minimum for birds on APS-C :cry: The 135mm f/3.5 doesn't focus very close either. '

Mid to Long Telephoto
until late this year when I managed to snag a bigma, the DA L 55-300 was my lens for airshows and it did well. it hunted a bit due to the low contrast of sky etc but got some great shots. you can't go far wrong with a 55-300, if you can stretch to the DA, get it over the DA L as it has the m...

Upgrading from the 18-55 Kit Lens
My kit currently is a 15mm DA, a 18 -135 DA WR (designed for the K5) as John and the 55 - 300 DA. Around £375 used? The 15mm DA is extraordinary for landscapes especially its into the sun flare resistance when stopped down and colour rendering. Not cheap but tiny gem you can hide in a pocket.£299...

Upgrading from the 18-55 Kit Lens
I had the same quandary earlier this year. Was set on one of the 17-70 lenses but ended up with the Tamron 17-50. So glad i did, it's razor sharp and i could see the benefit over the kit lens straight away. Having F2.8 through the range is a huge bonus. Has a useful 270mm close focus and excellent m...

Tamron 17-50 2.8 to avoid?
IIRC there were a few people that have reported duff copies (soft edges or sharper one side). This was a while back but there is no way of knowing if you have one until you have take n pictures with it. Only real way to be safe is buy from a retailer rather than Ebay.

zoom 300mm lens choice
having talked big lenses for airshows I'm just going to have to face that I can't afford a sigma for a while, cry into my cuppa and leave it at that. so casting round I still also have to face the fact that the Pentax DA 55-300 lens while delivering a nice picture in good light, hunts like a dog ...

zoom 300mm lens choice
I'll consider anything RobE17. It turns out the 55-300 I have is the DA L version so it lacks the quickshift, that and probably poor technique accounts for why mine hunts more than it probably should. I'll consider 70-330. I'll consider 100-300. I've also flirted with the thought of the cosina 10...

zoom 300mm lens choice
All the usual suspects are covered but i found the Sigma DG 70-300 was faster to focus and hunted less than the 55-300. But like the Tamron Di LD 70-300, it was soft beyond 250mm. There's no cheap option 300mm zoom that ticks all the boxes. Well except the Tamron 70-300 VC but they don't do a Pentax...

The 55-300mm works very well with a TC. :lol: This was at about 280mm + TC Handheld K-5 200ISO Edit: Just noticed you have the 55-300mm that hasn't got Quickshift, in which case I would change the lens first for the more expensive version otherwise it huns for focus quite a bit. It's be...

so what is the name of the pentax 55-300 with quickshift because that is my one gripe with my existing DA L 55-300 ED, it hunts......a lot. for airshows I want a fast 300 lens to get round that, sometimes the 55-300 I have just hunts and I have to zoom right back to 55 to re-acquire and have it l...

for airshows I want a fast 300 lens to get round that, sometimes the 55-300 I have just hunts and I have to zoom right back to 55 to re-acquire and have it lock in. According to that is all down to user error and not the lens. Using a teleconverter on the 55-300mm will make the AF a whole l...

Just checked with my 55-300mm. If I just point it at something at 300mm and the image is very blurry and I can't make out what the image is... the camera can't either so it defaults to winding in to 4.6M and then back out again towards INF until it hits something in focus. It's not hunting just ...

what unholy combination of adaptors do you have to use to make a Canon adaptor work with the DA55-300 with AF?? I salute your ingenuity! Pentax AF has always had a tendancy to "get there in the end" even operating well outside its specs, where Canon tends to be faster within spec but be artificia...
