Should I trade my ZCO527 for Khales 540i

[Jrgasser]

I have a ZCO527 on my ATXC and recently purchased a Khales 328i for another set up and really enjoyed the LSW and felt the eyebox is better.

I haven’t had a chance to look through the 540 yet and found some forums saying the IQ on the 328 was better than the 540.

Has anyone compared the 328 and 540 or the 540 to the ZCO527? Considering trading/selling the ZCO and grabbing a 540.

I have both. Don't do it. The image is breathtaking but the mechanical problems with the dlr elevation turrets are just starting to come to light. I have had 2 540s that don't track right. I would bet a lot of others have the problem and just haven't tested for it. Everytime I look through it I wish I could keep them but I won't ever trust Kahles again.

That's really unfortunate. The K525i (non-DLR) was renowned for tracking.

I have the 525i and the 540i (non-dlr).
The 540 has better optical quality than the 525. I don't know if it's ZCO level though. The FOV is really a big deal. For me that more than makes up any difference in the quality. Only your eyes can decide. I can say I can use a little higher magnification in mirage than with the 525i.
I've not had any tracking issues at all with mine. It's mounted on AXSR in .300 PRC.
