Longer lens for safari?
consider a bridge camera for this trip? the x-5 or x90 seems like it'll do what you need, take up minimal space... for the number of times I've used my sigma 400, I think I'd have been better off with a bridge camera.. nice back up camera attached to a nice telephoto lens perfect for daytime sho...

Longer lens for safari?
A 300mm f4 and 1.7x teleconverter (if you can find one) is going to be approaching the £950/1000 mark. But if you buy used then you can get all/most of that back again on your return.

But if you buy used then you can get all/most of that back again on your return. yes but these days a resale of this value can take a while. If you are lucky enough to be able to have a grand tied upin a lens then yes I would go for it he will also need something else well below 300mm I would have t...

Longer lens for safari?
South African safari? I've done Kenya, Namibia and South Africa and 300mm is the MINIMUM, trust me the animals are FAR AWAY Last year I had the D3 with 300 and 1.7 (effectively the same as a 300 on a K-5) - still some cropping was needed. This year it was the turn of the K-5 and 60-250 for th...

Longer lens for safari?
Hi Chris, this one's a bit from the leftfield and I'm not sure if you have good eyesight, but had you considered a cheap manual focus 300mm prime? You can pick quality ones up for silly money. Failing this, I would stick with the 55-300, the lightest possible option is a DA L version. Also, you...

Going to japan - buy a 70mm 2.4 now or when i get there?
You could always google.jp to get an idea of the street price in Japan. I just looked at a single online store, amazon.jp - because it's easily comparable to amazon.co.uk. They sell the DA70 for JPY37,800. The current ex rate is 127, so that's £300 near enough. Or about £100 cheaper than her...

Torn between Pentax and Chinon 50mm lenses
I've been having a lot of trouble adjusting the Beep/GreenHex signal on the Chinon 50mm f/1.9 at first it seemed OK with an adjustment of -10 plus -100 via Debug on the K-5, but it was going Beep when it wasn't even in focus.... so I'm resigned to just using the viewfinder image or LV. Probabl...

Torn between Pentax and Chinon 50mm lenses
Here's why it's very difficult to compare the sharpness of two lenses. The DOF at 100% (1:1) view is so small that if they aren't both exactly in focus at the same point the results will be meaningless. The shot of the can on the left looks sharper than the one on the right, if you look aroun...

Torn between Pentax and Chinon 50mm lenses
Indeed yes, but if you repeat a comparison between two lenses with different subjects at different distances several times - and the result is always is in favour of Lens A rather than Lens B, I think you are entitled to conclude that for the actual samples you have, Lens A is sharper than Lens B. ...

Torn between Pentax and Chinon 50mm lenses
I used to take each shot 4 times refocusing for each shot. Usually one (max.) was good from the 4 or maybe it was just better than the other 3 :oops: Now using a Eye-Fi card and a focusing rail I take a shot.. have a look... if it's near, I put masking tape on the lens to stop it moving and t...

tele converters
I have the same Vivitar 2X macro teleconverter, though mine is the PK mount and the one you are looking at is PK A. It's excellent when used with a Pentax 50mm manual prime for macro, but rubbish combined with a longer lens for extra reach. It's not a criticism of the converter, it's simply not desi...

tele converters
I've got one, and as others have said it works reasonably for macro. Despite the focusing scale suggesting it will work at infinity, mine is soft enough at long distances that focus confim will not ever light, and even my eyesight has to agree! Results with my mirror lenses have certainly proved ...

Lens confusion (again)
My wife would like a new portrait lens with quickshift. She says she is happy with what she sees through the viewfinder of her K5 with her 50mm Pentax-A she just wants to have auto focus and WR. Now after reading about focal length I'm confused :) So my question is this, what lens should I buy ...

Pentax k10d extension tubes
I have just bought a set of Hoya extension tubes to use with my 50mm 1.7 lens as a macro system, but I can't get the lens to focus. Am I doing something stupid?

Pentax k10d extension tubes
Hi Martin Probably need a bit more info. Do you mean auto-focus? Is your 50mm 1.7 a manual or autofocus lens? Do the tubes have electrical contacts or are they manual only?

Pentax k10d extension tubes
Hi Martin You shouldn't really have any problems getting focus with a M 50mm and extension tubes. As Roger says you need to be pretty close, but that's to be expected as it's macro. Only a small amount of whatever you are photographing is likely to be in focus at any time so it's sometimes har...

SMC F 35-70 a bag of primes?
I've been looking for something a little longer and preferably a little better than the 18-55mm kit lens for quite some time. After seeing DaveHolmes refer to the F35-70 as a "Bag of Primes" in another thread, I thought I'd give it a go. I manage to pick one up from SRS cheaply a week or so back a...

Question for users of more than one Sigma lens
As per another thread, I am considering buying the Sigma 70-200mm 1:2.8 DG OS HSM lens for low light motor sport use because my longest f2.8 lens is the DA* 50-135mm. I also have a Sigma 180mm macro lens as well, hence the question. If you own more than one Sigma lens and you've made AF adjustmen...
