The FFP optic will allow you to use mil or moa reticle to range and adjust zero. If you get SFP, your reticle will not magnify throughout it's zoom therefore your mildot, milscale, moa reticle has little more value than a standard duplex reticle. If you can afford it, get the FFP. Even if you are not into ranging or dialing in scope for specific shots at distance using turrets (vs Kentucky windage)...you will still have this option. The only thing you lose with the FFP is money, but you gain capability.

Every Vortex Viper Pst Scope has a manufacture's part number. This one is PST-416F1-M. You will notice that the letter after the 416 is an "F". This will signify that it is a First focal plane scope. If the letter is an "S", then it will be a second focal plane. The price is also an indicator. The first focal plane is much more expensive than the second because of a more complex construction. The crosshairs are etched on the lense, not painted.

It all depends on what you are wanting to do with te scope. On first focal plane the reticle size changes with the magnification. This allows for the Mil Dot or other hold off/ranging functions to stay consistent through the full range of magnification. 1 Mil or MOA at 4x is the same at 16x. A second focal plane scope the reticle is the same size no matter what the magnification is. 1 Mil or MOA is only that at a set magnification, usually the highest on the scope.

i have the same question. i understand the difference between FFP and SFP and im sure the OP does too. but in the item's description, it says "Options of First Focal Plane or Second Focal Plane Reticle". what the hell does that mean?? you can switch the reticle back and forth between the first and second planes? there are no options to choose which model when you add it to your cart. so which one do you end up with? can someone answer that without trying to educate us on the difference between FFP and SFP?

It depends on what you are looking for FFP allows you to range your target on any power SFP has to be set to a preset power for ranging IE. 9x for the mill dot to be the right size. I love FFP but it dose run about a 1/3 more $$

According to the part number, this is a First Focal Plane model with the MRAD reticle

Go read this article on FFP VS SFP and then come back if you have additional questions. http://www.primalrights.com/forum/article.php?a=4789

Hi Matt,My first scope.The retical 'changes size' with the magnification so the mill dots are always correct.That, I beleive, is first focal plane.Hope that helps!

You have the option to do either. There is a switch on both the lenses that come in this package that can be set to Automatic OR manual. This is a very user friendly camera, especially for beginners.

It's 2nd focal plane. You're not going to touch a qulaity 1st FFP scope for less than $1K. This is a great scope.

I use the 3 and higher for imaging Planets, thet 2X can be used for doubling the power at the eyepiece. The 127 eq is a great scope you should have lots of fun. I had a C5 at one time loved it.

MRAD, AND it's also 2nd focal plane.... which they didn't put either in the description of the item when I bought it....

Hello Phileein,Thanks for the input, I ordered the 2 lines kit. I have trouble looking through viewfinders thus my need for live view.I am awaiting my new camera and will do a review after I get itThanks again

It is recommended to use 400 because it is more sensitive to light. You could use 200 but with larger apertures or slower times, which is generally more inconvenient.

If you mean FFP (first focal plane), then it should say that in the description. The one I ordered and received is FFP.

I'm looking at the same two as well. Any input would be appreciated.Thanks!

I tried both, sent this one back. There is noticeable difference in sharpness when zoomed in.

MOA and MRAD is the turrent adjustment type. You can range in Mil radians and choose either one quarter inch at one hundred yards or in one tenth mil radian. I believe this scope is First or Front focal plane and Mil Radian adjustments. I have two. Excellent scope for cost.

They actually make both and they look the same so I can't tell from the picture. The one I purchased is 1st focal plane.

This Focal Reducer will screw in where the back is. You unscrew the back, screw this on, then screw the back back on. Also, this is really designed for Astrophotography. It will work for visual use, but most people get this for AP.

I believe they are interchangeable......wonderful, warm sound.....fabulous speakers.....though I traded up for Focals. But for the money these Definitive are fabulous. Be sure to break them easily.

Yes. There are a few of them. Some with optical glass in them like the one I bought, which makes up for the difference in mount to focal plane in FD mint vs EF mount. The extra piece of glass can findings cause some haziness though depending on the weather
