TTArtisan 35mm f1.4 lens for Micro Four Thirds cameras


The TTArtisan 35mm f1.4 is an inexpensive manual focus lens. It has no electronic contacts, no autofocus. I'm using this lens with Micro Four Thirds (M43) cameras but you can also purchase it for APS-C cameras. In this article I share my thoughts and experience using this lens. I'm not a professional photographer but I hope my real world experience can be helpful.

Build and handling
It's small, it's not heavy but it feels dense. The focus ring is smooth. Everything is well put together. The aperture ring clicks, in a soft way. Previously I owned the TTArtisan 23mm f1.4, that was also very well made but this 35mm is smaller and a very different shape. Actually, it reminds me a lot of the Olympus 45mm f1.8 in size and shape. Later in the 'competition' section I'll discuss this more. But there's something quirky about this long cone shape that I sort of like.

The lens cap is metal and it screws on the front of the lens. I know a lot of people don't like this type of cap, as they feel it takes time to take on and off, but I actually like it. I usually take the lens cap off and put it in my pocket while taking photos. It find it is fine. I like the security of knowing the lens cap will stay on when the camera is in my bag. 

A lens hood was not included. So far I haven't felt the need to get one. Flare hasn't been much of a problem. The lens thread is 39mm, I little quirky! That is a sort trend with this lens. 


As you turn the focus ring, the lens extends about 5mm. I don't find this annoying, it's ok, but just something to mention. There are distance markings on the lens. The minimum focus distance has a hard stop which is nice. But when photographing at infinity, I found it best to have the ring just before the stop, just on the first part of the infinity symbol. I had the same trouble with my Pergear 25mm f1.7. It's a shame because you can't just twist to the stop, you must look at the lens barrel.

I have used the TTArtisan 35mm f1.4 on two cameras. Previously on the Lumix GX9 and now on the Olympus E-M5 II. On both cameras the lens is well balanced. It is of course a little heavier than the lenses I usually use, such as the Olympus 17mm f1.8. However, I have become used to it. I feels better than the TTArtisan 23mm f1.4 I had in the past. One thing I didn't like about that lens was the weight, my GX9 was always front heavy but with this TTArtisan 35mm f1.4, I don't find that.


Focal length
On M43 the 35mm focal length is equivalent to 70mm in full frame terms. I find this a strange focal length, for general photography I don't find it wide enough and it isn't a very long telephoto. This unconventional focal length is a bit of a challenge and that's a nice feeling. 


Aperture
It ranges from f1.4 to f16. I mostly use it at f1.4 only because that's the star feature of this lens. It's just such a bright lens. Together with the 35mm focal length, you can really make your subject stand out by blurring the background. Of course f1.4 also means it's possible to use the lens in low light conditions.

I should warn that sometimes it is very difficult to get sharp focus at f1.4. On the GX9 the focus peaking and magnify options are easy to use. On the E-M5 II, I use focus peaking but I have to press a button to activate it and often it's difficult to see the peaking ants. Perhaps this is all part of the fun to make you take time to get the photo. 


Close focussing distance
It's very good, at just 28cm. It works very well for flower photos. With extension tubs you can turn this into an almost-macro lens.

Image quality
I haven't done any scientific tests but to me, it is a very sharp lens. Whether or not you get sharp photos is probably down to your skill with the manual focus rather than the quality of the lens itself. For this price especially, it's excellent. The out of focus areas render nicely too. 



Real world experience
This is a fun lens. I walk around my local botanical garden and try using the f1.4, can I get a sharp image? It's a challenge! It's compact, it balances well with my camera. I like it is a niche lens. What I mean is, it's not versatile, the focal length is a bit strange. 

I enjoy this lens but it doesn't replace any of my existing lenses. It has its own quirks that make it fun to use on occasion. 

One role this lens could play, is to be a portrait lens. With the f1.4 and a short telephoto, it's pretty good. 


Competition
As I said above, either you get this lens and just accept it's for fun, or you buy it to use it seriously for something like portraits. There are many options, for manual focus, consider the TTArtisan 50mm f1.2. You get a bit more reach and with that slightly brighter aperture, the out-of-focus areas of the picture can be very smooth indeed. It is heavier than the 35mm, very front heavy on my E-M5 II. 

The most obvious competitor for portraits is probably the classic Olympus 45mm f1.8. It's a similar size and it is not expensive, especially on the used market. The image quality is superb. It also has auto-focus and it is lighter. The Olympus is plastic though, I don't mind but I know some others covet the metal, in that case the TTArtisan is definitely the one for you. The TTArtisan focusses closer than the Olympus too. 




