Testing my 500mm Tamron Mirror
Problem is, there seems to be a prevailing attitude in some very noisy quarters that mirror lenses are always useless. I was recently given a Makinon 500mm f8. My assessment would be "Not too bad". Cropped shots from my 50-135mm are possibly better but that's comparing a £640 lens with something...

Testing my 500mm Tamron Mirror
Incidentally, one trick I used to deal with the hunting for focus problem: Prefocus on the tarmac where you want to photograph the car, then keep the shutter button half pressed. When the car is in the right place, press the button. This should stop it hunting and get around any problems with slow A...

Testing my 500mm Tamron Mirror
I have the Tamron and have some respectable bird shots with it. Nevertheless I am amazed that the catch in focus or manual focus gave such good results of something moving fast towards you. I've found the hairline sensitive focus difficult unless I have time. Well done!

Lens selection for USA trip
The 18-250 is so good, I don't really see a need for *anything* else on that list except the fish. Ok, maybe throw in a small prime, but that's it. Like the 35 Macro. But the 250 does close focus so well I'm astounded. Bret

Lens selection for USA trip
Thanks for all the advice everyone, I think I'm pretty much settled on the 18-250, 10-17 and DA35 (+a small, fast prime if space allows) now. Don't miss: Land's End / Cliff House; Chinatown (Stockton St as well as Grant Ave); a bike ride through Golden Gate Park; the piers; the iconic view from ...

which lens.
Whichever kit you do bring.... a single body and 18-250 for eg... just do yourself the following favour... get a hip pack, and keep your camera on you at all times. if the hip pack is not around your waist, then it should be in your day bag/backpack... but always be wearing it, and that will reduce ...

Sigma or Tamron 17-50 2.8?
The Tamron is a good lens. My copy has no focus problems and is sharp from f/2.8, the focus ring is fine and smooth and the build quality is good, certainly better than the Pentax kit lens & equal to the older (non-OS) Sigma 18-50. The biggest problems with it are the exposure inaccuracies. Min...

quick siggy 100-300 sharpness test...
but neither of those are really realistic for the situations in which the lens will be used, i.e at a decent distance. I'm much happier now I've calibrated with -4, I can't get the focus any better than AF and at these sizes, it looks reasonable to me. Bret

Question about Tele converters ???
Well it arrived today and I think I'm going to have fun with it. It's much lighter than the 3x converter. First couple of shots - not brilliant it's going to take a bit of getting used to and I need to fashion some sort of tripod. Colorado Beetle; I know the only thing in focus is th...

Best focal length for party portraits?
I'd go with the forty.. Just because I don't have that one. I have the 35 and the 50.... the wide angle distortion perspective is minimized or exaggerated by how far you are from the subject.... so the 35 is fine for couples shots, by the time you're back far enough to get them both in, the pers...

Best focal length for party portraits?
These are with the 35mm f2.4, all wide open, of course. 35mm is not especially wide, especially on APSC - there isn't really any distortion like you would see with the 16-45mm. I know proper portrait photographers use longish lenses to 'flatter their subjects' but I don't mind a very slight exaggera...

In store testing of new lens
I've decided to replace my kit lens with a faster, wider, 2.8 zoom. I'm leaning towards the Pentax 16-50, over the Sigma 17-50 but the Tamron 17-50 is also still (just) in the running. I want to avoid any FF/BF issues so I'm going in to the store to try out the actual lenses before I buy rather ...

In store testing of new lens
I would seriously consider you buying the 16-50 in store, or at the most from a national online store. Having had all the issues I have had with my 16-50 lens, having to send a 7000kg lens via post out of my own expense, hoping it gets to canada undamaged and gets back in one piece, is a real proble...

Go to Watford I am sure Chris will be happy to help... I know a lot of people speak highly of SRS on this forum but my experiences to date have been somewhat disapointing so I'll only make the hike up to Watford if I don't find a decent copy closer to home. I would seriously consider you buying t...

In store testing of new lens
From what i've heard focus can shift over use. If you want to test the lens for focusing you need to use a tripod and something to focus on.

In store testing of new lens
I found Chiswick Camera Centre very helpful when I bought my K-x by mail order from them back in January. They are a Pentax Pro dealer but I don't know if they stock Sigma and Tamron. I would have thought Chiswick fairly easy to get to from Staines by public transport.

UWA needed, any ideas?
For various reasons I need a UWA for my K20, soon to be K5. :) Have the 12 - 24, but need to go wider, not fisheye, or corrected fisheye in software. Aperture is not important and Manual focus is OK. The important bits are good image quality; does not have to be stellar, and as wide as possible. ...

Whoa! I'm glad I pounced on it while it was still £375.00 on SRS. It's back up to £549.00 now!
