Ran another test, this time with the Oly 17/1.8. No tube, closest focus distance subject to sensor about 165 mm. Size of ruler in the mft sensor (17 mm wide) was about 125 mm. So this was around...

On the other hand, the 26mm tube increased magnification by 70%.  And the 86mm focal length is 30% longer than 60mm.  Hmmm...

I've some numbers from using the tubes on my Oly 60 macro (also reported at http://www.dpreview.com/forums/post/51450718). Without the tubes, the ruler in the photo showed 17mm side to side. So...

For macro, the PL45 is an excellent lens, no problem there. For wider angle than the 12-42 you already own, I don't know that the Oly 9-18 will earn its keep.  I've run the Panny G series,...

Not a 14 mm tube, its 16 mm, of course...! Measuring consistency of tube length, micrometer screw gauge, repeatability plus/minus 0.01 mm, four points around the circumference on or around the four...

Just took delivery of the FOTGA 10mm and 14 mm tubes off eBay, thought I'd post some findings. The tubes are very light, a combination of aluminium mating surfaces and plastic barrels.  The lock...

Hi Bill Would you have then enthusiasm to profile the strengths of each book?  I'm looking to buy one and that'd help me match an appropriate book to my weaknesses... (smile)  Heck, your profiles...

I run the Oly 4/3s 14-54 and 50-200 on my E-M5 with the Oly MMF-3 adaptor.  Excellent glass, excellent IQ, great value, weather-sealed.  Slow to focus, forget action shots, but focus (almost!)...

The Prius Hybrid doesn't run for long just on the battery, and certainly nowhere near one hour. My Prius (3rd generation) will flatten its battery after around 4 minutes with electric-only power at...

The heads-up is helpful, but not too sure about the blame... We've got used to what other manufacturers decided was good for us -- bang it on auto, no need to think about the camera any more.  It...

Those nice folks at LENSMATE also do a neat adaptor for the RX100.

Nice analysis, I'd forgotten about the dreaded swelling in the body problem...  The RX100 user manual tells me to expect the in-camera battery charge to take around 155 minutes; given the 1240 mAh...

Wow, LS, touched a nerve there, did I?  Blanking the T contact proves nothing from your list (not that I claimed it did).  But it does show that the camera doesn't need the T contact, either to...

Hi Ron, great experiments, thanks!  Inspired me to see if the T contact was needed at all... So I taped a tiny patch of low tack masking tape over the contact on the (Sony original) battery,...

My mistake, I got it into my head that the NP-BX1 was a two-cell battery, when it isn't!  Argh!  I guess the good news is that makes 3rd party batteries and chargers somewhat more attractive...

Also new to the RX100, also keen to know if others have found good 3rd party solutions for batteries and chargers... AFAIK, a "proper" charger has three points of connection to a two-cell Lithium...

My better half is as right-handed as me, but automatically puts the camera to her left eye. She is "creative", I'm the geek...  So she also can't get on with the E-M5 grip, just a catastrophe for...

In addition to native mfts (17/1.8, PL 25/1.4, 12-50 kit, 60 macro) I run the original 4/3rds 14-54 and 50-200 on my E-M5.  IQ terrific, focus speed slow -- maybe 1 sec if it is in the vicinity,...

Hi Peter, just before we hit the magic 150 posts, I'd be interested to read your summary of what we've learned about the noise you see.  Not so much about the various advices to open your aperture,...
