D-FA 100mm Macro
May just be worth mentioning whilst we are on the subject of macro/extreme close ups that this is when you find out just how much dust can get onto a DSLR sensor no matter how careful you are. Because you are focussing so close and hopefully at a very small aperture to get the required DOF, the mag...

D-FA 100mm Macro
Hi My first post I have been a very very amateur photographer for over 40 years with both Pentax and Minolta – more a happy snapper with delusions really, but I ended up with a Pentax *istD with a couple of zoom lenses and a set of extension tubes Now I want a suitable prime lens for Macro work –...

D-FA 100mm Macro
Graham, First off - if you have extension tubes, then any of the old K-mount 50mm f/1.7 lenses would work very well and should be a lot sharper than any zoom. Something like the SMC-A 50mm/f1.7, or SMC-F 50mm/f1.7 or SMC-FA 50mm/f1.7. The F and FA are autofocus, while the A is manual focus. All th...

D-FA 100mm Macro
The SMC-F and SMC-FA 100mm macro lenses are astonishingly sharp. The FA version benefits from a 'brake' that makes focussing a little stiffer and stops the lens from creaping when camera and lens are mounted vertically. They both have focussing limit switches to prevent the lens focussing from infin...

D-FA 100mm Macro
Graham, As I mentioned, all the genuine Pentax SMC-A, SMC-F, SMC-FA and newer SMC-DA will all work perfectly well on the *ist-D series. Regarding 100mm vs 50mm - it depends on your needs! I find 100mm is just perfect for flowers, longer distance portraits, and the like. You see I do also have ...

D-FA 100mm Macro
Hi Graham, Since getting my 'D' a year or so ago, I've really caught the macro bug, first using a Pentax 50mm (f/1.7) with extension tubes, then getting a Sigma 105mm. The 50mm was great, and I still use it occasionally, but I much prefer using the Sigma for insects - the greater working dista...

D-FA 100mm Macro
Thanks Brian - good price. You having it delivered? I could go and pick it up for you if you want, not far for me really, and I have a friend who's moving to Edinburgh in a few weeks, she could bring it with her, unless I forgot to pass it on... :wink: No trouble, really :D Hoped to have a lo...

D-FA 100mm Macro
Daniel, The shot was taken in Spain a couple of weeks ago. We have a rambla (small stream that swells to the size of a large river every few years when it rains very heavily) near our house and they probably live, feed, and breed there. This one was out in the dry open space close to our house an...

D-FA 100mm Macro
Mike, My Sigma 70-300 APO Macro has a switch to change it to macro focussing. This switch can only be engaged at 300mm and can only be disengaged once the focus ring is outside the macro range. I don't know if I have the Super or Super II version but it will only focus in the macro range at 300mm...

D-FA 100mm Macro
Brian, It is frustrating trying to find lenses in stock - I was in Jessops on Wednesday, looking at the Sigma 10-20, and the guy said "I'll just pop downstairs, see if we've got one" and I was thinking, yeah right, save your legs. Oddly enough, they didn't, in fact they didn't have any...

D-FA 100mm Macro
Hi All Well I eventually gave up trying to locate the Sigma 180mm Macro lens, no UK or European supplier would give a definite date, B&H were a bit vague about their supply so I resolved just to go ahead and get the DFA 100mm Macro (maybe get the Sigma some time). Then there was another tw...

wideangle prime
For non-Pentax primes, the Sigma manual focus 24mm/f2.8 and 28mm/f2.8 have good reputations, as does the Tamron adaptall 24mm/f2.5.

50 - 200 DA
I bought the 50-200 today (Jessops actually had it in stock), for the money it appears to an excellent performer and just about the perfect walkabout lens. What swayed me to get this lens instead of keeping my F 70-210 (and my other FA zooms) is the ability to manually focus (as has been mentioned) ...

50 - 200 DA
Hi Daniel, Thanks for the comments, this is driving me mad. The buttons were all working as they should on my site's last incarnation and now they are as you describe. I thought it was something wrong with my flash player but obviously not. They should change colour on rollover and then work on t...

135mm lens for sale needs minor repair
Do you have an SMC Pentax 1:2.5 135mm, or a Takumar (bayonet) 1:2.5 135mm. If the former (which is a superb lens), you have a damaged sample if it is really not as good as your no-name lens. If the latter, then it has been described as: "Maybe the worst prime Pentax ever put out, in terms o...

Attn: Mac
Just trying to get in a final shot before Don spots this or John deletes the whole string as he has every right to do. George, When you bring my lens, can you bring a case of the 50yr old as well? I'd like to save on the shipping and customs if possible - you know - gotta watch the old budget ...

Wobbly 16-45mm
Most zooms, esp. AF zooms tend to have some 'wobble' when fully extended. My F35-135 is a good example but it doesn't affect the performance. If the lens is new and you think the 'wobble' is excessive, take it back and/or compare it to another one :wink:

Wobbly 16-45mm
:lol: i think this is a sign of the times and mass production especailly where the use of plastic componnents is now comman place i tend to stick with the older SMC m/a lenses as the build quality is far superior comcared with the moidern lenses you also tend to find that the zoom systems on ...

Just One Lens
Back when I used to mainly use primes I found it was the 24mm that got used the most - so that's where my vote is going.