The above photos were taken using the E-M5 II on a tripod in the same position relative to the subject. The camera was set to manual, ISO 400, 1/800. 
The first photo (left) is the TTArtisan 35mm f1.4, taken at f1.4. 
The second photo (right) is the Olympus 45mm f1.8, taken at f1.8. 

Notice how much wider 35mm is compared to 45mm. If you prefer the wider view, I'd say the TTArtisan is a good choice because the f1.4 does provide a creamy out of focus background. However, I personally prefer the Olympus 45mm f1.8, that extra focal length makes a difference. 

Instead of portrait photography, maybe you'd like a reasonably priced lens for close-ups, flower photography for example. I would say the TTArtisan 35mm f1.4 is a good choice. The 28mm minimum focus distance gets you close enough for flowers. For smaller, use an extension tube. An alternative would be the Lumix 30mm f2.8 macro. That's a true macro lens, no messing with extension tubes. The field of view is close too. At f2.8 you will not get the same subject separation that f1.4 will give you. Having said that, for macro that is not a concern. In fact, with macro, you must stop down to get more depth of field. This makes the TTArtisan a bit of a waste because having that f1.4 aperture is the major selling point. Anyhow, perhaps as a second use to portraits, it could double as a good close-up lens that won't break the bank. 


Conclusion
The TTArtisan 35mm f1.4 is fantastic! I say that when thinking about the price and performance. I bought from Pergear, it came in a nice presentation box. There was a quality neoprene bag included too. As a fun lens, it has its place. Maybe a great gift for someone. As a serious lens to replace another, I don't think so. But that's just me, if you really love manual focus, then why not. If you are looking for a reasonably priced portrait lens, I do think the Olympus 45mm f1.8 is a better investment. It's more expensive but the auto-focus and lighter weight is worth it. Having said all this, whatever you get, it'll give you great results. Most Micro Four Thirds lenses are excellent.

Panasonic Lumix 14-140mm f3.5-5.6 zoom lens for Micro Four Thirds cameras

A couple of years ago I bought the Lumix 14-140mm f3.5-5.6 lens. I generally I prefer small lenses. My favourites are prime lenses such as the Olympus 17mm F1.8 for example. But for holiday trips, sometimes a zoom makes more sense as it is more flexible.

In the past I used a combination of two lenses for holiday trips. The Lumix 12-32mm f3.5-5.6 and the Lumix 35-100mm f4-5.6. both are super compact and light - perfect for travel photography. However, sometimes changing lens can be a real pain. You are out and about, snapping away but you can't reach that far-off ship, for example. I have to rummage in my bag, swap over lenses, by that time, the ship has moved, the composition not as I had first seen it.

This is where the 14-140mm lens comes in handy. I can replace both 12-32 and 35-100 lenses with one. The 14-140 is bigger and heavier, but maybe that is ok for the advantage, everything is about balance.

Lumix GX9 and 14-140mm F3.5-5.6 lens

Build and handling
The Lumix 14-140 has a metal mount. Mostly it is a plastic build but very good quality. Perhaps a carbon mix because part of the lens feels cold like metal. There's no creaking or flexing. As you twist the zoom, the plastic inner barrel extends. At 140mm it is about twice the length of the lens at 14mm.

The lens is much fatter than lenses such as the 12-32 or 35-100. But it feels fine in your hands as you zoom, for example. The length of the lens is also not too long, on the GX9 it is still a relatively compact combination.

The 14-140 is not too heavy. It works well with the GX9. I have found using the JJC grip on the GX9 makes it a bit more comfortable. But even without the grip, it is fine. I have also used the 14-140 on the Olympus E-M5 II, it doesn't need an extra grip at all, it's comfortable to use.


Something I find special with this zoom lens is how you can switch on the camera and immediately it is ready for use at 14mm. With the 12-32 and 35-100 lenses I have to twist to open them first, before being able to take a photo. With the 14-140 it makes a difference to have it ready immediately. Easier to capture those surprise moments.

A lens hood is included, it is plastic but good quality. It can be put on backward to store it. But I am not a big fan of this hood, it twists on and I find it a fiddle. Although I generally find such hoods a fiddle on any lens.


Focal length
14mm is equivalent to 28mm in Full Frame terms. Starting at 14mm makes this a versatile lens. It would've been nice to have 12mm but still, I will not complain about those two millimetres too much. 140mm is equivalent to 280mm in Full Frame terms. 14-140mm is an extremely flexible range. Everything from close to very far.


Aperture
The 14-140 has a variable aperture, at 14mm it starts at f3.5. At the telephoto end, 140mm, it starts at f5.6. I know many will moan but I think these apertures are impressive. If you don't like the aperture changing, set it to f5.6, it'll be fine throughout the range.

