A simple question about ‘muscle memory’
Insightful all, thank you. I thought johnriley's point was well made, practice practice, practice. I also liked 1stEverPentax's comment. That resonated. QFI's are definitely a 'different breed'. I remember one of my instructors at Middle Wallop, he was called the 'Mad Pole'. He would sit be...

. . . I'm considering changing to Micro 4/3rds (MFT) kit. Why shouldn't I, can you talk me out of it? I've used Pentax kit exclusively since the 80's, I have a collection of 5 DSLR bodies (K20D, K-5, K-5 II, and 2 X K-3 II all with grips or L-Bracket) and more lenses than I ever use ranging from ...

OK, I appreciate your comments. Firstly, I have never considered myself to be 'Old'. Instead, I acknowledge the fact that my body's condition will not allow me to enjoy certain aspects of my lifestyle as I once did. EG, today I stepped up onto my terrace after getting my washing in and my knee gave ...

I think you should do whatever you want to do, but there are a few things to look out for. I would really check out what you are contemplating moving to. Is the grass greener? Maybe, maybe not. If it ends up a not it could be expensive. Pentax have lots of compact lenses. Some mirrorless cameras ...

Hi Mannesty , Have you taken into consideration, the camera bag or camera backpack Thanks for your comment. I'm well sorted on the bag front thanks. I have 2 x Tamrac Expedition 7X bags, 1 with my Macro kit, the other is in storage. I also have a Lowepro Vertex 100AW, which I love, and a Lowepro Fa...

I wonder why you are getting rid of some really nice lightweight primes and keeping the heavier zooms? Good point, but . . . I'm just not using the primes; I much prefer the ability to frame a shot with a zoom lens rather than cropping in post. I did a weekend trip to Valencia a few years ago an...

have ventured into M4/3rds with OM-D E-M10 mk2 plus 4 lenses , just everyday ones . 40-150 f4-5.6 nice sharp lens, 25mm f1.8 same, 45 f1.8 really good , bit of a sleeper lens and 14-42 kit lens . Tried a couple PL cameras in the past but found them too small. My findings so far are that Pentax win...

Hi Mannesty, If you want some more info or questions asking about the Olympus kit then let me know. I only have the EM-1 ii and 40-150 2.8 Pro so can't comment on the other stuff. I'm doing the opposite and switching back to DSLR's from Mirrorless. Oly stuff is getting sold. Still deciding be...

The grass always seems greener on the other side so I'd recommend trying out other equipment before buying or selling. Some things are easily adapted to, such as zooming direction etc, others are simply worse, and you may find that a lot of things you take for granted with your Pentax gear is far...

Thank you all so much for your comments last year, I thought I would update you all with my decision. I have a large collection of quality Pentax lenses, ten in all, a mix of primes and zooms. I also have 3 Sigma EX DG lenses, the 180mm f3.5Macro, 70-200 f2.8 , and the 150-500mm. I rarely used ...

Lens diameter
I am no techie but guessing several reasons: lenses need to incorporate electronic motors to drive focus, to help edge to edge sharpness, to facilitate wider f-stops like f1.4. Another reason could be that lenses need to match the performance of high pixel count sensors.

Lens diameter
It's a good question and as stub points out, it isn't just a matter of speed of lens or the need to squeeze in AF motors etc. The Pentax D-FA 100mm macro takes 49mm filters. The Sigma 105mm EX macro takes 58mm filters. Both are FF, screw-drive lenses. And then there is the Irix 150mm macro. Still FF...

Lens diameter
Lenses today have more elements to better control chromatic aberration, edge sharpness, finer details and, especially for zoom lenses, distortion. Adding those elements make the lens longer. On those longer lenses for a given focal length, the entrance pupil is situated further back in relation to...

Live View AF K3ii
Thanks, the reason for the question was my new(to me)Tamron 70-200mm f2.8 seemed to focus more accurately in standard AF than LV even with focus peaking but sat down today and did some searching which ended up full camera reset with lens fitted , all now seems ok. A nice sharp lens

Live View AF K3ii
The K-70 had on sensor phase detection sensors, but I'm not sure of any other pentax cameras with this. That leaves you with contrast detection only in live view. Enabling focus peaking is only for assistance during live view manual focussing, it won't help AF performance in any way.

New Ricoh GR IIIx
This new model will probably do well as it offers an option to the Griii albeit I suspect forking out an additional £700 odd pounds may put current owners off!! The Griii is an exceptional compact camera with an impressive lens and specs. One of the usual negatives mentioned is battery life. Perso...

Decent cheap trail camera
Can I ask - do you set the flash on these cameras? I'd expect the IR lens still needs an IR light source - I ask as I know some animals can see into IR wavelength and worry I'll startle them, might be the wavelength is still out of visible spectrum. The things I've got are stand-alone, all-in-one ...
