Have Pentax, will Nikon?

Given my investment in lenses, should I stay with Pentax or is now the time to switch to Nikon/Canon?

I have a Pentax K100D, an entry level DSLR. I've been taking a few classes and though I am fond of the camera, some things about it annoy me ... very slow autofocus, missing many features etc. I have three lenses, a Sigma Kit Lens 18-55mm f/3.5- 5.6, a sigma 50mm f/1.4 and a sigma 70mm f1.4. All K mount lenses so will only work with Pentax.

I hardly ever use the 70mm but I use and love the 50mm f/1.4 a lot. It was a reasonably expensive lens. The 70mm was a gift that I'm thinking of selling no matter what.

The reason I am thinking of switching to another brand is I want to upgrade my camera body and the two teachers of the classes I attended both said that though they loved Pentax and what they had done for the photo industry, that as a DSLR brand it was probably on the way out. Availability of gear is next to zero where I live now and I'm worried if I purchase a new Pentax body in 3 years I'll regret it when I am looking for new lenses/gear.

But then theres the lenses... and my familiarity with the Pentax interface.

I'm really in two minds over this and could use some outside perspective.

The 50mm you can replace on any cropped sensor canon/nikon dslr for 350, so that's not a big deal . You can pick up a VR lens 18-135 zoom just fine with just about any nikon or canon kit you buy, or buy a body and get them super cheap aftermarket.

I'd sell all the lenses and the body and go with whichever canon/nikon you like better. You don't have a crazy amount of glass on the pentax yet but if you continue you will probably acquire more and make switching down the road that much of a barrier.

Pentax makes some fine cameras, I don't follow things closely enough to know whether they are on their way out, don't consider switching without renting your prospective camera for a week or two and spending some time with it to tell if it's a direction you're interested in going.

You don't really have a huge investment in lenses, but you're also not going to get a ton of cash for this kit on trade in. The one thing you can do with the current body is use the lovely SMC Pentax A 50/1.4 and 45/2.8 manual focus lenses from the 1970s/80s. These are epic bits of glass, and will teach you about manual focus. They're also really cheap these days.

Firstly, you can use a k-mount adapter on a Sony Nex cameras. Not DSLRs per se, but APSC sensor that will offer better performance than your current camera for sure.

Secondly, if you're selling the 70mm, the 50 could be bought for circa $350 or so second hand quite easily I think.

Thirdly, people have been saying that pentax is going out for quite some time now, but they're still around, and the buy-out of the retail arm by Ricoh will probably provide some more investment. They will never be like the big two, but they're not gonna disappear any time soonish.

Fourthly, if you move away, be aware that canikon do not have in-body image stabilisation, nor produce DSLR bodies that can take AA batteries. That may not be a big deal for you, but be aware.

Fifthly, you may find the differences over-rated. The current sensor in the pentax k5, for example, is the same sensor as what's in the Nikon d7000 and SonyA580 - a good sensor.

I'm not saying you should stay with Pentax - the dearth of equipment and prices etc are a cause for concern, but I don't know what moving away would give you necessarily, beyond Nikon's much better flash system and a somewhat wider availability of lenses.

You don't really have much of an investment in lenses, so if you want to always have a wide range of options from the true industry leaders then move to Nikon or Canon. Its that simple. I'm truly surprised that any other brands continue to try to compete - they certainly don't produce products that are in the same league.

When I was looking at Pentax, I went with the K10D over the K100D. I got rid of all my Nikon equipment. I was really tired of (at the time) no metering through older lenses and VR only available on certain lenses. Pentax seemed to know that they couldn't ramp up production of new lenses so they welcome using older glass on any of their bodies.

I've never regretted leaving Nikon, or buying the Pentax. Take a look at the upper level Pentax bodies. My K10D is my only body, and it has been utterly reliable over the years.

There have been a lot of intense comparisons of the Pentax K5 and Nikon D7000, given that as the poster above mentions, they share the same sensor.

Lenses tend to keep their value so you could easily sell your lenses & replace them with used lenses for whatever system you decide to go with.

Pentax is a fine company and makes good equipment and I don't see them or the K-Mount going anywhere any time soon, but the fact of the matter is, the market has way more Nikon & Canon stuff so switching does confer an advantage in terms of gear available.

My 50ยข on lenses and the differences between Nikon and Canon.

In 1986 Canon changed their lens mount to a new format that's friendlier to autofocus and older Canon lenses don't mount on newer Canon bodies.

Nikon's F-Mount hasn't changed since 1978 and changed only slightly then so older Nikon lenses will mount if they have been "AI Modified" - I have Nikon lenses that date back to 1972 (based on serial number).

