Pentax 150-450 F4.5-5.6 vs Sigma 500 F4.5 vs Pentax 560 F5.6
First outing with the 150-450 to blow off some steam from work :) The AF tracking seems a bit slow but it might just be me. Will do the AF fine tuning this wkend and get back with some more photos. The images are not straight off the camera.

Disaster
So last weekend my wife had my camera hanging off the back of the kids pram and the pram fell backwards and the camera struck a blow to the ground. Didn't think much of it at the time as there were now breaks or scratches, until yesterday when I went to use it....my 16-50sdm's zoom is stuck in posit...

Unfortunately no insurance. The lens is 5 years old so no warranty. I am in Italy so I have to send it to France to get it repaired I think. I read online forums where jammin at 16mm is a common problem. But the focus issue is strange. I think it may be an alignment issue after the blow it took

Just got back from Alarm Marlow via email. I ma going to send the lens to him this week for repair. He said that Pentax will charge £150 just to look at the lens basically. From what I told him it'll probably set me back £100 for repairs if it's what he thinks it is. Not bad I say

Which Lens as Upgrade From Kit Lens
I always recommend the Tamron 17-50 as the best upgrade around. It's not WR but it has great image quality, is compact and decently built. A vast improvement over any of the kit lenses or super-zooms available. One caveat - try before you buy. Mine worked great from the word go but a lot of pe...

Which Lens as Upgrade From Kit Lens
Thanks again for all the guidance. I went to a local camera shop and had a look at the WR18-135 but I was a little underwhelmed with it - TBH the guy in the shop was a patronising so and so and I ended up walking out so I probably didn't give it a fair crack! The 16-45 looks great but I was hopin...

Which Lens as Upgrade From Kit Lens
The 16-45 looks great but I was hoping for something a little more usable in lower light so it may be held back by F4; which brings me to the Tamron or the Sigma. The Tamron seem to have the edge on IQ, from what I read, and is a fair bit cheaper but I will try before I buy. I would not worry too ...

My 150-450 DFA is a bit of a dud
I have had my Pentax 150-450 for less than a month and so far I have not got beyond the testing stage, I have yet to produce a satisfactorily sharp image. I've not owned anything this long (or heavy!) before so I expected a steep learning curve. After trying every combination of tripod/hand held,...

My 150-450 DFA is a bit of a dud
The train ride might be boring but be sure to pop into Tarboush, the Lebanese Cafe/restaurant, in the lower high street pretty much opposite Waterstones. The food was to die for way back when I lived there and I am assured by friends that the quality and service are still high :)

My 150-450 DFA is a bit of a dud
Thanks Mike. I am going to give it one last chance with +10 this afternoon and if I still can't get anything approaching what was posted yesterday by truckerathome on the Your Photo section it will have to go back to SRS in the morning. I have managed to get the switch back together and operation...

My 150-450 DFA is a bit of a dud
The plus 10 lens adjustment is a huge improvement but resultant image still marginally less good than what I see in LV x10. Tried manual focus via LV and cable release also set focus well off and just shoot - tripod and cable release again. No obvious difference. Not bad but maybe could be just a...

My 150-450 DFA is a bit of a dud
This won't come as a surprise but SRS reserved me a new lens as soon as I told them I was unhappy with mine. Just as well because by the time I got there it was their last one. Swapped without a quibble and a quick test in the street suggested it was going to be a big improvement. The same cal...

My 150-450 DFA is a bit of a dud
Nice one, hopefully you will get a lot more enjoyment out of the lens now. :D Saw the price had gone back up, must have been a special offer more than a permanent reduction which is a surprise as Chris normally comes on the forum to let us know about things like that,

Disappointed with my P645 glass...
As someone who's used Pentax gear since the late 1960s, I have always had great respect for it glassware, whether for 6x7 or 35mm. A few weeks ago I bought a lovely 645D with 3 lenses and couldn't wait to get out there and start snapping. I already use the Contax 645 system, Mamiya RZ67 gear and h...

Disappointed with my P645 glass...
The focus is also different. The H1 is focussed on the white/cream wall, the 645D on the back wall. Additionally the H1 was at f/6.8 and the 645D at f/4.5 - so even the wide-open comparison may not be fair ;) The EXIF doesn't show the H1's focal length either - so it could be tricky to compare like-...

Disappointed with my P645 glass...
I think you need to learn how to focus the cameras for test shots. The stone wall at the back is very sharp on the Pentax shot and soft on the Hasselblad shot. So does that mean the Pentax wins. Also the ISO's are different 100 and 200??? Why??? The colour balance also needs to be closer. Wide...

Sigma 100-300 F4
There were 2 versions of the APO DG , the first had the same pattern on the focus ring as the original APO and the second (below) has straight vertical lines. If you look at the one SRS has it has the same pattern on the focus grip as the one from Mifsuds and is not the same as the second one on the...

Sigma 100-300 F4
Seems strange that it's back focusing with all of them. Although the one I bought the other day is in excellent condition I may send it into Sigma for a service, I know parts are near on impossible to find for the lens now so maybe a good going over will mean less problems in the future. Can y...
