Got my APM 70 45 degree today.

 

I plan to review it in some detail over the next 10-14 days or so, weather permitting, and report back here. I will compare it to other instruments of the same size category, in particular to my Vixen 70 ED and Vixen 82 (non-ED), but also to the much more expensive Highlander 82 (which is double the weight!).

 

Very first impressions:

 

- nicely finished, very compact and wonderfully light, lighter and much more compact than the Vixen, esp. since the dew shields are retractable (on the Vixen, they are not). Very easy to mount / demount, compared to heavier stuff like the Highlander (those people used to handling the 100 or even 120 APM, please ignore this remark smile.gif )

- while the Vixens looks a bit like "DIY" (two tubes, with a funny box attached into which you stick eyepieces), the APM with its smooth design looks more like a Highlander (and of course like a smallish APM 100)

- image noticeably brighter and sharper than the one of the Vixen 70 ED (tested with eps DeLite, 11mm, on grey overcast day). Positive surprise !!! (to be verified further, of course,  over the coming days and weeks)

- collimation / alignment of tubes appears impeccable, definitely up to 80x (tested with eps DeLite, 5mm), despite the fact that

- eyepiece holders are for my taste not as firm as I would like them to be, eyepieces sit a bit too loose (does not seem to affect collimation much, at least with the DeLite eps. Will see how it goes with other eyepiece models: Nagler, Vixen, Kowa!).

 

So, overall very positive first impression. I look forward to getting it out under the moon and stars.

In that last picture, why are the eyepieces sticking out like that? The barrels should go all the way into the helical focusers.

They do look very cool, much better looking than the upcoming 90° version.

No way ! This is how the DeLites look when fully inserted (they do look different than e.g. the Naglers).

Are you getting a pair of the 82s to review.....I hate being a Beta tester.

Yes I thought I would - but now I start liking the extremely compact size of the 70 ...  if I do get the 82, I may pass on the 70 or else I can I follow Matt's lead who got two models of the Docter to review and in the end kept both wink.gif

I am on the fence about 70mm or 82mm; won't buy both.

 

Will be very interested in your reviews.

Wow, never would have guessed. It still looks odd.

We really do need a review comparing the 70 and the 82 ... ;-)

Is the weight of 3.0 kg for the APM 70 accurate?

I wonder what's up with the 82 which was specified at 3.8 kg earlier but is now listed at 4.4 kg.

This had me wondering as well but i think It's because the eyeguards are fully extended.

I also received my pair of APM 70mm Apo bino's and agree with Pinac on his initial impressions.

 

With a pair of the 24mm flat field eyepieces that I bought separately, they look very sharp optically in daytime use. 

 

I plan on a comparison with the Kowa 82 soon.

 

Here is the size difference between the APM 100, Kowa 82, APM 70, and Nikon 18x70.

Pinac,

 

Thanks for the pics and review. 

 

I note you are using the Swaro head to mount these. How is it handling the weight and size?

 

cheers

Great comparison picture...

 

have you got any pics of the 70's with the 24mm eyepieces?

 

cheers

The weight of the APM 120 was also understated before it came out (as 9kg but turned out to be 9.6-9.7kg). The 82s use the body of their smaller brother, similarly as the 120, and maybe only the difference in the weight of the optics was initally factored in and the weight of the additional segment of the body (containing the lenses and their cell) that is added on to the body of 70s was not. I was very sceptical about the difference in weight between these two models being actually so small. 4.4kg must be a real life measurement and not an estimate.

Pinac and Mike,

 

Thanks for sharing some first impression and pictures of the new 70mm APM ED's. 

 

Amazing Mike, how you demonstrated with your pictures in post #13 above, that the Nikon 18x70's are actually small binoculars lol.gif

 

Look forward to more reports on how these APM 70 ED's do under the stars and compare to the Kowa's, Vixens and other APM's  smile.gif

Thanks for your review!
I'm thinking of getting one of them.

Considering only $200 price difference between 70mm and 82mm, is there any advantage of 70mm over 82mm?

I have to carry a tripod and a mount for both binos and I drive to my observing site. So I'm guessing there's no reason for me to choose 70mm over 82mm..?


I imagine the 70mm model primarily targets the birding community and the 82mm model targets both birding and astronomy folks. IIRC the 70mm is only available in 45deg.

For both the 70mm and 82mm, 90° versions will be available in a few months.

Seems Vixen 70ed is becoming a collector's item first.

If you fly a lot, I'm thinking the 70mm may be the perfect travel binoc with a pelican 1510 case

An advantage of the 70 mm model is its wider field, you can get 4 degree instead of 3.4 degree for the 82 mm version. 3.4 degree is a little bit narrow for several beautiful objects, like Orion's belt, the cirrus complex and the Hyades. I think the 70 mm 90 degree combo is a very nice intstrument, with 24 mm Panoptic you get a 16x70 binocular.

That was just for the very first few views in daylight with the bino positioned more or less horizontally. For real use, the Swaro head is too weak in my view; so with anything heavier than about 2.5 kg that needs to be tilted more than 15 degrees, I use a fork mount.

My Manfrotto 475 and 501 HDV head will do fine with either.....worked fine with my 100 APOs.

 

I'm thinking on waiting on the 90 degree models since I do a lot of zenith viewing; literally a pain in the neck with the 45 oculars.

I agree that for zenith or close to zenith viewing, 90 degrees is the much better choice (I myself prefer 45 degrees but I go mostly up no more than 70 degrees or so).
