I have both the LVF2 and the Clearviewer.  I don't think I will be going beyond the LX7, but the LVF2 is compatible with the GX1 so I hope it will be compatible with future GX family cameras should...

Those lenses are all comparable and all very good.  I doubt you could tell the difference between them in a blind test if the white balance is set properly.  If they were all priced the same I...

He's probably shooting for maximum depth of field.  Diffraction isn't as big a deal as out of focus unless you are really viewing large.

If it were my mother, I would sell the lenses and go native NEX.  On a NEX or any of the smaller Alphas, the lenses would be an effective 75mm and 120-300mm due to the 1.5x crop.  The 75mm is...

The lens makes some difference but it mostly does a pretty god job of getting things in focus.  Set the drive mode to Continuous shooting so it refocuses between shots and blaze away.  Without the...

Does it work better if you swap positions of the red vase and the GPS, or maybe even just turn the GPS around so you're looking at the back, and then try exactly the same thing?  You could also try...

The 100 macro is not conclusive for a test like this.  Almost anything else would be more confidence inspiring.

I snapped my new (used)300mm lens on to my brand-news A-77 and went out into the back yard to try it out.  The AF snapped right into close targets, then distant targets, then medium targets, then...

http://www.dpreview.com/forums/post/51327736 You might want to contact the OP.  He never did get back to the thread with a resolution but he did seem to quit complaining.

As an afterthought, I shot the same setup with my 70-300 Sigma.  It is not directly comparable with the previous post (and not completely fair to the lens) because of the changed lighting...

Here are some results from backyard tests of my longer lenses The setup - 70 feet This is the basic target.  ~ 70 feet shot from a tripod with NEX-7, manual focus Tokina AT-X 300 f/4 Tokina 300...

Marc, an interesting article if you haven't seen it before http://www.rokkorfiles.com/100-300mm.htm While this is talking (I think) about a manual focus MD mount I think the optical formula is the...

I have had two copies of the Minolta 100-300 (APO and non-APO) and I currently on a Sigma 70-300mm DG OS which seems to be rated more or less equivalent to the Tamron.  Wide open, the Minolta and...

This is a very good Minolta lens that doesn't get very much press.  It's best feature is probably it's optical performance vs. it's size/weight.  It was the 'long' lens that always ended up in my...

I had both models of the 100-300mm.  The APO handled certain lighting conditions better than the non-APO model but not as many as you might think.  As noted above, my 100-300(APO) was slow to focus...

Seems like you're talking about two different lenses.  16-50mm better if you need to shoot at f/2.8 - 16-80mm certainly better if you want to shoot between 51-80mm.  f/4 and above between 16-50mm I...

Because most second-hand cars aren't sharp at f/4 ??

If they can do it well for Rokker MC/MD.  I'd also like Contax G but I think I saw something that there wasn't enough space for the required compression lens.