However Nikon's lens-to-sensor distance is longer than Canon's so you can buy an adapter to use Nikon lenses on Canon cameras and not v.v. You can buy an adapter to mount Pentax lenses on Canon bodies so I guess the Canon lens-to-sensor distance is also shorter than Pentax's. I assume your 50/1.4 is manual focus? If so you can keep it if you switch to Canon & use it pretty much the same.

There are a lot of quality used Nikon lenses out there that will work just fine on the moderately high ranged Nikons (D7000 and up) and with limitations on the lower end Nikons. These lenses will also work on Canon cameras with an adapter.

There are fewer used Canon lenses on the market.

Checking B&H's used lens department I find 74 Canon EOS mount lenses vs 101 Nikon Autofocus lenses + 61 Nikon AIS mount (manual focus) lenses. 74 vs. 162. This is one of the reasons I chose Nikon over Canon, but remember you can mount Nikon lenses on Canon bodies (without any AF capabilities). Incidentally there are only 13 Pentax autofocus lenses & 51 manual focus lenses.

I prefer the ergonomics on Nikon cameras to Canon cameras and from what I hear when a Canon user picks up a Nikon it's intuitive, but from experience as a Nikon user picking up a Canon, I was kind of lost - how do you change ISO? on Nikon there's a dedicated button, on Canon you have to sort of guess the button & it's harder to change on-the-fly. But ergonomics aren't a dealbreaker.

Canon is currently tops in HDSLR (using an SLR camera for video, in fact some scenes from Black Swan were filmed with a Canon 7D). Nikon's newly minted D4 and presumably their around the corner D800 may challenge this - Canon has the first mover advantage.

Nikon cameras tend to be better at low light situations than Canon cameras - higher ISO, etc. but I won't say this unequivocally, I'm mostly passing along hearsay.

> I was really tired of (at the time) no metering through older lenses

This is only true on the lower-end bodies and first gen (D1, D100 era) DSLRs and on lenses that pre-date AF (1986, the same time Canon changed their lens mount entirely) - so don't let this pejorative dissuade you, but this post is another great example of the fact that Pentax makes great stuff. Every choice you make is a matter of tradeoffs - Pentax does stuff Nikon & Canon don't and v.v.

So to sum up:

Pentax makes great stuff.

Nikon & Canon's dominance means there is more stuff out there for these cameras - that's a simple fact.

Higher end Nikon cameras work perfectly with very old lenses, so if availability of lenses is your prime concern, Nikon is a great choice.

Canon D7 and D5 are the "go to" cameras for video.

Canon can mount Pentax and Nikon glass with adapters (manual use only and I'm not sure about metering).

Pentax is not on its way out. Since the merger with Ricoh, they have more resources, not fewer, and there have been rumors of Pentax rolling out a full-frame EVIL camera and so on.

The only reasons to switch would be if you want to go full frame right now or if you need 24fps videography right now.

Switching to Canon or Nikon won't make your photos better. Pentax makes awesome DSLRs. The Pentax system is backwards-compatible with a large library of quality K-mount glass. If you want to upgrade, you can get a great deal on a K-5, and it will be a terrific camera for years to come. It's arguably the best DSLR in its class right now.

It's silly to talk about Nikon and Canon having dozens upon dozens of new lenses. You don't need three 50mms and three 85mms and so on. The only issue with Pentax is the relative dearth of pro quality zooms - they have terrific primes, but their zoom family is a skeleton crew at the moment.

Availability of gear is next to zero where I live now and I'm worried if I purchase a new Pentax body in 3 years I'll regret it when I am looking for new lenses/gear.

I own a Pentax K-x that I bought two years ago as a two-lens kit: their 18-55mm kit lens, and a 55-300mm f/4-5.8 lens. The 18-55mm was traded in for a Sigma 17-70 f/2.8-4, and I also have an smc Pentax 50mm f/1.7 lens I bought second-hand.

As long as Sigma and a second-hand market is in existence, I'm not too worried about lenses not being available for my K-x. I am more worried about flash guns, as Pentax's own flashes aren't so great, and while Vivitar, Metz, and Sigma all make Pentax-compatible flashes, the breadth of range is nowhere up to where the Canon/Nikon duopoly is at. The cameras themselves also worry me, as various rumor sites have it that both the K-5 and K-r (the K-x successor) have been recently discontinued, leaving Pentax with only the Q-series mirrorless camera and the 645D medium-format camera. I do have hope that Ricoh will invest into Pentax; by the time 2012 is over, we should be seeing a totally revamped range from Pentax. Personally, I'd hold out until the year is out if you can, and if Pentax looks like they're barely treading water at that time, then it may be time to switch.