For the majority of daylight photography f5.6 is perfect. When there is less light, at 14mm, f3.5 is ok, not great. F2.8 would've been better of course but there have to be compromises as the lens is so compact.

For bokeh (background blur), you may think that f3.5-5.6 would hold the lens back. However, aperture is only one ingredient in the recipe for creating that out of focus look. Because this lens is such a long telephoto, to 140mm, even at f5.6 there can be plenty of background blur and separation form your subject.


Image stabilisation
The lens has stabilisation. There is a physical switch on the lens barrel to turn it on or off. I keep it on. The GX9 (and many other Lumix cameras) has Dual-IS. This means the lens IS works with the camera's in-body IS. It is very helpful when composing at long telephoto focal lengths. Also, for low light photography of static objects, it enables you to handhold for longer shutter speeds.

When used with the Olympus E-M5 II, I turn off the lens stabilisation and rely on the Olympus IBIS. There's no dual-IS with Olympus/OM cameras. I must admit to not noticing any difference in use, the Olympus IBIS is great.


Close focussing distance
You can get pretty close. It isn't macro of course, but for the occasional close up on a trip, it works very well. Excellent from flowers and similar photography. For those holiday trips where you are walking in a park, you can take a photo of the sea in the distance and turn around, take a flower photo. Flexible! The focussing is snappy.

Image quality
Fantastic. Sharp images throughout the range. I am just speaking from what I see. I haven't tested in a scientific way. For the intended use, travel, it does the job.


Real world experience
I used the 14-140 with the GX9 on a trip to Rome. It was great having the flexibility to photograph just about anything. For example, I was on the Castel Sant'Angelo. I could see At Peter's in the distance. I took a nice photo from there that otherwise, without the 14-140, I would not have been able to capture. Switching so quickly between near and far is great for travel photography. It gave me some freedom.

One evening at the Forum I found it difficult to get clean photos. With time and effort it is possible, but when on holiday, you don't have time. On other evenings out, I switched to my Olympus 17mm f1.8.

Despite the 14-140 being easy to carry during my trip to Rome, I found myself often wishing for a more compact system. When I used my Olympus 17mm f1.8, I felt more comfortable. In town especially, on the streets, taking out the camera with the 14-140 was a chore. Carrying it round my neck with it hanging down, it got in the way. Imagine you are in a shop with bags in your hands plus the camera round your neck and this lens sticking out!

Perhaps the 14-140 is more suited to a hiking trip, that sort of thing. For a city trip, although fun to have the flexibility, perhaps a smaller combo would be better. This all depends on you though, we are all different, these are just my thoughts.

Three zoom lenses for size comparison. Collapsed without hoods.


Competition
As I've mentioned, an alternative might be to use two lenses, a general purpose plus a telephoto. You have to switch between lenses but otherwise, it can be a nice choice with some advantages of a more compact camera plus lens combination. But by compact I mean the Olympus 17mm F1.8 and Lumix 35-100mm f4-5.6 for example.

There are many attractive general purpose lenses for m43. The Olympus/OM Pro 12-45mm f4 is a high quality lens. The downside is the size is only a little smaller than the 14-140 but without the telephoto range.

Olympus/OM have the 14-150mm f4-f5.6. It is a direct competitor to the Lumix 14-140. From all accounts, it seems similar. You get 10mm more reach. Although there is no IS, if you have a Lumix camera the 14-140 is a better choice just because of this reason.


Conclusion
The 14-140 is an excellent lens. It is extremely compact in size for the focal range it covers. The price is reasonable and perhaps you can find a bargain. As a replacement for prime lenses, I am not sure. It is a personal thing, for me the tiny m43 primes are a better fit. Although, the flexibility of the zoom range, it is such a good feeling not to have to switch lenses. There are just too many choices in the world of m43!

HP OfficeJet Pro 8610 wireless does not work, can't connect to the printer

All of a sudden, one day you cannot print wirelessly to your OfficeJet Pro 8610 wireless printer - you get this message:
You cannot use the device's wireless function because it has been disabled. For more information, contact your network administrator or the person who set up the device.

It took me a long time to find the answer and then to get it to work was not easy. This is what I did:

Go to the printer's screen

Press the back button four times (this is the difficult part, sometimes it just doesn't work, you have to get the timing right)


Keep trying, eventually you should see this screen:


Select Support Menu


Use the up/down buttons, select Connectivity


Enable the WiFi 

After, the blue WiFi light flashes. Go to the Settings menu, Network Settings, Wireless, use the WiFi wizard, it will search for the network and you can enter your WiFi password. The blue light will stop flashing.


Reference
The following link explains about the 8710 but it's very similar to the 8610 model. It's very helpful, there are even more tips on how to reset the printer too.
