  • Yes from what I understand Helios numbered there lens not according to any 'series' but by manufacture.design So the 44 came after the 43 but one could be a cine lens and the other 35mm
  • Nice image one of my favourite MF lens But surely you mean Helios 44-2 ? the lens is 58mm f2 but it is named depending age/fit etc rather than folcal length the numering fits in the Helios line not ...
  • If your not into high cost modern classics like the da*55 but want a fast 50 then the 1.7's are to my mind the best legacy 50's Behing the da*55 the F/fa50 1.7 delivers the sharpness and bokeh I'm ...
  • It all depends on the image and personally criteria fro whats acceptable of the images above you can see the value of cmos @mid iso's Whereas the image below shows where ISO doesn't always ruin an ...
  • The k5/k3 sreries can both run of Standard AA's with the battery grip
  • The k7 is the k20d sensor but with 4 channel output allowing Video this means it niosier than the k20d but you do get the better bady design personally I woudln't go for a k7 if hi ISO mught be used. ...
  • Agreed Theses results are indicative of processing algorythms not sensor output quality. Pretty confident either camera could be made to look like the other by just tweaking Pentax's default jpeg ...
  • In general i hate to say this given the love. But you get what you pay for Tamron make  a lot of 'cheap' lens that's on paper compete optically against more expensive OEM lens Now either OEMs are ...
  • Replied in Sigma 500/4
    The Sigma protocols are only backward engineered EoS ones (hence the fails sueing from Canon) so though the mount is physically differnet any Lens designed for Canon can quickly be retro fitted ...
  • Top one is the superb sigma 77mm Macro 400 - very sharp very fast focusing low CA decent macro with limiter - modern bodies can destroy the AF gearing on worn units. the middle one is the 72mm ...
  • Depends on torque generated by the linear motor Vs weight of moving elements as to whether it would be 'better'. Just because it's impressive in a consumer zoom does not mean it'll scale to large ...
  • Well guess I may be wrong on 3rd party :) But my point on non-standard protocols still applies hence the reveres engineering required to work with it.
  • Professionally sealed equipement normaly has a very stringent maintenance program involving cleaning , lubricating and replacing seals on a 6-12 month schedule. So bear this in mind when you expect ...
  • Mm seems so this is what happens when PR excitment exceeds the technical design ... http://www.greenbot.com/article/2983435/android/dont-use-waterproof-xperia-phones-underwater-sony-says.html When ...
  • I don't disagree with your feelings ... I just dont see any commercially viable way Ricoh could apply a 1 size fits all garrentee. IP ratings are designed fro this but irrelevant of the cost ...
  • If the front element leaked you'd have a dribble not haze and it definatley would not evaporate to nothing as rain water is full of minerals and alkaline so would always leave a visible residue ...
  • Your lens is 1 not weather sealed (only the DA* series are weather sealed) you lens is 'Weather Resistant' this is a big difference as it is not implied you lens ahs any dust resistance and woudl I ...
  • Have a look at the youtube videos comparing the PLM vs the old screw. Irrelevant of IQ you woudlnt want the screw drive lens ove the linear motor driven variant. Technology wise the 55-300 PLM has ...
  • Thats a good point - though Sigma had a number of cheap offerings 170-500 , 120-400 etc etc I guess they didn't sell well enough to continue the lines (all mounts). My most used long setup is ...
  • With the re-introduction of a FF body it might be feasable to re-manafacter the FA600 F4 but this would be the step up from the da560 and woudl guess would be above £5000. So those looking for ...