Is the pentax system holding you back for your photography? Would the other two systems offer something you need/want that is worth the price/time/effort of switching systems?

Am I the only person here who has never heard of a Sigma 70mm f/1.4 lens? Are you sure that's what you have?

Regardless of that answer, I don't see Pentax remaining in the DSLR biz for the long haul.

You can switch now, or you can switch later, but one way or the other you're going to be switching at some point if you continue to shoot with a DSLR.

The day Pentax announces they're out of the DSLR business is the day that the resale value of your existing lenses will drop substantially.

I love using Pentax cameras, I tried the Pentax K5 yesterday (I'm currently visiting Sydney where you can find Pentax in the stores) and I loved it. I also tested the Nikon D7000 and the Canon EOS 60d and didn't find them as comfortable to hold, though I'm sure thats just familiarity more than anything. In terms of what the other brands offer, its (probably) a longer life and more availability for gear, and better resale for whatever I invest in.

I got the measurements on my lenses wrong, they are actually this one and this one. I think I was using the film equivalent measurements (and got it wrong on the 50mm).

So ... I'm leaning towards upgrading to the K-5 but still thinking about it and when I'm back in the Philippines I might rent a Nikon and Canon and try them for a week. For me its a significant investment to change so I want to make sure its right for me.

Thanks everyone for the great advice.

Best answer: Let's look at this from another perspective. If Pentax goes out of business, perhaps you could pick up a Pentax K5 body at a decent price. That's an amazing camera and it would last you ages.

That being said... if you're seriously considering switching systems, you should try to hold off as long as possible so you can really do your homework.

Switching to Canon is easy since Canon is a popular brand, but technically, they seem to be falling behind these days. It would be a shame to switch to a system in decline.

Switching to Nikon is easy since Nikon is a popular brand. Technically, they're not doing anything particularly revolutionary, but they're not falling behind. As the saying goes among the pros, nobody ever got fired for buying a Nikon.

I'm going to recommend something different though. If you're going to switch systems, you should seriously consider the recently released Sony a77. There hasn't been a major leap in technology of SLRs since the first digitals were released. With each new model, specs got better, options were refined and the bodies got smaller and rear screens got larger. It's been a constant evolution. But the recent Sonys mark the first real revolution in terms of DSLR camera bodies, and the things Sony is doing now will probably be common among all camera makers in five to ten years.

I'm talking about the electronic viewfinder.

A DSLR viewfinder is basically a piece of glass directed toward a mirror that redirects the view through the camera lens. When you take a picture, you hear a "THWAP!" sound as the mirror flips away so the sensor receives the image instead of it reflecting off the mirror.

Lens -- Mirror -- Viewfinder
Lens -- Mirror -- Sensor

I'm sure you know that, but I mention it mostly as a reminder.

The new Sony's use a translucent mirror which allows most of the light to always reach the sensor, while redirecting just a bit of it to an electronic viewfinder. In other words, when you look through the eyepiece, you're looking at a screen (a tiny monitor). This monitor shows you what the camera is DOING rather than just showing you what the lens sees.

In other words, if you raise or lower ISO, instead of getting an indicator in the viewfinder, you actually see the shot brighten or darken in the viewfinder. If you boost exposure compensation, you SEE the difference in your viewfinder. Like to shoot in black and white? You can set the camera to do so, and you'll SEE the black and white view through the viewfinder.

There are literally so many advantages to this way of shooting that I could write twenty posts about it. I thought electronic viewfinders were gimmicks until I spent an afternoon shooting with a Sony a77. I spent that whole afternoon saying wow again and again as I realized more and more things the electronic viewfinder enabled me to do. Here's one more example: is the shot in focus? With an electronic viewfinder, you can zoom in WAY IN to make sure the focus is sharp before taking the shot. That's crazy cool.

Here's a review I wrote about the viewfinder in the a77 if you want more info.

tl;dr - Pentax cameras are awesome. Upgrade to something like a K5 and you'll be happy... but if you're going to switch systems, make sure you don't put yourself in a position where you'll want to switch again in a few years. Get the most bang for your switchin' buck.

Best of luck!

If Pentax goes out of business, perhaps you could pick up a Pentax K5 body at a decent price.

FWIW, there's a $300 instant rebate on the K-5 right now at Adorama (and maybe other places).

Response by poster: Hi All,

I appreciate everyones input. I'm not sure if I've jumped from one under supported system (Pentax) to another (Sony) but I've ordered an A65 after trying out the Nikon d5100 and Canon 60d and the Sony range.

If anyone wants to buy my pentax or those lenses get in touch! :)
