Hi gents.

In the specifications for my Sony NEX-7 are two statements with regard to the viewfinder magnification:

Viewfinder Magnification (35mm equivalent):

0.73x

Viewfinder Magnification (nominal/claimed):

1.09x

 

Could somebody tell me why there are two data and what is the difference between „35mm equivalent“ and „nominal/claimed“? I know that the crop factor is 1.5 and if you multiply it with 0.73 you get 1.09. But how useful is this info? I mean it is the viewfinder, not the lens.

If I wanna do some math, do I have to go with the factor 0.73 or 1.09?

Any input is highly appreciated.

Thank’s and stay healthy.

GMichel

      2 Primes or 1 Zoom?

      By XKAES · Posted

      I'd opt for a small zoom, but I must admit that there seems to be a dearth of lenses in the e-mount in the 24-50mm range -- for some reason.  I have a small 24-70mm, but that's an a-mount Tamron.  Maybe you can find something by looking at lenses slightly longer.  I have a heavy, but small 24-100mm a-mount, and Tokina made a 24-200mm a-mount.  Maybe there are similar lenses in the e-mount.  Kill three birds with one stone.

      Well this! Thank you! I have been following suggestion after suggestion for the past 3 hours with my a7CR and never thought of removing the battery. Magic!

      2 Primes or 1 Zoom?

      By bs.shoots · Posted

      I recently got an a7cii and to pair with the compact body, I thought of getting 2 of the trio compact lenses, 24mm F2.8 and 40mm F4.0. (I already have a 70-200mm) However I stumbled upon the newly released 24-50mm F2.8 G. I'm not sure which to get - I like the small factor of the prime lenses ON the body because it's discreet and helps me blend in as an average tourist / doesn't make it obvious when doing street. But if I add the dimensions of the 2 primes together, it takes up more space in the bag than the zoom lens. BUT THEN, the weight of the 2 prime lenses is 110g lesser than the zoom lens. The zoom lens has the added benefit of being more versatile.   So now I'm stumped. Each has their pros and cons and I can't decide which to get. I'd like to hear the views of you guys who are more experts at this.   Edit: I'm a bit concerned about weight because the last time I went overseas my shoulders were aching from carrying too much. Which is why I was looking for small compact primes in the first place.
