Tiffen Ultra Pol Panoramica

Migliori Filtro polarizzatore circolare Tiffen 4 x 4" 85 Ultra Pol combina un filtro di conversione a 85 colori con un filtro polarizzatore circolare per fondere gli effetti di entrambi i tipi di filtro in un'unica, pratica soluzione.

La conversione a 85 colori del filtro fornisce un effetto caldo e riduce la temperatura del colore da 5500K a 3400K, consentendo l'uso di pellicole bilanciate al tungsteno in condizioni di luce diurna.

L'aspetto polarizzante circolare Ultra Pol del filtro aiuta a ridurre notevolmente i riflessi e l'abbagliamento filtrando la luce che è diventata polarizzata a causa della riflessione da una superficie non metallica. Ciò si traduce in un notevole aumento della saturazione di cieli e fogliame, nonché immagini più nitide quando si fotografa in condizioni di foschia. Un polarizzatore circolare differisce da un polarizzatore lineare in quanto supporta l'uso completo delle funzioni di messa a fuoco automatica ed esposizione automatica di una fotocamera.

Il fattore di filtro totale è di circa 6x, che richiede una regolazione di 2.6 stop per un'esposizione normale. I filtri Tiffen sono realizzati utilizzando la tecnologia ColorCore, un processo che prevede la laminazione del substrato del filtro tra 2 pezzi di vetro ottico e la levigatura piana con una tolleranza di 1/10,000 di pollice. Questo filtro misura 4 x 4" / 101.6 x 101.6 mm.

Combinazione di polarizzatore circolare Ultra Pol e filtro di conversione del colore ambra 85.
Per ottenere risultati normali, il fattore di filtro totale di circa 6x richiede 2.6 stop di esposizione aggiuntivi.
Il filtro di conversione del colore Warming 85 riduce la temperatura del colore da 5500K a 3400K per l'utilizzo di pellicole con bilanciamento del tungsteno in condizioni di luce diurna.
Il polarizzatore aiuta a ridurre notevolmente i riflessi e gli abbagliamenti filtrando la luce polarizzata a causa della riflessione da una superficie non metallica.
Elimina la foschia in paesaggi lontani e fornisce colori più saturi e vivaci.
L'effetto polarizzante è più forte se utilizzato a un angolo di 90° rispetto al sole.
Rispetto a un polarizzatore standard, il design Ultra Pol punta ad aumentare l'effetto polarizzante per una maggiore riduzione dei riflessi e una maggiore saturazione del colore.

Basic mouse that works - - for now.
Size: 1 Pack, Style: USB Receiver, Color: Blue
I ordered this mouse (in blue) to replace the recently deceased exact same model that I've used for the past 2 or 3 years. I like the simplicity of the M185 mouse and mostly the best bang for your buck! I caught this one on sale for less than a ten-spot, so I thought, "why not." I'm hoping that this one will last a bit longer than my two previous M185 models, that averaged about 3 years each. This model seems plagued by a short life span and is predisposed to mysteriously and suddenly dying, without any obvious symptoms or warning of any kind - - you're working and clicking along, going about your day, when suddenly the cursor on the computer screen freezes and that's it. Nothing, zero, nada. Funny thing, I'm very careful not to abuse or drop the mouse, and keep a fresh battery installed and watch for leakage and all that stuff - - they just stop working, and I assume it is caused by some sort of inherent electronic fault in the circuitry of the previous M185's. Due to my loyalty to the brand and model (and since it was on sale) I decided to give it one more shot. They say that "third time's a charm". I like the fact that the M185 is simple and uncluttered with extra buttons that I would never use for my purpose, which is simple web-browsing and the occasional text document production. The feel is solid, not heavy, but not cheap feeling, either. I'm used to the shape of this mouse, which to me is quite comfortable for long sessions, another reason why I kind of wanted to stay with this model. The buttons have an audible "click", which doesn't bother me at all, and the wheel moves smoothly and also has a clicking operation (which I rarely ever use). The overall surface of the mouse has a matte finish, but like my previous models I'm sure it will eventually wear shiny spots where my fingers reside and will attain a more "well-used" look in time. Connecting it was a breeze, too. I just plugged the dongle into a spare rear usb port of my desktop, and the mouse connected instantly, no problem. The dongle can be stored safely inside the battery compartment, so you can take the whole thing out of the house if needed for use elsewhere. The speed of 1000 dpi seems just right for my purposes. The one I ordered even came with its own AA Duracell battery, which I wasn't really expecting. This mouse also enters "sleep mode" when you don't use it for a while, and I can't say how many times I've got up and left it on all night. And that's not hard to do, as I'll explain next. The only real negative to this mouse is the absence of any easily visible status indicator of it's on / off switch. The rear housing of this mouse is matte black, including the tiny switch where you turn it on and off with your fingernail, with only a very faint "on" lettering (also black), and very hard to see with my aging eyes. The laser is not lighted or visible when on, also adding to the confusion, especially in a darkened room. So, as a workaround, I took a tiny drop of green paint and placed it down inside the switch slider to visibly help indicate the "on" position, and likewise a dot of bright orange for the "off" position. Many of Logitech's more expensive models (and a few other manufacturers) include this color-coded switch indication. I guess for the $$, they had to cut corners somewhere - - a minor complaint. In summary, this is a good basic mouse that works - - let's hope that this one will last longer than its two predecessors.

Dependable, Reliable

As advertised. Logitech, best mouse for your hard-earned cheddar! It’s not that the (years) old Logitech mouse failed in any operational way, it just got that gummy, sticky surface texture that’s impossible to remove. While shopping for a replacement I noticed an off-brand mouse/keyboard combo and thought, “hey, 2 for 1”…mistake. All was well for about three weeks, long enough that when the gremlins arrived I didn’t immediately associate the new hardware. For the purposes of this discussion, gentle reader, know that I run legacy (what I affectionately refer to as, “Lazarus”) builds. Rigs that started life running Windows Vista/7, died, and that now, resurrected, run 10 and 11, and all that that implies. So, when a mouse started stuttering, of course I thought it was a gremlin in the machine, right? I spent more days than I am comfortable sharing with you pouring over processes and background apps, and registry trims…before Accam’s Razor suggested I eliminate the mouse as a variable. Changing the battery was ineffective, but when I swapped in the ooold Logitech…Yahtzee/Bingo/Booyah…smooth and precise…butter! All I needed was a new Logitech mouse. So, if you’re here you likely are having mouse issues of your own, or you just need one that works…this is it! 😉

Nice and a great value.
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
Hey, it works well. Just plug it in and you are ready to go. Only issue, minor, no light or color coding on back to indicate on or off.

Smooth and ergo nice mouse.
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
I needed this little thing quickly and got it within 2 hours of ordering. It was only an extra five bucks to get it now. Would have burned more than that in fuel. Works exactly as I would have expected. Perfect.

This is a dandy little item. Easy to use straight out of the box, No fancy bells and whistles.but why should a mouse try to replicate commands that are on the laptop?
