At the price mentioned, I suspect you're talking about the non-APO version of the Sigma 70-300. If so, you'll be dealing with significant purple fringing and softness at the long end. I doubt that anyone familiar with these lenses would vote for the non-APO Sigma.

The best value IMO if you want the 300mm range is to the get the two lens kit with DA L 55-300mm (I own a DA 55-300mm and a Tamron 70-300mm Di).
Hi

Thanks for your reply, but K-r does not come in twin lens kit with 55-300mm,

Are you sure? It does in North America. The whole point of releasing the DA L version was to offer it in kit form.

I would try the Pentax distributor, see what he has to say about the DA L 55-300. Assuming that's your interest.

Pentax left, Sigma right.


Ditto.


Pentax top.


Pentax top (?).


Sigma (handheld)


End (literally) of the Sigma. (it's still on my shelf).


After getting the Pentax 55-300 I never used either lens again. I subsequently traded the 50-200 toward something else.

Great photos above, especially the bee & the flower. Very sharp for handheld! What I was really after was an all-in-one lens. Yes, I know that's not really how DSLRs work, but I'd love to be able to go out an not have to change lenses between shooting flowers/insects and telephoto range.

Here's the Sigma I'm looking at:

Sigma 70-300mm f4-5.6 Macro DG Lens For Pentax Digital: Amazon.co.uk: Electronics

Many thanks!

That is the weakest of the various telephotos that have been mentioned in this thread. Because it is non APO, it has severe purple fringing and is soft at the long end. The APO version of the Sigma has very low pf, but is more pricey. I would recommend the Tamron 70-300 or Pentax 50-200 instead. The Tamron will be sharper but also suffers pf, the Pentax shows better colours and is not as tele. The Tamron has a 1:2 macro feature, but 1:2 is marginal for insects (need to crop the photo). Either lens has enough magnification for flower heads. If you really want the 300mm reach, the Tamron pf is a pretty decent lens. Here's a set I did when I was using it, before I bought the Pentax 55-300mm.

Hi there

Is this the Tamron you'd recommend:

Tamron 70-300mm F4-5.6 Di LD Macro - Pentax Fit - Only 119.00 - SRS Microsystems

Thanks!

Yes, that's the current digital version. There is an older LG lens that was horrible for pf on digital cameras.

That Tamron is an awesome lens for the price - you'd have to pay twice as much to get anything better*. Just my opinion, obviously.
For the best sharpness, stay under about 220mm and stop down to around F8. Fully open at 300mm it's soft but it'll let you take shots you couldn't otherwise.

200mm F8
300mm F5.6
300mm F14

*Actually, upon checking, not strictly true. You'd have to buy a lens hood for it, but the DA-L 55-300 can be had for 170 here at the moment.

The big advantage of the Pentax 50-200mm is that it is VERY small, you can easily slip it into a pocket if your going out for a walk and want something light to go with your wide angle.

I don't think it is good enough to be your primary long lens (my normal kit has the 50-150mm f2.8 in its place), but it definitely has its advantages.

However I don't think the Tamron gives enough of an advantage to justify the extra money as I would save that and put it towards a good long lens.

I think all of these lenses can perform well in the right situation. They need to be stopped down a little to achieve good sharpness, which is often tough to do at 300 mm when your maximum aperture is 5.6 already. The 50-200 gives no benefit over the other lenses mentioned, except maybe a little better resistance to flare and a little less PF.

I personally really like the DA 55-300. The benefit of this lens has to do with the colors and contrast. I had an old Sigma 70-300 and found it really soft at the 300mm end and it had really poor contrast and tendency to flare. I think they have gotten better, but you still get what you pay for.

Not in the UK. UK stock is only 50-200.
Clifton cameras and Bristol Cameras both do the 55-300mm as part of K-x Kit... They also stock K-r... Have a chat...
Camerabox too... There's loads about!!

The K-x is being sold all over the uk with 55-300mm lens as part of a 'twin lens deal'... Seams they're pairing the K-r with the 50-200mm (like they did with the K-x when I bought mine)
At the time I didn't know any better... Have a chat with a store manager (or 10)... I reckon you'll be able to sort something out.
