That's what I noticed when I got the D7200 when they first came out when comparing to my D7100's. Couldn't put my finger on it but liked the look from the D7200. Plus I seem to get more consistent ...

You may be confusing with the 28-70 variable aperture. That is a screw drive. The 28-70 F2.8 AFS replaced the 35-70 F2.8D which is a screw drive lens.

I have to say those shots are great. Had a chance to observe the photographer that shot my home yesterday. He used a Sony A7R2. Had the Manfrotto XPRO Geared 3-Way Pan/Tilt Head. I think that was ...

You know The Walking Dead on TV is very popular. ;)

I thought so too. But someone in the US just got one repaired 2 months ago. Another in Australia a few months back. It was mentioned the AFS motor is the same one used in the 17-35 and 70-200 VR1. ...

Actually there was a group some months ago singing the praises of the 3D affect from older AFD lenses and the flatness and dull newer lenses.

You missed the great flame wars before the D3. Canonites invaded the forum to rub our noses in the low noise pictures coming from Canon. Then after the D3, nikonians invaded their forum to return ...

I found 1/125 normally would stop speaker movement unless they suddenly move their hands which some do.  If they were still type speaker or predictable in their movements I could go to 1/60.  I ...

Only problem I have with the youtubes is the sensitivity of the mic used. The first one was showing all of the reflective sounds in the room. The D750 hits higher frequencies which carry further ...

I shoot in a church environment so having quiet shutter is of benefit. When I had the D700 it was my loudest camera. I would notice heads turn from 20 or more feet away when triggering it. The D800 ...

Guess we will find out in 7 years or so.  In the meantime I will enjoy the excellent pictures I get with them.

Of course you wouldn't have read it because of your past problems with Tamron. Sorry senior moment.

That was a good write up. The pictures were superb. You must have really wanted that 200 F2 to give that up. Hope you can get the 200-500 resolved. It can be a good lens though I only chose the ...

Sigma had a few good lenses prior to 2010. The 150 was very good. I have the 150 OS for over 3 years has been doing well. Heard the non OS version was slightly sharper but that's okay it is at ...

Would have helped if you had started with these to support your concerns. Send these in with the lens.  If the Techs are worth their salt they should recognize it. I am curious what they are using ...

Nothing wrong with being fussy but I remembered you had had problems before. On another note.  Were you the one that gave a lengthy description on AF tuning your Sigma 150-600 Sport?

Sorry this isn't the Sigma of old.  6 years ago I would agree with you but they have made a change this last 4 years.  You apparently haven't had one recently or you wouldn't being making blanket ...

Dug back in my earlier night shots with the D750.  Taken with a Sigma 24-105 F4OS at F4.  I use a $80 B+W clear filter with multi coating.

I have the 28-70 and it has been a great lens over the years but you do need to consider if it should need repair in the future. It is a great portrait lens because it's strength is in up close ...

When Tamron puts out the TAP version of the 24-70 is what I would like to see. They already have good optics but if they improve them with a TAP version  that would be okay with me.
