I had this problem with my 100-400 recently and it was the screws on the lens side that had worked loose.

Understood -  the 16-35pz is still in my basic bag of 4 lenses along with the 20-70 and 100-400 GB - although its not used as much. I alternate the 24, 35, or 50mm GM primes as a 4th when I need a ...

I Have both the 16-35PZ and the 20-70 F4 in my kit - and for walkaround I find the 20-70 generally more usefull..

I have the 200-600 and the 100-400 and find I am carring the 100-400 more often now. In addition to the weigh consideration - the 100-400 can pack in a small bag, is brighter, and touch sharper and ...

I might add that my impetus for engaging in the data consolidation on my own private data server was when Google recently lost many years of email directed to my corporate email account (we use...

Ive been spending time on weekends collecting all my archives from a half dozen hard disk drives (various interfaces) and different pcs and macs. Collecting everything off old formats was the...

I had a similar situation with a dropped A7R4 that cracked a filter but everything looked ok. No marks on the body (it had a grip extension). Then a little later I noticed when shooting flat ...

I recently bought the 20-70 F4 G and gave the 24-105 to my daughter. As much as I loved my 24-105 - I much prefer the lighter weight, better balance, sharpness and 20mm option . Also much better ...

I have both - very different beasts. I carry the A1 with a 100-400 or 200-600 and the A7R5 with a 20-70. The A1's advantage is speed - image capture speed, speed of focusing, speed to calculate the ...

Reading the reviews on B&H regarding the Samyang - you get the impression there may be some QC issues as some rave and others diss the optics. Another concern would be how well these work with ...

Picking nits I would argue that 85mm on a 60mp sensor could reasonable compete with 100mm lens. The Samyang and Sigma look interesting - especially the Samyang at the $299 current price - however ...

You might want to consider the sony 85 1.8 - iits surprisingly compact - but gives you something for portraits with a big enough aperture to blur backgrounds or shoot in lower light.

I agree - the 20-70 f/4 G is now the most used lens on my A7R5.  If it was only one lens I would suggest this one.

Topaz AI Sharpen's motion deblurring is indespensible for BIF shots taken with the 200-600. Although the lens is pretty sharp - its IS (even with the A1 body) leaves much to be desired. Especially ...

I just recently looked at my 70-105 and noticed that the serial number was also coming loose - I used some clear shipping tape over it to secure it if ever needed. My 100-400 GM also has a taped ...

Totally agree...

I just got the 20-70 G F4 and its is amazing.... While I love my 24-105 - I'm handing that down to my daughter.  The 20-70 G could be the ideal one lens for travel.

Mostly the A1 for Birds...  Also have an A7R5 but still new to that.

I read "it isn't easy to see the difference" come on....

They dont even look close - the Photoshop version (which I have used) sharpens the noise which really stands out when viewing these side by...
